Interesting article. There is an old saying - "One man's cost is another man's revenue."

When energy intensive industries and consumers pay high costs for natural gas, oil and electricity, there is very naturally a group of natural gas suppliers, oil companies and independent power generators that are quite happily banking large revenue increases.

Your detailed description of the relationship between windmills and natural gas consumption may explain why there are so many natural gas and oil companies with interests in windmill companies and especially with wind industry trade associations and lobby groups.

They get a large return on their investment, not by the revenues directly generated from producing power with the wind, but by protecting and even enhancing the revenues produced by selling gas.

Those same companies work very hard to discourage nuclear plant developments and often take the path of completely dismissing them as potential competitors.

The difference is that nuclear plants operating at a reasonable 75-95% capacity factor represents a real loss of market share and a direct loss of revenue to the fossil industry.

Right now, even after a 35 year hiatus in ordering nuclear plants, they produce the equivalent of about 3.5 million barrels of oil per day inside the US and more than 12 million barrels per day world wide.

Imagine what the price of oil would be if we had continued to build the plants!

I found your article ill informed. In fact, very much so. Your facts about wind seem carefully chosen to prove your point and you do so, but only by either intentionally ignoring or missing other information that would show your conclusions to be incorrect. But, beyond that, I'm not sure I understand why you think of renewables as the enemy of nuclear. I've worked on both sides of the house and support both. Both have pluses and minuses. Both are going to be important for the world in the long run. Your dismissal of wind, and by extrapolation all renewables, reminds me a bit of those who dismissed the horseless carriage, the television and the Beatles as short-term fads. If you'd like more information on what is really happening with wind and other renewables and wish to take the time to learn, I'll be happy to set something up.

Texas natural gas consumers paid US$1.7 billion in tax in, if I recall correctly, 2002. I guess natgas for electricity generation is not taxed, but the demand for it drives up the price and increases the take anyway. Is there any federal taxation of natgas? (Just how much of a conflict of interest shouild Chris Powers be acknowledging here?)

The first half of your article was great. However, it seems in the second half that you fully support the theory of Linear, No Threshold (LNT) damage due to radiation exposure.

Have you ever reviewed some of the large volume of literature that questions this theory based on numerous detailed studies?

I highly recommend a few visits to Radiation, Science and Health http://cnts.wpi.edu/rsh/

Please read some of the information about the demonstrated effects of low levels of radiation exposure and consider publishing a revision to your published material that points to radiation as a significant source of human health risk.

Thank you.

Wind is definitely no competitor for nuclear power, but the public FALSE perception that wind, solar or other renewables will be our salvation from fossil fuels is definitely a deterrent to nuclear developments.

At best renewables are diffuse, unreliable, often dirty, generally expensive (unless HEAVILY subsidized) and have yet to made any significant inroads into actual fossil fuel consumption. This despite the fact that all official "renewable" sources of energy have been known to humans for hundreds to thousands of years.

For example - what is the concentration of Po-210 in phosphate? Where does the phosphate in DNA come from - is there any proof that indicates that it is absorbed from food that has been fertilized by commercial fertilizers?

Is there even any proof that cancer is caused by a radiation induced cell mutation, or is that simply an assumption?

Again, I refer you to the rather large body of scientific studies about the measured effects of low level radiation exposure. The Linear No Threshold model is a vast OVERESTIMATION of the measured effects, not an underestimate as you seem to believe.

Please do some research before writting and article that promotes one technology over another.

The problem of installing peaking capacity is more a problem of the users habits. If people turned thier A/C down at home when they are at work then the peak needs would be less. This happended during the last California crisis and it disappeared over night.

In fact, utility planners and independent power producers have historically favored base load plants over peaking units and then found themselves having to modify those machines at considerable expense to accommodate cycling operation. it is a trend that long predates the large-scale introduction of wind machines. Commonwealth Edison has to curtail the operation of its nuclear plants every spring and fall for precisely this reason, and they neither produce nor purchase renewable energy. Moreover, nearly all of the thermal power plants that exist in California today were originally designed as base load machines.

You lament the shutdown of San Onofre 1 and Rancho Seco. San Onofre 1 was shut down by its operator, Southern California Edison, after an economic review indicated it would be far too expensive to make necessary upgrades based on then current prices for natural gas. In the case of Rancho Seco, I would agree that the plant could have been sold to an experienced fleet operator and kept operating, but S. David Freeman, general manager of the Sacramento Municipal Utility District, correctly realized that small utilities lacked the managerial and financial resources to operate nuclear plants. At that time, I'd hazard a guess that none of the larger nuclear fleet operators was contemplating a merchant nuclear plant business.

You are correct that no member of the general public has been killed by nuclear waste. The public's bias against nuclear power is completely irrational. But the nuclear industry has several black marks against it that stand out indelibly in the public's mind. It will likely take several more decades before rational thinking and clear, fact-based, carefully constructed messages from the industry and political leaders begins to displace junk science.

If nuclear waste is so good for society, why isn't this guy storing it at home?

We have given these people fifty years and a gigantic slice of the national treasury to develop electricity "too cheap to meter", and only wound up in a nuclear Faustian Bargain. If we had spent 2% of the money wasted on this dream-turned-nightmare on efficiency and alternative/renewable technologies instead, we wouldn't have to be invading the Middle East for oil.

At the present time, wind power is only a small fraction of the total electrical supply in the country as a whole. Even in California, Texas and Minnesota, the percentage supplied by wind turbines is still only a small faction of what is possible. Given the low wind share of these markets, wind turbines tend to displace the most expensive electricity made, which is natural gas and oil derived, especially from the peaking units, which also tend to be the least efficient and most expensive to operate. Given the current natural gas price of more than $ 6/MBtu Henry Hub price, the delivered prices tend to be around $ 7.3 and up in most parts of this country. And most combined cycle plants (especially in the warmer summer) tend to operate at a 50 % efficiency, not the theoretical 58 %. This make the fuel price of this electricty more than 5 cents/kw-hr.

A modern wind turbine in windy areas tends to operate at between 30 % to 40 % of the rated capacity, and produces some power between 80 to 90 % of the time. Much of the production corresponds to the periods of greatest demand (not couning weekends, since wind speed is not a function of weekday or weekend). So this electricity is even more valuable than "baselad" electricity, since producers tend to have higher production costs for this peak power. Then there is the very dependable concept of pumped hydroelectric storage, such as at Ludington, Michigan, or even Niagara Falls, which is a very effective way to deal with peak power demands.

The only problems wind turbines have is the high interest rates that have to be endured to pay for these capital and job-creating systems. If 20 and 30 year mortgaga rates, or municipal bond rates could be used to finance these, production cost in windy areas (such as 7.5 meters/second or higher average wind speeds at hub height) are near 3 to 3.5 cents/kw-hr for modern wind turbines. Compare that to the fuel costs for natural gas or oil. And this is before any subsidies are thrown in, such as rapid depreciation and Production Tax Credits. In some large scale projects, such as the large scale one in Kansas, production costs after the credits and depreciation are less than 1.5 cent/kw-hr, for this facility that averages 45 % capacity on a year round basis. And if these wind farms are geographically dispersed over a 400 mile radius, the production rate would tend to average out closer to the average electrical demand pattern, since when wind is not blowing in one part of the midwest, it's windy in another part of the midwest.

No wonder this humorless version of Homer Simpson ( or is it really the insidious voice of Mr. Burns ?) wants to diss wind power. He's looking at a future that does not need such an exotic and potentially massively lethal way to boil water.

The cost, as I see it, would be cheaper than a nuclear plant. It would have virtually no associated dangers, be cheaper to maintain, require no external fuels to operate and satisfy the environmentalists. The problem is that to get this type of project underway, financing becomes the largest hurdle. I can personally attest to venture partners as well as every government agency known to man want no part of it. Any comments on why THAT is?

Richard Adams has a major and valid criticism about your LNT belief, and you requested some more information.

I can steer you to the work of Myron Pollycove and others in radiobiology. In general they point out that there are about 240,000 cell mutations per day in each of the body’s 1E14 cells. All of these are caused by events unrelated to radiation within the body, such as enzymes, viruses, temperature, bacteria, etc., and some of which are repaired by the work of at least 40 identified enzymes. Most, however, are not repaired. If not repaired, then the cell either accepts the damage (unlikely, or we would all be dead at a very early age), or commits suicide (apoptosis) when it discovers that it cannot replicate accurately. In comparison a radiation dose of 1 millisievert might cause 1 or two similar breaks per cell in the body. Just based upon simple statistics, the likelihood of one of these breaks leading on to serious consequences based upon an 80 year average life expectancy before one might die of cancer with a likelihood of about 25% is about 1 chance in 1E23. For the likelihood that a radiation induced break from even 10 mSv of total dose might lead to such a cancer is about one chance in 31.4 billion. Obviously the ‘one hit, one cancer’ belief is typical radiation phobia and fearmongering. In reality, the facts show that radiation is an exceedingly weak carcinogen.

Geoffrey Young: your adherence and loyalty to the Rocky Mountain Institute propaganda and the long discredited Keepin and Kats biases and theories is getting to be a joke.

Joseph Yeung: Storage mechanisms. Please identify some, and then quantify the reasonable contribution from any that can begin to meet all but a minuscule fraction of need, and then I will begin to root for your ideas.

Jackson Brown: You cannot use the comedy of court-delaying tactics in the US to tar and feather ALL nuclear power facilities. France operates it’s plants cost effectively, as does most of the rest of the world. I find it interesting that the US nuclear plants that have changed hands and are now operated without all the baggage of the early years, are making money at a wondrous pace for their new owners. Of course, the early comedy of putting ones head in the noose of regulatory delays and environmental court challenges, will not be replayed. When it gets sorted out rationally, and we are tormented by even higher gas and oil prices, or even shortages, we will realize that we should have continued with building nuclear plants 20 years ago, and would not now be in this irrational situation.

George Kamburoff: ‘Faustian Bargain’. Where did you dredge up that particular gem? Your language is redolent of the Rocky Mountain Institute, Caldicott and Nader, while closing your eyes and holding your nose about the fact that the biggest energy subsidies are for renewables, especially wind. Your comments about nuclear waste indicate that you not only know little about it, but are also keen to jump on the bandwagon of throwing snide and glib comments out to impress small minds.

The truth is, Richard, that all sources of energy should make up our generating mix. As a conservative Republican, I argue with the likes of the Sierra Club that we really should be good stewards of all of our resources (nuclear, coal, gas, wind, solar, etc.). But it's important to remember that a good idea doesn't care where it came from. Just because Sierra Club or RMI support renewable energy, doesn't mean conservative, pro-coal and pro-nuclear Republicans have to oppose it. Recognize its true value and work with it.

I have a difficult time believing that someone with your education could actually write something like this without taking the time to investigate the subject more thoroughly. In fact, I debated dignifying your article with a response, but it in the end I couldn't resist. If you can find your calculator and will take the time, with some fairly simple mathematics you can transform the fuel and power generating data provided by the EIA into a form which demonstrates that renewable energy does not cause greater harm to the environment nor does it require more fossil fuel than if renewable energy had not been "invented" (an interesting concept in and of itself). Wishing you fair winds and a following sea ... Edward Settle

http://www.repp.org/repp_pubs/articles/resRpt11/subsidies.pdf

According to this report, over the last fifty years nuclear power has received 96% of federal energy subsidies. This does not include the money spent on military uses of nuclear energy. For an earlier Energy Pulse discussion of this subject, see "US Renewable Energy Markets: Exciting Times Ahead." (5/27/03, Shrikanth Jagannathan)

1) EON (generation corp) in Germany, summer heat wave 2002, 1.2GW of wind turbines produced an average of 1.3% of nameplate KW capacity for the period of the heat wave, making them almost useless. I could hunt up the exact reference again (an industry magazine) if needed.

2) Would be interested to see some honest and readable consolidated $/KWhr subsidy comparisons between thermal, turbine, nuclear over some of the time periods discussed. Everything I've found so far completely debunks the "nuclear heavily subsidized" myth. (e.g. read proposed "energy bill"), US govt historical stats. If anything, the payments toward spent fuel storage and decomissioning are an addd tax which none of it's competitons are hit with, though they should be.

3) Some nearly religious posts from govt. agency members sadly lacking in factual argument. Makes one wonder on their utility.

Would you be able to find the time to mention one or two of those serious flaws? Until then, I will assume that John K. Sutherland's remark above ("...the biggest energy subsidies are for renewables, especially wind.") is false.

According to the study, for the first fifteen years of their development, nuclear power received thirty-three times more in subsidies than wind power, per kWh of generation. For the first twenty-five years, nuclear got 16 times as much as wind.

In response to Richard Stevens, I quote Steve Roelstad of Xcel Energy in Colorado, from an article in the June 2004 Windpower Monthly. Xcel plans to have 500 MW of wind energy on line by 2006: "I'm sensing a paradigm shift from wind needing spinning reserve to a position where wind is an important part of our portfolio."

In my opinion, one of the most important statements from the executive summary is the following: "When cumulative subsidies and electricity generation for all years are accounted for (that is, through 1999), subsidies to the development of commercial, fission-related nuclear power results in a subsidy cost of 1.2 cents/kWh. This compares with a subsidy cost of 51 cents/kWh for solar and 4 cents/kWh for wind. As these numbers suggest, greater generation from nuclear power swamps the greater absolute subsidies to the technology."

Since nuclear power has continued to produce vast quantities of electricity during the 4 years since 1999 and there have been few continuing subsidies, I would guess that the total subsidy cost per unit of produced power continues to drop for nuclear.

For financial decision makers, the key question is not how much one has to spend, but what is the ratio between the investment and the return - also known as ROI. It sure looks like even the Renewable Energy Policy Project has a difficult time avoiding the fact that nuclear power has demonstrated a pretty fair return on investment.

Rod Adams www.atomicinsights.com

“Again, it seems that larger [compared to wind power] early investment in nuclear power paid off in subsequent years.”

In other words, as the study shows, nuclear power has been far more heavily subsidized than wind power. This was still true in 1999, the latest year of the study. From pp. 11-12:

“Although significantly lower than in previous years, direct budgetary funding for nuclear power in 1999 still easily surpassed subsidies to wind, solar, and hydro.”

The figures quoted, for direct and off-budget subsidies combined, are $685 million for nuclear and $38.4 million for wind.

What has been the result? Figure 3 shows that the levelized cost per kWh of nuclear power has been steadily increasing, to 10 cents in 1995. For wind, the cost decreased from 86 cents in 1970 to 6 cents in 1995. That is, in less than half the development time (commercial nuclear power development began in 1948), wind power became cheaper than nuclear power, even if the 1.8 cent/kWh production tax credit for wind is removed.

This differential has certainly become more favorable for wind in the four years since the study was published. In some markets, wind power is now cheaper than natural gas. With this record, and for a development period equal to that of nuclear power, the cost in subsidies for wind would be far less than the 1.2 cents/kWh reported in the study.

Richard Stevens was trying to get some idea of the true cost of wind power, which is a different matter. I will settle this question by saying that wind is the cheapest of all, no matter how the cost is calculated. I know you will be with me on this.

To change the subject a little, we could at least double the output of electrical power from existing hydroelectric dams. See the conclusion on page 40 of the recent study:

www.netl.doe.gov/publications/others/techrpts/AdvFossilPowerSysCompStudy.pdf

If this technology were extended to dams that are not generating electricity now, the increase in electrical output would be far greater yet. Note that no new dams would be needed.

If we put this technology to use, continued to develop renewable energy, and started to get serious about energy conservation, we would not need to build any new fossil or nuclear plants for many years. By that time, we should have progressed to the point where we would not need them at all. Provided that global warming, the end of cheap oil, and terrorists with nuclear weapons and dirty bombs don’t get us first.

"According to this report, over the last fifty years nuclear power has received 96% of federal energy subsidies."

The only possible way this statement could be anywhere near factual is to be selective in the data. "Research" which is begun with a pre-determined desired outcome [surprise] often produces the desired outcome. Arbitrarily assigning several billions per year for "accident insurance" coverage when no payments are ever actually made is one example. Ignoring the depletion allowance writeoffs for fossil (which should actually be taxed more heavily for making profits from a commons resource) is another. Even a proportion of military expenditures to support foreign imports.

However, perhaps it is more your post which is deliberately misleading than that diatribe from Marshall Goldberg.

You stated: "According to this report, over the last fifty years nuclear power has received 96% of federal energy subsidies. "

Which i presume you were attempting to paraphrase his statement: "Wind, solar and nuclear power received approximately $150 billion in cumulative Federal subsidies over roughly fifty years, some 95% of which supported nuclear power."

Those are two obviously different statements, yours being baldly incorrect at a cursory glance, theirs being simply a statement of meaningless information intended to mislead. Of course nuclear has recieved more subsidies than wind and solar, and you should be thankful for that every time you turn on a light switch and the power flows.

It all comes down to the profile of wind generation, vs. the profile of demand. If it's true that if wind's profile had a positive correlation with demand, than many of the author's points would be invalid. Indeed, with good correlation, simple turbines are what the wind power would tend to displace. However, this is not what I've been generally taught. I'll keep an open mind about this, but I was surprised by Mr. Greenbaum's statement about wind's positive correlation with demand. Perhaps this is true in California, but not in other parts of the country, I don't know. I'd been told that wind output is actually negatively correlated with demand (i.e., it puts out more power in times of low demand).

One cannot swiftly dismiss the author's point, as it is true that a combination of wind power and simple turbines as back up is no better than a combined-cycle plant running at 100%, with respect to both gas use and pollution. The whole question is whether that combination (wind farms plus simple turbines) would replace CCGTs. Once again, it all boils down to the generation and demand profiles, along with economic factors. It is all quite complicated, and it is hard to make simple statements and predictions on these issues. I'll say this much. It IS true that wind is appropriately considered as a fuel saver (only). It can not really be considered capacity, in the standard utility sense, in that you can't rely on it. You will have to have sufficient capacity to meet peak demand, assuming that the wind is not blowing, period.

For this reason, it is difficult to economically justify building more wind (rated) capacity than the overall capacity that is generated by gas in your portfolio. Having your wind generation, plus your coal and nuclear generation, exceed demand is a bad situation, since the fuel cost that your wind generation is saving is very low indeed. This economic "fratricide" situation is highly undesirable. (The windfarm is not amortizing any of its capital costs in that situation.) The situation is somewhat better if hydro is present, as you could let the reservoirs fill or empty, depending on whether the wind is blowing. This may increase the percentage that can be generated by wind, in hydro-heavy areas like the Pacific Northwest. Setting the hydro exception aside, the amount of demand (capacity) that is met by gas generally functions as a ceiling on the amount of wind capacity that can effectively by installed, due to the issues discussed above.

It is true that energy storage could increase the percentage of power that wind could effectively deliver, but I don't believe any economical means of large-scale energy storage has yet been devised (except for the symbiotic relationship with hydro that I discussed above). Much of the enthusiasm behind the hydrogen economy is due to the fact that wind could be used to generate H2 which could then be stored, thus allowing wind to get around its intermittantcy problem and thus allowing it to make a larger overall contribution.

While the wind generation and power demand profile issues are complicated, and vary by region, it is clear that a combination of wind turbines and gas plants could always be proposed as a baseload power plant. The gas plants do what is necessary to maintain rated capacity (i.e., they generate whatever power the windfarm doesn't). Now, the question is whether you would use a simple turbine or a combined cycle plant for the gas component. The "good" news is that at today's gas prices, I think they would still choose to use CCGT plants as the backup.

CCGT's capital cost ~$600/kW. whereas simple turbines are more like $200/kW. This difference in capital cost amounts to, at most, ~1 cent/kW-hr in the power price that needs to be charged (to amortize the capital), assuming baseload operation. At a gas cost of $6/MBTU, the CCGT plant's fuel cost would be ~4 cents/kW-hr, whereas the simple turbine would be ~6 cents/kW-hr. Thus, for baseload operation, the CCGT clearly has an advantage. Now, if you're operating the unit a faction of the time, the capital amortization costs roughly scale inversely with the capacity factor. As this simple example shows, the simple turbine would not be preferred until the capacity factor is under 50%. Both the author and his critics agree that the capacity factor for the windfarm is less than 50%. Thus, at current gas prices, CCGT units would be chosen as the backups for windfarms, even though they are running only part of the time. Indeed, the author's lower wind capacity factors makes the case for choosing CCGTs even stronger. I think CCGT's are responsive enough to handle the fluctuations.

Thus, CCGT's are more likely to be used as backup in a wind-heavy scenario. This is especial

Thus, CCGT's are more likely to be used as backup in a wind-heavy scenario. This is especially true given that we currently have ~100 GW of CCGT capacity that is not even being used, due to over-build. As these existing CCGT units' operating cost is cheaper than that of simple turbines, there is no reason why simple turbines should ever be used, no matter how occasional the need (i.e., simple turbines should not be used today, even in times of absolute peak demand).

For these reasons, I doubt the author's contention that wind power will result in an increase in the use of simple turbines. Instead, the effect of the wind will be to reduce gas use, and the resulting pollution, by ~30% ( or whatever wind's capacity factor is). Indeed, a large amount of wind may cause us to choose gas over coal, to soime extent, for new generation, due to the fact that some of this generation will only operate ~2/3 of the time (when the wind is not blowing), giving CCGT plants (with their lower capital costs) an advantage. While this will result in even more reduction in pollution (quite a bit more), it will have several negative effects. If increased use of wind results in choosing gas over coal (or nuclear), it will result in higher overall power costs, a reduction in our energy security (due to a large increase in imported gas), and will hasten the day when our gas resources run out.

Thus, whereas I don't believe that wind power will result in more pollution, it's possible that it will increase gas use, if it results in us choosing gas instead nuclear or coal for the remaining power generation. Since it is only "worth it" to displace gas or oil use with wind, a given wind power generation percentage virtually demands that an even larger percentage (roughly twice as much) be generated by gas (due to the ~1/3 capacity factor).

As Mr. Gould points out in his response to another current EP article, many "environmentalists" are actually advocating shutting down baseload (coal and nuclear) plants and replacing them with gas, simply because gas can respond better to the flucuating loads created by wind. Given the cost of gas (which will only go up), and the fact that we are running out of it in both Europe and North America (and will soon have to import most of it from Russia and the Middle East), this proposal is INSANE!!! Relying on gas for ~2/3 of new generation is insane, due to the high cost of gas and the energy security concerns, as well as the fact that gas is a precious, dwindling resource that should be saved for more important uses. Closing existing nuclear or coal plants is even more insane, since their going forward costs are only ~2 cents/kW-hr or less, which is vaslty lower than a new wind/gas plant (this, in addition to the energy security and resource use considerations).

The intermittantcy issue is a serious one that can not be overlooked. For the above reasons, even most advocates of wind power only believe that it may be able to make up ~15% of overall generation. I agree with Mr. Powers. I support both nuclear and renewable energy. Both will have a role to play in the future, and neither is able to do the job alone. The only thing I'm against is conventional (as opposed to clean) coal plants, as all studies show that their external costs are vastly larger than any other source. It's use should be minimized, although I accept some, albiet reduced, role for clean coal technology. In order to reduce coal use as much as possible, ALL alternatives need to be fully supported, and developed to the maximum practical extent.

Despite what was said in this (unfortunate) article, most of us nuclear proponents are also very supportive of renewables. The only limit (or qualification) of that support is that we do not believe that renewables alone can handle all future power needs. Most of us support nuclear because we are well aware of the horrible effects of fossil fuels, coal in particular. We believe that we will be able to reduce fossil fuel (or coal) use to a much greater degree if we include nuclear in the mix of alternatives, as opposed to insisting on only conservation or renewables (and perhaps gas). Global warming is one example. If we truly wish to significantly reduce CO2 emissions, we will need to fully support ALL non-fossil sources, including nuclear. We can't afford to play favorites, or let the "perfect" get in the way of the "much better".

It's a shame that we can't get past the nuclear VERSUS renewables argument. How about BOTH. Because, we're gonna need both!! It's fossil fuels that are the problem, both environmentally, and with respect to energy security. And, with respect to all the arguments about subsidies, etc.., we need to not think about the past (indeed, the distant past), and start thinking about the future. The discussions about the past are neither helpful or relevant.

The author's main point specifically concerned the use of a renewable portfolio standard (RPS), with a goal of ~20%. His point was that it could possibly increase pollution and/or gas use.

My first reaction to this is that this whole issue could be addressed much better through the use of a more elegant policy instrument, namely pollution taxes. An alternative (though less "perfect") alternative is a cap-and-trade system. If we had such a policy in place, we wouldn't need to be having this argument. It would be left to industry to figure out what approach would most reduce pollution. Under this system, where they are taxed on overall emissions, they would have every incentive to take the approach that minimizes emissions, and believe me, they will be able to accurately (and honestly) figure out what is best for their bottom line. That's the most beautiful part of all about this (pollution tax) system. Nobody has any incentives to be dishonest about anything.

Under this approach, if the author is right, and windfarms actually increase pollution, as well as gas use, then they will not build any windfarms. However, on the other hand, if windfarms actually DO reduce pollution, they will figure it out, and they will indeed build them. The great part is that we do not have to argue about this, or figure it out, in order to decide upon the correct policy. The correct policy is simple, elegant, and obvious. You are taxed on the pollution you emit, based upon SCIENTIFIC analyses that determine the negative effects (public health, economic, environmental, etc...) of each ton of that pollutant. Economic effects like the costs of gas, versus other fuels (like coal and uranium) are also automatically accounted for. We could even add a tax on foreign fuels to reflect foreign energy dependence concerns, thus automatically acounting for these issues. It would then all come out in the economic wash, with utilities just doing whatever's best for their bottom line, under those rules.

A cap-and-trade system would work in a similar fashion, although not quite as well. One of the author's main points is that the RPS may not be the best approach, and may involve pernicious effects and unintended consequences. This is a point on which I intend to agree. I believe that pollution taxes and/or cap-and-trade systems are ALWAYS the superior approach to attain any objective, such as pollution reduction, and that there are few intellectual arguments that can justify the use of the RPS instead. It basically involves picking winners, and using a rigid command and control approach to deciding the best path forward, instead of utilizing the forces of the free market to determine the most efficient and economic means to attain any given objective.

Consider the following. There are six ways to reduce air pollution:

1) Install more pollution controls 2) Replace old, dirty, inefficient fossil plants with new, clean, efficient fossil plants 3) Conserve energy 4) Fuel switch (from coal to gas) 5) Increase nuclear generation (to replace fossil) 6) Increase renewable generation (to replace fossil)

Note that five of these six options (all but #1) also serve to reduce CO2 emissions.

Here's the main problem. An RPS encourages one, and ONLY one, of the above options. The other two policies, pollution taxes or cap-and-trade, encourage ALL of the above approaches. Not only that, but they rely on the free market to decide what mixture of the above approaches yields the maximum pollution (or CO2) reduction for the lowest cost.

Pollution taxes, or cap-and-trade, at least, are the best approaches to use, for CO2 reduction, as well as for all pollution reduction policies. To hell with the RPS!! Heaven forbid that an energy source be judged on its actual merits, as opposed to its political popularity! And one more thing, who gets to decide which energy sources get to be categorized as "renewable" (i.e., which sources get to wear that "blessed" label)? And no, this is not obvious. Right now we read about humorous arguments over whether various sources should be called renewable, with some actually (and tragically) arguing that dirty sources like trash and waste coal piles should qualify as renewable sources.

It all gets very political, very quick, of course. How sources are treated and categorized will become a matter of political payoff, and scoring political points (with environmental groups, or economic interests, etc...) as opposed to doing what will best accomplish our REAL objectives (i.e., reduced pollution, CO2 emissions, and foreign energy use, etc...). This is just the thing that we need to avoid, and the more elegant policies (tax or cap-and-trade) automatically do so. You simply define a real, tangible, and meaningfull goal (i.e., what you are REALLY after, such as, I wan't to discourage or reduce the emissions of pollutant "X", or, I want

Seriously, the more I look at it, the more I'm convinced of what the RPS is really all about. It is about having policy be based on a purely political calculation, as opposed to a scientific or economic calculation. In large numbers of states, I'm seeing RPS's being put into place, while at the same time I'm seeing conventional coal plants being built, instead of clean coal plants, or gas or nuclear plants. Retrofits of existing plants with the latest pollution controls is not being required either. These options are rejected as being "too expensive", while the RPS requires the use of even more expensive energy options. The bottom line is that these other methods would have resulted more pollution reduction for less cost.

It seems that the real objective was to hand "each side" their pound of political red meat, as opposed to minimizing pollution. The RPS was red meat for the environmental groups, whereas allowing the use of conventional (dirty) coal plants for most new capacity was what the utilities wanted. Thus, what you have is continued use, and construction, of dirty, conventional coal plants (the lowest economic cost, environment be damned option) with a few windmills sprinkled around for political window dressing. How sad. How utterly sad. The real "economy" here is the political economics of what's most likely to get you re-elected.

In answer to some people's posts, ALL waste management and plant decomissioning costs are fully included in the ~1.75 cent/kW-hr nuclear operating costs. This includes all steps required to meet the (ridiculous) demands of negligible public exposures, over all time. And no, the govt. provides absolutely no help, and no subsidies, with respect to any of this. Meanwhile fossil fuels like coal are allowed to routinely emit millions of tons of pollutants, cause ~24,000 premature deaths every year, and be the single leading cause of CO2 emissions, etc.....

Concerning nuclear subsidies, alot of the things being quoted (from RMI, etc..) are misleading or completely wrong. First of all it's in the distant past. Note that they always quote from 1948, or something like that. The fact is, while nuclear DID receive substantial help in its developmental years, the subsidies, and govt. research funding, has drastically dropped, and the level of support has been negligible for the last 20 years or so. The anti's will conveniently never mention this. One has to ask about the relevance, to the current discussion, of subsidies that went away over 20 year's ago.

One must ask them, "what, exactly, do you wan't?" They would likely say that they want nuclear subsidies to go away, or at least be much smaller than renewables subsidies. Well, we can clearly respond, "we've already done that!, you're wish has already been granted!" Right now (and for the last 10-20 years) nuclear power receives no direct operating subsidies, and nuclear research funding is a much smaller than that given to conservation, fossil fuels, or renewables. What more could they want? For some time, nuclear has been the ONLY energy source that receives virtually no govt. help. As Mr. Gould points out, the new energy bill is absolutely no exception to this. As the bill stands right now, both fossil and renewable sources receive large amounts of goodies, while nuclear receives nothing of any real value.

Another point that needs to be made concerns the statements made about nuclear program funding in the 90's versus other sources. The issue, and problem, here concerns the titles used for various govt. agencies and programs. There is a large title in the budget that is euphemistically titled "Nuclear Energy" (or perhaps "Nuclear Energy R&D"). Examination of this budget title shows that the vast majority of the funding goes to nuclear WEAPONS site cleanup activities. This has absolutely nothing to do with commercial nuclear power. It is criminal how the DOE is organized, and how they would use titles like that. Is it literally one of their objectives to give (false) ammunition to enemies of the nuclear power industry? If I were president, the first thing I would do, the very first afternoon I was in office, would be draft an executive order to move all nuclear weapons related activities (including all cleanup activities) from the DOE to the DOD where it freakin belongs!! At an absolute minimum, a section of the budget that mainly includes weapons site cleanup activities would not be titled "Nuclear Energy R&D". What utter BS! My God, who comes up with this stuff!!

Getting to the point. I KNOW that the $600+ million figure quoted by Mr. Fleming is based on the entire budget for the "Nuclear Energy R&D" title. I've checked the budgets myself. The fact is that govt. research funding for projects of any real benefit to commercial nuclear power, direct or indirect, have gotten less than $100 million for the last several years. This is up from virtually zero in the 1990s. In the late 90's Clinton actually zeroed out all commerical nuclear power research. He specifically stated this in a State of the Union address (do you remember it??). Recent projects include the advanced nuclear plant programs, along with the advanced fuel cycle initiative (which actually is of little use to the industry anyway, for the foreseeable future).

To summarize, nuclear has gotten less than $100 million in govt. research funding for the last 20 years or so. Also, this research funding is the ONLY support nuclear has gotten. Nuclear has not received any subsidies that reduce operation costs, directly or indirectly. By contrast, fossil fuels and conservation programs received ~$600 million in govt. research funding this year, and renewable energy received ~$350 million. On top of this, these sources receive huge direct operating subsidies. Wind gets the 1.8 cent/kW-hr production tax credit. Solar gets a similar federal credit, with state programs covering half the cost of a PV system, which translates into an over 10 cent credit!! Fossil fuels are subsidized in too many ways to count or describe. Not only are all aspects of fossil mining and production subsidized, but their external (pollution) costs, which run as high as 7 cents/kW-hr (for coal) are completely ignored and forgiven. Under a

....Under a pollution tax system, such as I advocate, fossil fuels would do a hell of a lot worse, believe me! Pipelines are also subsidized, and of course we can't forget the huge military necessary to protect our oil (and soon gas) supplies!

As I said before, things that happened 20 years or more ago are irrelevant to this discussion. It is about current and future policy. The fact is that nuclear has been, by far, the least subsidized energy source for quite some time. You want renewables to receive far more support than nuclear from now on? Already done!! That is current policy. And hey, if you want to increase renewables research even more, you'll get no argument from me. I would argue that the PTC is enough however, and indeed should be eventually phased out. Indeed, if I'm to believe Mr. Bradley's cost figures, the PTC shouldn't be needed even now. If that were the case, I wonder, why is everything at a standstill now that the PTC is in limbo?

One final point, the 10 cent/kW-hr cost figure for nuclear is clearly BS. I'm sure that what this is based on is the levelized cost of power from the "most recent" nuclear plants that came on line during that period, i.e., the late '90s. After all, these are the "most recent" examples for nuclear, and therefore the most accurate measure of its cost, right? Wrong!! What breathtaking intellectual dishonesty!! All of the plants were ordered at about the same time. Thus, the plants that finally came on line in the '90s are the stragglers, i.e., the ones most delayed by various issues, including the various legal antics of the anti-nukes. For these reasons, these are the 2 or 3 plants that have the very highest overall costs. The costs of most of the other ~100 plants are vastly lower!

Despite the (tragic) delays and issues for the first generation of nuclear construction, the average overall costs for nuclear electricity in the US is more like 6 cents. And even here, I have to ask, what is this "levelized" cost based on? What payback period? These plants are paid off now, mostly, and the rest of their 60-year lives will be pure gravy, with a total power cost of only 1.75 cents/kW-hr or less. Thus, nuclear plants are more expensive up front, and result in higher power costs for awhile, but they result in lower costs (and more stability in costs) farther down the road. Of note is the fact that Commonwealth Edison's rates (~80% nuclear) have fallen below the national average, after being above the average for many years after contruction of the plants. Their rates will fall even further below the national average over the remaining ~40 years of these plants lives, and as gas prices continue to increase.

Also, several plants have been constructed recently overseas (in the Far East), on budget and on schedule, at costs which translate into ~5 cents/kW-hr (under any reasonable financing terms or interest rate). Today, plants are designed down to the last detail before construction, and in most cases we have actual experience with a specific, detailed design. We are much better at accurately estimating the cost. With the new advanced plants that will be built in the future, detailed and sophisticated estimates of contruction costs predict an overall power cost that is closer to 4 cents/kW-hr, which is already cheaper than gas (at $6/MBTU) and is even competative with conventional coal. Excessive perceptions of financial risk on Wall St, are all that is keeping the industry back.

The fact of the matter is, in today's more deregulated market, if nuclear plants are not economical, they won't be built, period. It's not as though they receive any govt. help...... Thus, why are we wasting our breath on this "issue". The issue is dead.

On the cost of power, Mr. Hopf’s estimate of 6 cents/kWh for nuclear power is about right, according to the study (2003) at http://web.mit.edu/nuclearpower/ , which indicates a cost of 6.7 cents (LWR). It says that, in deregulated markets, nuclear power is not now cost competitive with coal or natural gas CCGT.

The authors of this study make several conclusions: nuclear power should not be dismissed if global warming is to be taken seriously, but a radically different nuclear R&D program is needed; much work remains to be done to reduce cost, improve safety, stop proliferation and provide safe methods of waste disposal; only the once-through cycle has a chance of becoming cost competitive; if the R&D program outlined in the study were followed, it would probably take at least ten years to put nuclear power on a competitive footing. Without the requirement to reduce carbon emissions, nuclear power may never become competitive. However, there is no question that drastic reductions in carbon emissions must be achieved within the next ten years.

Concerning safety, we must not forget what happened at the Davis-Besse plant two years ago. The owners and operators were extremely careless. Their first priority was profit, not safety. They ignored the clear evidence, and the repeated warnings of a plant engineer, that boric acid was eating a hole in the reactor vessel. The NRC was also asleep at the switch. After the magnitude of the problem was finally recognized, and a monumental disaster narrowly averted, a few heads rolled and we were assured that safety training and procedures were improved.

Were these reforms enough, even if they were fully implemented? The paper on Price-Anderson provides valuable information on this question. On that evidence and common sense, I doubt that it would be possible to realize the safety regime proposed in the MIT study. It would rely, as it must, on fallible and unreliable human beings. Furthermore, part of the safety requirement is effective plant security. We do not have it yet, not by a long shot. Nuclear plants are regularly invaded by teams of government agents who are sent out to test the defenses, even when the plant operators know they are coming.

I doubt that the MIT anti-proliferation plan could be realized either. It would depend on a responsible, effective international police agency, but how is it to be formed and invested with the necessary coercive power? If I remember correctly, the best agency we have been able to form so far, the IAEA, completely missed the Pakistani, Iranian and Libyan nuclear weapons programs, and probably that of the North Koreans also. The United States, possessing the greatest military power that ever existed, can’t even manage to control Iraq (not that we should), let alone the world. The Europeans can’t agree on how to cooperate among themselves, let alone with us. North Korea has the bomb and there is nothing we can do about it. Well, I must limit my comments, but I think you will understand my point.

To summarize, it appears to me that not even a blue-ribbon MIT panel can figure out how to make the dream of nuclear power come true. For the final nail in the coffin, we have the following study published late last year (Mr. Hopf, please sit down and pour yourself a shot of your favorite potion before you read it):

http://www.oprit.rug.nl/deenen/

In this remarkable study, the authors have made a convincing analysis of a surprising problem with nuclear power. I think I can already hear the sound of gaskets blowing. The most important message that the study delivers is this:

“Since we know now that the fossil fuel reserves may only be used sparingly because of the danger of global warming, it is essential that the public realize that the future of our civilization depends critically on reducing the use of energy drastically and rapidly. There is really no alternative.”

Anit-nukes need to wake up on the issue of non-proliferation. It's too late, people. With absolutely no regard to any action of the US beyond direct military intervention real or threatened, the rest of the world is going to carry on doing whatever it chooses regarding nuclear weapons and power. I'm not saying that is a good thing, but it is reality. We are not in a situation as in 1946 where one could dream of controlling the disemination of the knowledge, technology etc. That debate is dead. Has been for decades. Stuff it.

Whatever number of nuclear power reactors the US chooses to employ in its generation mix will have simply zero effect on the international nuclear weapons situation. Period. Zilch. Nada. No further discussion.

If you have read the OPRIT study, you will understand that nuclear power is not a solution to global warming. There is simply no longer any valid argument in favor of nuclear power. It fails on cost and safety, it can't reduce carbon emissions, and we can't prevent it from putting nuclear weapons into the hands of people who are likely to use them.

Our energy problem is far worse than most of us think it is. To start turning this situation around, I propose that we ration gasoline. Not by price, however. That would not be fair. Gasoline is a matter of life and death to us in our present predicament. It is like liberty. Everyone must receive an equal ration, so long as they have earned it. The cost would be two years of national service. No national service, no gas, and no voting either. Let people drive what they want, but they must do it on a gallon a day to start with. This amount would be reduced as world oil supplies are depleted. For our electrical power, we ought to convert the automobile plants into wind turbine plants and solar panel plants. On trash day, we ought to make everyone explain to his neighbors why he is throwing out that perfectly good chest of drawers. "It didn't match your new paint scheme, Mr. Jones? I sentence you to twenty lashes, and put that chest of drawers back in the house." Someday soon we will be forced to understand the necessity of such measures.

The least environmental damage occurs when society advances far enough to be able to afford to address the significant environmental problems – which are NOT the ones that are usually trumpeted with such vigor. Such advances occur – as they have anytime in the last 200 years - only in those societies which are able to exploit energy to the most full: the more energy the more social advancement and improved health and life expectancy, the more efficient the use of energy, and the less the overall environmental impact. Eventually we may be able to reduce our energy use, but we had better do it for all of the right technological reasons, and not because some hair-shirt zealot says that we must.

In addition, how you can honestly suggest that the adoption of nuclear power is NOT conducive to a reduction of carbon dioxide emissions, beggars belief. You sound like a mouthpiece for the Rocky Mountain Institute or the Sierra Club among others. Assume for just a few moments that society is increasingly electrical (as it now is in our part of the world) and that we had evolved to an almost totally nuclear society, and displaced most coal, oil, natural gas and gasoline, in favor of electrical heat, electric or hydrogen cars, or whatever. Unless you engage in Orwellian doublespeak, how does that change NOT reduce carbon dioxide emissions?

I read the various reports you suggested might inform us, and found the one from REPP to be what I would expect – self serving and very selective of what they would like anyone to believe. What I have always found to be most telling, is that those who cannot promote or defend their own particular product on its merits, usually engage in knocking the alternatives in every way possible, even to the extent of using half-truths or worse, and very careful selection of information for public consumption.

Despite the qualifications and backgrounds of the writers on the oprit site, I found their information and assumptions highly selective and frustratingly ill-quantified, as well as ill informed considering their backgrounds. My second article on this site showed that the accessible uranium and thorium resources on this planet are useable for many millions of years using existing and well-understood chemical and nuclear technology. http://www.energypulse.net/centers/article/article_display.cfm?a_id=374 I found it strange that your ‘qualified’ authors do not understand these subjects better. Again, my comment applies that whose who are able to do so, usually promote what is possible, and those who are NOT able, just knock the alternatives as hard as they can, rather than presenting a perspective view of them all and discovering the one (or several) that is better than the others.

I found the Cato article to be a similar questionably-biased piece of work. Usually I see much better quality from Cato, and I hate to knock renewables (excluding hydro) any more than I already have, and do (too dilute, too intermittent, too expensive, too unreliable: all true), but I can refer our readers to policy articles 280 and 422 on the Cato site which provide some most pertinent and accurate information on renewables.

Your significantly blinkered arguments about nuclear safety indicate that in common with the rest of your arguments, you ignore what you do not like and select what you do. If that bias were driven by rational science and a truly deeper knowledge, it would be understandable. Unfortunately, it isn’t.

I refer you to the figures provided by the Paul Scherrer Institute in Switzerland, and that I have quoted in the past in response to others like yourself who wage highly selective emotional onslaughts because they cannot, or will not, understand relative risks. http://www.energypulse.net/centers/article/article_display.cfm?a_id=498 Data from the Paul-Scherrer Institute in Switzerland for 1969 to 1996, showing relative human fatalities from 4290 energy-related accidents in commercial facilities, indicate that for each terra-watt-year of energy use (the world uses about 13 TW of primary energy each year at this time), the following

Nuclear Power 8 Natural Gas 85 Coal 342 Oil 418 Hydro 884 LPG 3280

Please tell me what you cannot understand about these very simple relative risk numbers from a well-respected source.

http://www.oprit.rug.nl/deenen/

"In this remarkable study" indeed. There is a very clear path to proof that this stuff is pure bunk, as follows.

1) Operators of nuclear power plants are in the business of selling net energy out.

2) If the energy input to the fuel enrichment of PWR's and BWR's were anywhere near significant to the net out of the cycle, then that would give the CANDU6 HPWR an enormous economic advantage in the international marketplace for reactors, since IT DOESN't USE ENRICHED FUEL, simply natural uranium directly as mined.

3) Since there is no evidence of this factor being anywhere near significant to purchase decisions of e.g. China, Korea, Albania etc. or in considerations for future styles of reactors anywhere else, it can be assumed that the FUEL ENRICHMENT ENERGY INPUTS MUST NOT BE SIGNIFICANT TO THE NET ENERGY OUTPUT.

(Note: In fact, the CANDU group is presently designing a new reactor to employ slightly enriched uranium simply in order to reduce the size of the calandria for economix reasons)

The argument's bunk is out.

GF: "Mr. Hopf summarily rejects the conclusions of the REPP study."

Well, not entirely (or necessarily). I'm just trying to say (and clarify) that most (90%) of the govt. funding under the "Nuclear Energy R&D" budget titles is actually related to the weapons sites, and their cleanup, or other unrelated areas like fusion and high-energy physics. I am relatively confident that these (anti-nuclear) studies ignored that fact when the came up with their "subsidy" numbers. I'm also pointing out that most of these subsidies occurred in the late '40s through the '60s. (Note that the 1948 date is conveniently chosen for these analyses.)

I acknowledge the fact that nuclear received a lot of support during its early development. However, I think our discussions here are primarily about present and future policy, (or at least they should be). At present, the only govt. support nuclear receives is the Generation IV advanced reactor program, the Advanced Fuel Cycle Initiative, and the Nuclear Power 2010 program. These are the only programs that are of any real benefit to the industry. These programs amount to ~$100 million per year, whereas the fossil and conservation department gets $600 million, and renewables get $320 million.

The only other thing that could possibly be called a subsidy is Price-Anderson, and even the studies often quoted by anti-nukes show that this "subsidy" only corresponds to ~0.04-0.4 cents/kW-hr. This is tiny compared to the external costs of fossil fuels (associated with pollution and its effects) which are over 5 cents/kW-hr for coal, for example.

GF: "On the cost of power, Mr. Hopf’s estimate of 6 cents/kWh for nuclear power is about right, according to the study (2003) at http://web.mit.edu/nuclearpower/ , which indicates a cost of 6.7 cents (LWR). It says that, in deregulated markets, nuclear power is not now cost competitive with coal or natural gas CCGT."

Well, be careful, this isn't quite right. The 6 cent figure I quoted is the overall average cost (including capital) for the last generation of nuclear plants, including all the delays and cost overruns and all. The 6.7 cent figure quoted by the MIT study is their estimate for future plants. And note that the statement on gas appears to be dated. At the current price of gas ($6/MBTU, plus more for distribution to the plant site), the overall cost of CCGT power is pretty close to the 6.7 cent figure. In the future, I don't see gas going down. In fact, I only see it going up.

Concerning the 6.7 cent/kW-hr figure, it is based on a very conservative capital cost estimate of $2,200/kW, along with extremely harsh financing terms (i.e., a very short demanded payback time, and an excessively high required rate of return). These financial terms can dramatically affect the resulting "power price", even for plants with the same real costs (i.e., overnight captial cost and operating costs). If you did something simple like assume that one could get a long-term loan for some high (but still reasonable) interest rate of say 10%, the resulting calculated cost would be much lower than this, and nuclear would already be close to coal, and be far ahead of gas.

Also note that the only reason why coal and gas are currently cheaper is that their external costs (i.e., pollution) are completely forgiven. Nuclear's external costs are minimal, as is shown by all studies (e.g., the European Commission's Extern-E study). Nuclear basically is not allowed to pollute, or have any external costs. The public has zero tolerance for nuclear external costs. As I said above, the REAL cost of coal is higher by over 5 cents, more than enough to make it wholly uncompetative with nuclear. One final note, under ANY system where we are trying to reduce CO2 emissions, the tax on CO2 will have to be such that non-emitting sources are cheaper than coal (and gas to a lesser extent). Under any such regime, nuclear will become cheaper than coal (since it will have to be).

The nuclear industry is adamant that the capital cost figures assumed for new plants in the MIT study are far too high. The industry believes that it will be able to achieve $1,300-1,500/kW for the first few plants, and $1,000-1,200/kW for downstream plants. This would make nuclear even cheaper than coal, even without any of the much harsher environmental requirements that are sure to come out in the future. The industry has literal experience overseas (in the Far East) building plants, on budget and on schedule, for costs of ~$1,500/kW or less, which translates into ~5 cents/kW-hr. The new, advanced designs are thought to be even cheaper, and would result in a power cost of ~4 cents/kW-hr. I've heard from the author's of the MIT report personally (at conferences, etc..). They acknowledge that the $2,200 figure is conservative, and have stated that they used it because "Wall St. insisted that the conservative figure be used". They also a

.....They also agreed that the estimates for significantly lower capital costs (for the new designs) are very "plausible", but they need to be demonstrated.

Also note that the MIT study's official policy recommendation is that the first ~6000 MW of new nuclear capacity be given a 1.8 cent/kW-hr production tax credit to get the ball rolling. Once the first few plants are built, and the costs and schedules are demonstrated, the perceived financial risk will be greatly reduced, further plants will be able to get funding on much more favorable terms, and the PTC will no longer be needed.

GF: "....it would probably take at least ten years to put nuclear power on a competitive footing. Without the requirement to reduce carbon emissions, nuclear power may never become competitive. However, there is no question that drastic reductions in carbon emissions must be achieved within the next ten years."

Nuclear is competative with other sources of energy RIGHT NOW, if their external costs are considered. The only reason fossil fuels are currently cheaper is that they are getting a free ride on the massive amounts of pollution they emit. And this is true even if CO2 emissions (global warming) is not considered. A recent study showed that coal plant emissions, in the US alone, cause 24,000 premature deaths every single year!! Can you believe that! This is far worse than having a Chernobyl event every singe year. And yet this is tolerated. Can you even imagine if nuclear were to......

Thus, nuclear does not need a carbon emissions reduction requirement to be competative, it only needs ANY type of accounting for external costs, and pollution in general. The only thing it can't compete with right now is dirty, conventional coal. It can already compete with gas on raw cost (w/o external costs added), and "clean coal" plants are just as expensive as nuclear. Conversely, however, if we ever DO have CO2 emissions limits, fossil fuels will be completely blown away, and nuclear's future as the dominant baseload generator will be assured.

I'll say this though. There will NOT be any significant nuclear additions in the next 10 years, given the path that the industry is currently on (their plans, etc...). Under the Nuclear Power 2010 program, they are planning on starting construction on 2 to 4 new plants, which may be on line as early as 2014. Thus, it's true that nuclear will not be able create a "drastic reduction in CO2 emissions" in the next 10 years. Alas, NOTHING will. In fact, we're going the wrong way. There are ~100 new coal plants on order, since renewables can only do so much (only a little, actually), and gas has gotten significantly more expensive than coal. Most new capacity in the next 10 years will be pure carbon. Great huh?

GF: "After the magnitude of the problem was finally recognized, and a monumental disaster narrowly averted...." (concerning Davis Besse)

Well no, I definitely would not call it a "monumental" disaster, and it was not narrowly averted. NRC just came out with an analysis which showed that even the stainless steel vessel cladding alone would have been enough to withstand the pressure, and would have lasted at least the 10-13 more months until the next scheduled outage. Also, if the cladding ruptured, and the water/steam vented out, we would have had an event about as serious as TMI, if that. TMI being an event that killed noone. This is just one more "horror" story about a nuclear plant event that killed, well, noone. The real facts remain the same. The US nuclear power industry has never emitted any significant amount of pollution, has never had any measurable public health effect, and has never killed a member of the public, over its entire 40-year history. This, in contrast to 24,000 deaths every year, under routine operation, for coal. GF: "....it would probably take at least ten years to put nuclear power on a competitive footing. Without the requirement to reduce carbon emissions, nuclear power may never become competitive. However, there is no question that drastic reductions in carbon emissions must be achieved within the next ten years."

Nuclear is competative with other sources of energy RIGHT NOW, if their external costs are considered.

(Sorry for the screw up last post, please ignore the last 2.5 paragraphs, after the GF:'....)

I'll try it one comment at a time......

GF: It would rely, as it must, on fallible and unreliable human beings. Furthermore, part of the safety requirement is effective plant security. We do not have it yet, not by a long shot."

Nuclear's "acceptability" does NOT rely on infallible equipment or human beings. The risks do not have to be zero in order for it to be acceptable. They just have to be as low, or lower, than other sources of energy. I get very frustrated with this zero risk notion. As is shown by the statistics given above (comparisons to coal, etc...) it is already clear than nuclear's overall risks are already orders of magnitude lower than those of fossil fuels. ALL scientific studies on the matter (such as the EC's Extern-E study) agree on this. This negligible risk has already been demonstrated by Western nuclear power, with its spotless safety record, over a very long history. We don't need any more proof.

Concerning security, it should be noted that nuclear power plants are the only civilian sites that are even required to have such drills, even though there are many other types of sites (e.g., chemical plants and LNG terminals) that are far more vulnerable (both physically and in terms of security arrangements) and which also have a far greater potential consequences. Yes, that's right. EPA states that there are ~100 or more chemical facilities that could kill as many as a million people in the event of a successful attack, and their physical protection (such as the nuclear plant contaiment, etc...) is much weaker than nuclear plants. And we're talking immediate, clear deaths, not hypothetical deaths associated with tiny cancer rate increases from low-level radiation exposures, etc... The nuclear industry has done more than any other in terms of secutiry, and are our more protected civilian sites. When you estimate and sum up all of our sources of terrorism risk in this country (by multiplying consequences times the probability of a successful attack), you find that nuclear power plants do not contribute significantly to our overall vulnerability.

GF: "I doubt that the MIT anti-proliferation plan could be realized either.........but I think you will understand my point."

No, I don't understand your point. None of the issues you discussed have anything to do with commericial nuclear power in developed countries like the US, or the number of those plants. I'm with Len on this one. Adding more once-through fuel cycle nuclear plants in the US has absolutely no impact at all on the proliferation issue (i.e., the speed at which rogue nations obtain nuclear weapons, etc...).

None of the examples you discussed had anything to do with US (or European) nuclear power. None of these programs were the source of the fissile material for any cases of proliferation. This is because stealing spent fuel from a developed nation, and processing it for the plutonium, is the single most difficult (and silly) means of obtaining fissile material that anyone has ever dreamed of. Spent fuel is less valuable than the uranium ore in the ground in these countries, all things considered. All of these countries smuggled the technology to enrich uranium, and used it to enrich their own uranium ore. Either that, or they built their own reactors. These avenues are the ones that lead to proliferation. An outright nuclear bazaar in Russia, N. Korea, or Pakistan are another significant risk. The fact is that the world lacks the political will to do anything even when a country like Iran is abviously developing nuclear weapons right under our nose. THAT is the problem (not civilian nuclear plants in developed countries). Until we develop some backbone, proliferation is inevitable. It is anyway. This is just a fact of life, frankly.

The authors of the MIT studied estimated that 20% of the new nuclear capacity in their high-nuclear-growth scenarios would be in new countries that do not currently have nuclear plants. Believe it or not, I'm flexible, and willing to negotiate on this point. I'm willing to settle for the 80% growth in the current nuclear countries. I would be willing to entertain a policy of no nuclear power for nations that do not currently have it (with a few large-nation exceptions such as Australia, or any European country, etc....). I also support the recent proposed policy of having no fuel cycle facilities in nations that do not already have them. And of course getting all the high-enriched uranium out of all those research reactors is the highest priority. These steps are sufficient to eliminate the overwhelming majority of proliferation risk. Once again, having more or less reactors in nations that already have them, especially if they are once-through, has aboslutely no impact on proliferation risk.

GF: To summarize, it appears to me that not even a blue-ribbon MIT panel can figure out how to make the dream of nuclear power come true."

That's not true. All we need is for fossil fuels (especially coal) to be held accountable for their external costs (pollution), OR we need to codify a goal/requirements that we reduce CO2 emissions. Either one of these policies would make nuclear the baseload power source of choice in the future.

This reminds me of another gloom-and-doom link that was posted by a person on the John Kerry website. This site said that as early as 2030, the energy required to mine our remaining coal reserves would be twice the energy content of the extracted coal (thus utterly ending coal as a viable energy source). Thus, you may have HEARD that we had a ~250-year supply of coal, but it was really all a fantasy.... Much as I hate coal, even I can't believe this, not even for a second. This same site went on do describe how all of the alternatives to oil will not be sufficient, and how the collapse of civilization is coming, etc... Yet even this site did not discuss this specific problem of uranium requiring more energy that it takes to mine it. It merely stuck to the more common concept of economically recoverable reserves.

Anyway, the arguments sound similar here. And yet, as with the coal case, nobody in the industry seems to be even mildly concerned, even though this is completely central to their livelihood.

I'll also note that even this study states that, given new high-grade reserves that are likely to be found, the nuclear industry could probably provide all of the world's power for "only" a few decades, assuming the once-through fuel cycle. I don't know about some of you, but this is all I ever had in mind for the total collective generation from fission anyway (certainly from once-through fission). The highest fraction of total power nuclear would ever attain is ~50%. Thus, we are already talking about well over 50 years. By the latter part of this century, I expect nuclear power to be trailing off, as it is replaced by fusion or renewables, and the like. Either that or a move to breeders.....

Let me start with the energy input for enrichment, since it is easy. Up until now, we supplied all our enrichment services with the old, grossly inefficicent gas diffusion process. These plants required a ~500 MW power plant dedicated to their operations (at most ~1000 MW). Our nuclear fleet generates ~100 GW. Thus, even with the old technology, energy input from enrichment is less than 1% of the power output. Also, these plants will soon be replaced by gas centrifuge plants which consume only ~5% as much electricity. Thus, in the future, the power input term from enrichment will only be ~0.05% of power output by the nuclear plants.

Concerning the mining term, at least the cited study "admits" that the energy input terms are negligible for today's high-grade ores. In some ways this makes it harder to argue. I could reference several studies and analyses that make it clear that the mining and milling of uranium does not involve significant energy input (fossil or otherwise). These include calculations of net CO2 (and other emissions) from the entire nuclear fuel cycle (which would include all mining inputs), as well arguments about uranium costs, and how energy inputs could not be significant, given that the uranium ore costs only amount to ~0.1 cents/kW-hr, whereas the power costs almost 2 cents (~4 cents including capital). But alas, any such studies would be based on CURRENT energy inputs from (high-grade) uranium mining.

Instead, this study "admits" that everything is fine now, but assures us that disaster is just around the corner. This makes it much harder to present decisive evidence showing that their analysis is false. The analysis then uses pessimistic estimates of remaining high-grade ores, and largely neglects the amount of high-grade ore that remains to be discovered. Then it makes pessimistic assumptions about massively more energy being required for lower-grade ores, without giving a solid basis. It is not intuitive to me that energy use for extracting ores is such a strong function of uranium concentration. And of course, future technology advances in mining are ignored.

As I've stated elsewhere, whereas we've thoroughly scanned every nook and cranny of this planet for oil and gas, we have barely even begun to explore for uranium, since we have not needed to. After only a relatively small amount of effort, we found all the uranium we needed, most of our supply coming from a handful of mother-lode sites. The supplies were so ample that the price of uranium ore crashed to extremely low levels, especially after we decided to take the enriched uranium from decommissioned warheads and use it to provide half of all our nuclear fuel. At the price that existed over the last 10-20 years, absolutely no uranium exploration was performed, as even the existing mines could barely get by. When the price of uranium ore goes up significantly, we will see a significant exploration effort, and our known reserves of uranium ore (even higher-grade ore) will increase significantly, believe me. And since the cost of ore only corresponds to ~0.1 cents/kW-hr, nuclear power can afford a huge increase in ore cost. Don't put any

.......Don't put any credence at all in current "estimates" of total recoverable uranium reserves.

A reference I have on potential uranium resources (Deffyes and MacGregor) shows that the total uranium reserves increases by over a factor of 300 if you add sources with uranium concentrations as low as 10% of that present in today's high-grade ores. The same reference, along with 3 others, shows that at a price of $130/kg (vs. today's price of ~$40), the total recoverable uranium resource 3 to 20 times our current "recoverable" estimate of 5 million tons (which is enough to supply the current world usage for 50 years). Thus, at $130/kg, we have enough U to supply the world, at today's consumption levels for 150-1000 years.

Of course, if we wish to expand nuclear's share of total world primary energy from ~8% to say 30%, and also account for expected growth in overall energy demand, we would have to increase nuclear's output by a factor of 7-8. This would reduce the above lifespan to 20-130 years. Note, however, that an ore price of $130/kg would only add ~0.2-0.25 cents/kW-hr to the overall cost of nuclear electricity. If I extrapolate the data given in these references to a uranium ore cost of $450/kg, which is enough to increase the cost by 1.0 cents/kW-hr, I get a range of 160-6500 years, even at a rate of usage that is 7-8 times today's. And this still assumes the once-through fuel cycle.

The point of all this is that the total reserve amounts increase very rapidly with decreasing concentration. The Deffeyes formula states that reserves increase by a factor of 300 for every factor of ten redcution in concentration. Today's high-grade ores amount to a 50-year supply, at today's usage rate, even if we neglect future discoveries of ores of similar grade. (I am absolutely convinced that the undiscovered high-grade ores vastly exceed the currently discovered high-grade ores.) Even if we assume that all additional ores are lower-grade, we still do not have a problem. The most I ever envision nuclear providing (without breeding anyway) is ~50 years at an average usage rate of ~6 times today's. This results in a total uranium consumption of ~6 times our current estimate of known high-grade ores. Six is about 300 to the 0.3 power. According to the Deffeys formula, this corresponds to a reduction in uranium concentration of about a factor of 2, very roughly. Thus, ores with as low as ~1/2 the concentration of today's high-grade ores could provide all the uranium we need, according to these references anyway.

Even if we assume that energy use in mining is inversely proportional to the uranium concentration, this would only result in a factor of 2 in energy input. As we know (and George's study "admits") the current energy inputs are a very small fraction of generated power. Twice nothing is about nothing. We will never need to get down to the ore concentrations that the study says would be a problem.

Concerning these energy inputs in general, including the inputs for plant construction, the laws of economics apply here, and pretty much cover the situation. If the fuel cycle, and plant construction, required fossil fuels with a significant fraction of the energy that the plant will generate over its lifetime, then the plant would never be economic, period. Economics would clearly show that it is cheaper to simply burn those fossil fuels directly in a fossil plant. The cost of enriched uranium ore, to make nuclear fuel, is a tiny fraction of the cost of an equivalent amount of fossil fuel, and even this low uranium cost is mostly due to non-energy costs (i.e., labor, machinery, etc...). Thus, it is absolutely obvious that the energy inputs the fuel cycle are a tiny fraction of the energy output, on the order of 1% or less.

The same is true for plant construction. If the fossil fuel energy required to build a plant were a significant fraction of the total electric energy output by the plant, over its entire lifetime, then the cost of the plant would be a lot higher (tens of billions of dollars), even if you assumed that most of the plant capital cost was from energy costs (when in fact, energy is only a tiny fraction of the capital cost). The bottom line is that studies have been performed to look at this, and they all show that the total net CO2 output for nuclear is less than 1% that of coal. And that's all we need to say.

A brief comment on the study's "concerns" about energy usage required for the back end of the fuel cycle. How much energy would it take to simply plop the spent fuel in Yucca Mtn? Answer, almost nothing.

Two final comments. First, and once again, economics will automatically work all this out. And if we are concerned about global warming, we simply apply a tax to CO2 emissions, which would also apply to any fossil fuel use (and emissions) associated with uranium mining. If nuclear doesn't reduce CO2, it would not benefit from t

........If nuclear doesn't reduce CO2, it would not benefit from the policy. And if uranium can no longer be economically extracted, nuclear plants will not be built, period. No need to worry. Economics, and the industry, will be fully able to handle and account for this. Once again, nobody in the industry seems to be concerned.....

And finally, if this ever really does become an issue, we can just use breeders. The study's dismissal of breeders was lame. Yes, it's true that they will be somewhat more expensive (perhaps as much as 2 cents/kW-hr more, or about 6 cents/kW-hr). In an energy starved world, this will not be much of an issue. Heck, solar's still over 20 cents. The only reason why they are not used today (i.e., why they are a "failure") is that they can not quite compete with the panoply of really cheap energy options we have today. If and when the cheap options go away (including once-through nuclear), breeders will be available. They act as a barrier that will never let things get really bad (i.e., costs will never get much over 6 cents). Because breeders represent a nearly inexhaustible source, no matter how you look at it, and no matter whose numbers you use. The use of breeders completely eliminates all the arguments and issues raised in George's reference.

And there are a huge amount of factors which combine to make any particular design comparably safe to another, many more than can be reviewed here. I would refer you to a text such as Ronald Allen Knief "Theory and Technology of commercial Nuclear Power" 2nd ed. among others, but the CANDU6 is broadly acknowledged as a very safe design, e.g. triple redundant automated controlls which enormously reduce dependence on operator input.

I stated that other countries, e.g. South Korea and China, would find the CANDU6 to have an overwhelming economic advantage, a situation which is not evident. e.g. AECL has just finished building a group of CANDU6's in china (on schedule, under budget, considerably lower capital cost than your estimates), and now the Chinese are shopping for a new group of reactors. Latest word is that a US design is the frontrunner, which indicates the minimal advantage of the less intense fuel preparation.

The notion that wind power automatically creates a 26%/74% wind/simple-cycle mix that could be replaced by a 100% CCGT is total fantasy. Viewing the 74% as "missing" power that must be replaced is valid in only two cases, and both of them are imaginary: 1) All of the wind power is produced in the middle of the night, when only baseload plants are in use. 2) The demand on the grid is completely flat.

In both of the cases, a wind unit operating at 26% average capacity does indeed require matching with other units that cycle and operate at 74% average capacity factor.

In the real world, demand cycles up and down, all generating technologies have both scheduled and unplanned outages/turndowns, and there is reserve capacity.

The result is that wind power (and other forms of renewable power--Stevens promised to expose renewable energy and directed his fit only at wind) has little or no impact on the operation of baseload plants when wind capacity is a sufficiently low percentage of the overall generating portfolio. One study I very vaguely recall (Pace University, in the late 1980's I believe) put the figure at 13% for at least one renewable technology (possibly photovoltaics) or (I did say vaguely recall) or a mix of non-hydro renewables. Your mileage may vary.

I was so put off by the 74% nonsense that I didn't even bother to read Stevens long (and irrelevant to the topic of the article) defense of nuclear power. I am not a nuke hater. I have a substantial (for me) position in Exelon stock because of their record with their nuke fleet. I am a hater of dishonest rants.

I suppose that some readers will be relieved to learn that I never got around to having any children. It is finally dawning on me that a hair shirt might not be much of a babe magnet.

I will not be able to do justice to all of the comments that have been posted in response to my last remarks. Mr. Sutherland’s technical knowledge and expertise is impressive, and I will be studying his work as time allows. His speculations about my personal life and philosophy were interesting. Mr. Gould’s comments were entertaining as always. I am particularly impressed by the energy and breadth of knowledge that Mr. Hopf has shown in his latest post. He has made the most rational and earnest defense of nuclear power that I have ever seen. How he did it in one day is beyond me.

Well, I have to go now. I see somebody putting out a perfectly good bench grinder for the trash man.

- It would make sense to give wind generation some capacity credit on a regional basis if the region has several geographically diversified wind farms.This capacity credit can be predicted through stochastic analysis or determined through analysis of actual generation patterns.

- The growth of wind energy will bring some economies of scale and some technological progress, which may be substantial enough to improve the cost/benefit aspects of wind generation. In this context, the tax subsidies are not wasted. We need to spend money and to experiment if we are going to get anywhere, as we do in many other areas (e.g. space travel).

- Renewable energy is not the answer to our energy problem but it does have a place in our energy future. It can provide a cushion and a hedge for fuel rices and improve the quality of the generation mix.

George Fleming:

The study that you quote (http://www.repp.org/repp_pubs/articles/resRpt11/subsidies.pdf) states that the reference for a graph of levelized cost of nuclear power is Energy Information Administration/ An Analysis of Nuclear Power Plant Operating Costs: A 1995 Update conducted in April 1995 using the latest available data at that time. The study is quite detailed - a total of 74 pages.

The original study was conducted using a completely different measure than the one quoted by the Renewable Energy Policy Project study. Instead of determining the cost per kilowatthour of production, the study was conducted using accounting data that reported the total costs. The researchers then divided that cost by the total plant capacity to determine the annual costs per installed kilowatt capacity.

The authors of the DOE/EIA study dedicated several paragraphs to explaining that their measure could not be directly converted into cents per kilowatt hour because they did not collect sufficient information about the actual production from the plants.

Do you know how the REPP study made the conversion?

Also, it is important to note that the last data included in the study came from 1993. It is more than 10 years old and reflects a completely different set of circumstances than exist today.

It is getting more difficult to obtain cost data about nuclear power from the EIA, but the most recent information that I have been able to find from that independent statistical body is that the average O&M cost for nuclear plants is running about 1.7 cents per kilowatt-hour, about 10-20% less than the average O&M cost for coal, and several times less than the average for oil, gas, and renewables other than hydro.

The "renewables" advocates are currently arguing to substitute gas-fired gen for all the nuke and coal, because it does a better job of following the wind gen's output. They'll have everyone increasing dependence on imported fossil before they're done.

Quote "The discussion surrounding the additional costs caused by feeding wind power into the grid thus hinges on a crucial issue: The energy supply system must undergo a level of restructuring it has not experienced in the past 50 years. Large-scale block-type power stations, which only yield a return across many years of operation, will increasingly be replaced by relatively small, flexible and profitable units (the depreciation cycle of nuclear power plants is 40 years, that of wind and natural gas power stations is 20 years). Gas-fired power stations, as well as wind farms, will be performing an extensive range of tasks in future electricity generation."

Some other good renewables...

Geothermal... >90% capacity factors... There's sparce operating information to go off of (trade secrets) but it seems like there's regional potential... I think heat pumps could be grouped in with GT as well and there's definately plenty of potential with these systems...

Biomass... I don't advocate growing crops to burn but burning crop wastes seems like a good idea to me... If you do it at a coal plant it's almost cogeneration... HA... semantics... pedantics... etc.

I agree with most of Mr. Hopf's stuff but I say burn the MSW and mandate the collection of landfill gas... Maybe these projects aren't 100% renewable but they are in the same family tree...

Solar water heaters and Solar thermal in general... California is currently debating putting PV systems on a certain percentage of new homes. I think they should start with solar water heaters which are more cost effective. I wrote to the Solar Lab in Wisconsin and a Mr. Kummert replied that there was universal agreement in his lab that solar thermal systems should be pursued while PV systems continue to improve. I wrote to NREL with the PV vs. Solar Thermal question and they said they don't have an opinion. I think the real problem with renewable energy is that the National Laboratory that we have dedicated to Renewable Energy can't take a stand on whether solar thermal systems are more cost effective that PV systems. BAH...

IMO our energy policy is all goofed up. Clean coal gives me a giggle but there's nothing funny about the money we are spending on it which in my opinion will never lead to a competitive clean coal plant. The optimistic estimates of clean coal have operating costs going up 1-2 cent/kWh and you don't even want to think about the increased capital costs. We say the Kyoto Protocol is bunk but then we go and form a Carbon Sequestration Forum. I think the clean coal and Carbon Sequestration Forum are diversionary tactics by an industry on the ropes but I'm sure there's more to everything.

So... My thing is that renewables were not all created equal and but some of them deserve a place at the energy table... Nuclear is great but these excessively pro-nuke/anti-renewable articles are just as bad as the renewable happy/negative nuclear articles on the fearmonger sites.

Also... All environmentalists aren't so bad. I group things into greens (good) and deep greens (good god). I think that the greens are coming back more and more to nuclear power. Sierra Club used to be pro-nuke a long time ago and I have faith that they will come back around as the old guard in their leadership surrender to the new crop of greens that didn't grow up during the hippy midlife crisis- lets go protest with Jane Fonda at a nuke plant era. Lovelock made his big announcement not too long ago and I've heard Ehrlich has been back pedaling on his early opposition to nuclear power as well. Most of the greens I've talked to are reasonable about nuclear power and so I'm optimistic that the hole for the hatchet is growing.

Anyway...

The argument about subsidies for various sources of energy are important, but the comments so far lack breadth. The total subsidy numbers for nuclear include a long period of time (1948-1954) when it was completely ILLEGAL for anyone but the US government to get involved in any nuclear activities. There also seems to be zero recognition of all of the government DISCOURAGEMENT that has been heaped upon nuclear power developments. One key example of official discouragement for new nuclear developments is the Nuclear Regulatory Commission fee structure.

The NRC is funded with "user fees" thanks to legislation initially implemented during the Reagan years. The nuclear industry gets to pay (through the nose) for the priviledge of being tightly regulated and second guessed. Here are some example fees: New construction license application - $125,000 All other types of application - Full cost for contractors and professional staff hours for all other applications - IN ADVANCE with no limit on time spent or guarantee of success if certain criteria are met. (Note: recent applications have taken many years and cost as much as $80 MILLION in NRC fees alone) Average cost per professional staff-hour (10 CFR 170.2)- $156 (Power) $158 (materials and waste) Annual license fee per power reactor (independent of size) $3,251,000 (plus a surcharge of $183,300) Annual license fee per research reactor - $63,300 Independent spent fuel storage facility - $319,000 (plus a surcharge of $14,900) Materials licenses (complex - full table is available at http://www.nrc.gov/reading-rm/doc-collections/cfr/part170/part170-0031.html)

I might be convinced that a few nuclear subsidies exist to help out established, "struggling" companies like GE or Westinghouse, but I have a hard time believing that they are designed to encourage new nuclear power developments.

My cynical explanation for why innovators in wind, solar and biomass are encouraged while nuclear innovation is slapped with some very heavy fees is that the fossil fuel industry is not threatened by the former while its very survival is threatened by the prospect of clean, cheap, abundant, reliable, concentrated nuclear power. The real "renewable fraud" is that people have been told that they will reduce our need for fossil fuels.

The fact is that intermittent renewables cannot even supply the growth in energy demand each year and have done nothing to actually reduce the massive quantities of fossil fuels that must be consumed.

On the other hand, nuclear power, even with all of the discouragement from the government and a multitude of focused organizations dedicated to stopping its progress has replaced approximately 12 million barrels of oil per day in the world energy market using technology that was almost fully available in 1957, only 15 years after the mere existence of self sustaining fission was proven. There is a tremendous margin for future improvements and developments.

Technology that can severely disrupt such a powerful part of our economy and political infrastructure is bound to struggle; existing interests have a fiduciary obligation to protect their very livelihoods. The rest of us, however, are under no such obligation to continue to support their efforts.

It is my opinion that there is no need for nuclear power subsidies, but that there is a need to reexamine the NRC fee structure so that it does not represent such an open ended initial cost for any new system designs.

Just imagine how much innovation one would see in wind turbine design if there way a Wind Regulatory Commission that demanded $156 per bureaucrat hour to review siting, construction and designs for each windmill.

Rod Adams www.atomicinsights.com www.atomicengines.com

The bottom line is that we eventually need to create a source or balanced mix of sources that actually reduce our emissions per kWH REGARDLESS of cost. That is a given. It doesn't matter if it's Nuclear or Renewables or conservation. The problem is one of public perception of costs both dollarwise and hazard (short & long term) for nuclear power to ever take on very much more of the load. That may change after my lifetime, but I really don't care about it then. The problem with conservation is that we're not going to impliment some tax to limit or ration energy to people until we are well past emergency state. Voluntary conservation participation will always be light and temporary.

The supporting problem is that no one wants to work on the technical side of the problem. We have a lame renewable energy lab and an even lamer policy of subsidy to these fledgling industries. NREL has yet to produce anything new other than new statistics on existing ideas. Let's leave that to some department without "Lab" in it's title. A lab should do experiments that matter. The problem there is that these people work for the government and have a guaranteed paycheck and that's all that needs to be said. Funding on the outside from Federal programs is a complete waste of time to pursue. These programs regularly fund some workshop to educate people on things that everyone with an interest learns from a newsletter or two. These programs also fund the craziest ideas which have zero long term solution potential. They usually require cost sharing which puts the lone entrepreneur out of play if his development is to cost more than double what he's got left after spending his last dime trying to do it by himself before going on the funding hunt. One last problem with these problems is that they most times solicit ideas in an area that THEY believe the answer lies in. If some Da'Vinci or Newton or Tesla out there had a new twist on something that did provide some answers but he wasn't rich enough to support it's development, that idea would wither and die in today's society. I'd like to think that with all the welfare we support to all the various areas in this country, that entrepreneur would have a shot.

Enough ranting on all that. The solution hasn't been found (or at least been made public) yet, so we need to look at what we've got to work with at this point in time and make it easier for that future development to materialize. Everyone in this forum understands the fudamentals of most of the renewables and how flatlining their gen curves will make them more desireable. Storage has been mentioned a few times even, but since no response was given this was dismissed. I was disappointed to see that. I was eagerly awaiting Mr. Young's reply with a storage method. I even mentioned one earlier and was summarily disregarded. If you remember your basic physics training, you'll remember that all energy forms travel down the chain to the lowest form which is heat. Most of the energy we receive from the renewable suppliers is heat. Our suppliers being the sun, the moon, the dinosaurs and Earth's core. This is actually the easiest form of energy to store! That's amazing. Now some say that it's not the easiest to retrieve. Well, yes, you can't run a PV from heat, or a wind turbine for that matter. But the things you can run from heat don't have the cycling problem that our CCGTs have so they can be ran out of phase with the other sources like wind and PV. Personally, I don't like PV because it's been promised for too long to become efficient but I don't see that happening. Then there's inverter/expensive storage issues. However, with another renewable source running from a heat storage tank to flatten out the curve, PV now becomes more viable. Add to that wind and you've got a good mix. Add Geothermal and biomass and you're up to a full capacity generation option. Now we can't put all of those in one place and get 150 MW capacity. It just won't work. So there's the idea of distributed generation. I'm not talking about putting 10 kW capacity on every roof, but how

In regard to the storage, why isn't this model being used? I'm referring to combining multiple renewable sources into one to gain capacity. Is there any argument that says we can't provide the same supply as the demand with the excess going to storage if we combined solar thermal with wind and PV?

I wasn't trying to push any one idea or even mine. I was looking for comments on the state of how this country is addressing the problem. I have encountered so many people who have all the answers and they mostly stem from policies of regulate this or that and what industry is worth promoting. The really sad thing is how many people I've personally encountered that have hundreds of grand invested here or there but won't join a $5000 buy-in fund for some new tech renewable program that they vocally say 'we' should push. I just don't understand that mentality. My life's IRAs amount to less than 10,000 and I have nearly $2k in alternative energies.

The difficulty with combining multiple renewable sources is COST. Duplication and redundancy are not cheap and integration of multiple resources is complicated. No matter what you do, you will find that sources like wind, solar, and biomass are diffuse and difficult to gather. Pennies are money, but they cost a lot more to handle than $1000 dollar bills.

In one of your previous posts you dismissed nuclear power with the oft used excuse that public perception will halt the development. You also implied that you do not care much about the future beyond your own lifetime.

I have been around long enough to know that it is easier to change public opinion than it is to change physical laws. I am also old enough to care about what happens to the world after I leave - I care about what happens to my daughters and the children that they will have.

Nuclear fission is capable of supplyiing ALL human energy needs for many hundreds of years. It can replace hydrocarbon combustion as mankind's primary way of moving goods, controlling local environments, and forming finished products from raw materials. It is simple, clean, abundant, and pretty darn cheap if done properly. Its waste products are tiny and easily controlled.

There is no need for "balance"; this is not a journalism exercise. What is needed is an objective evaluation of available energy sources. The public will accept the energy source that provides the power that they want at the lowest cost as long as they have access to the information needed to make the evaluation.

Of course, the competition will do all in its power to keep that information from getting to the public. Even slowing the pace of sharing that information is worth a great deal of money to those that are currently supplying the world with energy resources.

(As an aside, you can get an idea of the resources that I have put into development of better atomic power systems by visiting the web sites listed below. None of our work has been funded with government money and we have no intention of asking for any. I do need some help in lowering some of the "barriers to entry" that the established energy industry have erected, however.)

Rod Adams www.atomicinsights.com; www.atomicengines.com

I knew that "beyond my lifetime" comment would come back at me. The context of that statement was (non-obviously) whether or public perception selects Renewables or nuclear power. Either one will keep the lights on for quite a while. I am a very strong proponent of viewing this in the long term. By your comments, quite possibly longer than you. My comments only stated what others think about nuclear. My personal opinion of it is that it's not renewable and will require mining, transport, highly trained maintenance and engineering crews, continual disaster drill / public awareness, and long term storage. None of those go away when the day comes that we say nuclear energy generation is fully mature. I have no problem with its use as an interrum source.

I also think that 'pretty darn cheap' is a relative term. I don't see it that way. In my humble opinion, I see the future (beginning in 50+ years) as being majority powered from plants/sites that are 100% renewable and only scarcely manned. I know of numerous engineering projects that were over engineered and have lasted nearly 100 years rather than the 10-20 yr life expectancy we shoot for today. This can be built into the plant when economies of scale bring the price down. The best way to describe this is to go hypothetical. Let's say it's 20 yrs from now. We put up a tower who's cost is 60% of today's cost because they're going up all over the place. We put a wind gen on top. Again, it's cost is .... maybe 80% of today's. Built into the the north face of the tower is a heliostat receiver for solar thermal. Its cost is negligable, again because they're commonly done with the towers. An array of marginally intelligently controlled mirrors are scattered around this tower. The gearbox and controller are so common that they can be purchased at Radio Shack for peanuts compared to what's available off the shelf today. Its controller has one setting - where's the tower - so anyone can set it up. From that position, it finds the sun and splits the difference. The glass comes in a frame based on the distance from the receiver (focal point). It's mounted on an ordinary pipe set at no particular angle or plumbness. The mirror array cost is possibly 20% of todays cost. By the way, I'm just using today's dollars for these prices. The receiver is piped through a burner to a heat tank underground. Its exit runs through a bank of Stirling engines connected to generators in any configuration you like. Now comes the only complicated parts. The controls for receiver flow/temps, burner temps/flows/feeds/ etc., Stirlings, generators, and wind gen all need to be coordinated and calibrated. I've automated enough plants to know that once you purchase the end measuring device for each measurement, your high cost (today) is only the setup and configuration. If these were commonplace, then that would simply be a program stamped on a template CD. The only safety factors are basically for equipment and working with the high temp stages, and the electricity. I think that this type of generation plant would be relatively cheap compared to today's idea of a typical plant. We have wind farms today that have many many turbines wired together. Are you saying that putting this setup in place would be more expensive ( $ / kWH ) than a bank of 4 large wind turbines? .... especially when you consider the end result capacity factor? I highly doubt it.

The last point which I briefly touched on up front is that once this is in place, the only real cost is going to be unexpected maintenance. Broken mirrors, frozen bearings, split hose, bad temp transmitter, load more biomass fuel etc. There won't be a need to have operators or maintenance crews. Automated warning calls can be made from the computer for alarms and iminent failures. There's no extra expense for that capability. I've put it in place for the total cost of a phone line and a modem. So now we have a 100% renewable system with 100% (ok, how about 99%) capacity factor and maybe .5 - 2 MW capability. I'm guessing that the cost by then will be less than a couple big wind gens today. Sure that's higher than a coal or gas plant. Let's compare the total life cycle cost on a $ per kWH basis and I'm sure you'll have to agree that even nuclear doesn't compare. What is the total install cost (all inclusive) and yearly operating cost of a nuclear plant these days anyway? Divide that out for me by a 2 MW renewable plant that costs $1M up front with $20,000 total annual operating cost for 20-60 years.

I'm just trying to be truly objective.

1) I suspect you might find the mtce costs would be a killer, though i'm sure you must have considered that.

2) Stirling engine just makes me edgy, unless you've got a very good reason to prefer it to a positive displacement Brayton engine, Brayton turbine or even organic Rankine cycle. Why Stirling?

3) Ideal solar locations are notoriously devoid of water for growing biomass. What compromise? Is it worth it?

That said, I'm pretty sure you don't mean Metric Ton of Coal Equivalent when you ask of MTCE costs, so I'm not sure what that is. I found no reference to its definition online. The only costs I can forsee would be install, maintenance, land lease, management. In my best guess scenerio, I would assume a local utility company would put up the install cost, maintain it with around a .2 FTE, contract with some land owner on the lease, and manage it's operation and control. If this doesn't answer your question, then I must plead ignorance and request more details.

Stirlings are inherantly more desireable in this project than a high pressure / high speed turbine. We're talking about a system that it's hoped to run by itself most of the time. I would not want to trust a compressor and turbine to start/stop/ramp without the level of controls being at a very expensive high quality level. A Stirling can run more on the lines of a diesel or gas burner. As I see it, a Stirling can have a better efficiency as well. It is also not as RPM or load dependent for efficiency. I have been working on Stirlings for a while now and can only say that a large portion of 'common knowledge' on them is slightly flawed. As far as a positive displacement Brayton goes, I'M edgy about that. It just seems to me that friction and other seal losses will kill it. I'll wait to see them accomplishing high efficiency at high power.

I agree that "ideal" solar location are deserts, but that's not the point of this exercise. The point was that we put multiple sources together on one site for capacity, not to maximize any one source. Most sites have a strong preference for one source and tremendously lack the support for others. That means that we'll be putting in a solar thermal system where we wouldn't have normally selected to do so. However, if we don't just look at the solar side, we see the entire system is much more capable than just a wind tower alone. Some sites will prove best with only geothermal and PV for example. In any case, we have to cover the down time of all of them with some storage. Heat is great for energy storage for short term and daily curve shaping, but I'm guessing that a crop of some uncontrolable weed or sugar cane on the land is better for seasonal storage. I don't really think that a pure desert where nothing will grow needs much support from biomass growth to match its production graph closer to electricity demand. Obviously some sources won't be as cost effective to install in certain places but the overall goal is to get a package of standard options mass produced to the point that you can call Joe's Renewables and he can come out and install a system with pepperoni and sausage and keep the cost to its competitive minimum. (sorry, I couldn't resist that one) The only requirement is that the overall minimum capacity remains above some set regional requirement. Otherwise, it's addition to the region will cause the problems mentioned in the original article way way above.

BTW mtce is just my abbrev. for maintenance.

And all those overlapping systems are going to be very expensive...

Solar thermal is going to run $3000/kw (Google...Sargent and Lundy, Hawaii assessment)... Wind $850-1000/kw ... AND remember they aren't going to line up...

And don't put so much stock in capacity factor and automation. Plants shouldn't run all the time. I remember an AREVA rep telling me he calculated peak economy CFs at 93% or so. You've got to take things down and work on them. Have you ever worked in a plant? Things break believe it or not. I'm just trying to say, don't get hung up on CF... Money in Money out is the bottom line...

My Jules Vernian dream for solar thermal is that it go directly to H2. I'm enamoured with the thermochemical hydrogen cycles. The low temperature (500-550C) Chlorine-Copper cycle can make hydrogen at just over 40% efficiency. If you generate the hydrogen directly you don't have to worry about all these complicated (although brilliant) molten salt thermal storage systems. You don't even need to use a power tower... cross-axis troughs can concentrate sunlight to 550 C... What do you do with the H2? If the plant was in Mojave you could send it to LA's refineries for heavy crude upgrading... the fertilizer market or empty petrol resevoirs for later use... The thermochemical cycles aren't quite ready for the show but they'll get there... The solar market will likely feed off all the nuclear H2 research up at Argonne... Hopefully anyway...

I think we may be on different scales of generation in our scenerios. I agree with your install estimates for larger scale plants, however in a smaller scale and after they become commonplace, I believe many numbers will change dramatically. I'm working on enhancing the output of solar thermal systems and truly believe that, not counting the tower, switchgear or mirrors, it can be installed for $300-450 per kW.... eventually. If this was integrated into a wind site's existing tower, we would only have to add in the mirrors. I'm estimating that they will end up costing under $250 per square meter installed. The insolation of the region determines what that translates into for $ / kW. If we only get 1 kW per sq. meter, then the mirrors will be another $250 per kW. There's some overhead cost like piping and storage that won't vary that much with the size of the solar side. The rest of the cost is in switchgear and controllers, some of which is already installed for the wind generator. Basically, I'm saying that I see the solar side as costing less than $1000 per kW. That makes it cheap enough to implement with the wind since most of it's cost savings are because the tower and electicity distribution equipment are being shared with wind's. I understand that this 'sounds' more complicated but KISS is one of my favorite quotes and I think this adheres. This setup is essentially upgrading a wind site to include solar for half the solar cost. I understand that troughs will work but I think the temp has to be much higher to transport large energy quantities to storage with minimal parasitic load. A mirror on a pole is much simpler and more concentrated than every collector having it's own pipe, pump and control. Then all that plumbing has to be coordinated with tracking unless you just want to not chase that extra free sun. There's a guy in Minnesota (can't find the link) who's selling 2 axis tracking controllers for $20 and it contains $2 worth of shelf parts. We certainly don't need an Allen Bradley SLC-500 or something to run these mirrors. Let them be autonimous - one break / 1 failure / 1 less kW until it's fixed. We don't need each motor or gearbox to last 50 years. They never do anyway. Get cheap ones and make sure you implement them so swaps are 5 minutes. Then buy 20% spares and save half the overall cost. Addressing your other question, Yes I've visited a plant before. Lots of summer jobs, then later I fully automated steam and waste water treatment plants. I'm talking bid to training and everything in between. Now I automate efficiency statistics for one that's in major transition. I've specified everything from transmitters to plcs and personally written all the programs for it. You can believe me when I tell you that "low bidder" and contractor overlap are half the cost of a plant. Oh, and everything that is "too complicated" to automate is exactly what should be automated and the more savings will be realized. All of this extra cost is nearly eliminated if you do a second boiler or chiller that's identical. A full plant that's just like the first is a real bonus for the integrator. Free money.

Let me toss back to you my Jules Vernian idea. Utility company shops for plant and decides on my company for example. I have prints and plans, parts and programs ready to go. A team builds the heavy construction, and is followed by another team that installs and calibrates the various systems. An App Engr follows and copies a CD and then starts the plant up for testing. There are no competing companies to argue scope, change orders or punch lists. When the plant is done, it's bought off. Period. The savings are there because they put an identical plant in last week somewhere else. All critical systems are slightly over engineered for durability and non-critical systems (like a single mirror drive) are as cheap as possible. I've seen some cheap equipment last a very long time. The only problem with that is the time & cost of replacement. If the average lifespan of the cheap items is 80% of the expensive ones and it's cost is 40% as much, then we can buy a lot of spares for the difference. Not to mention that stretches out the capital cost of that equipment and allows for better or cheaper upgrades down the road. It lowers the initial cost of the plant too, which makes financing even more available. Keep in mind that I'm talking about small plants scattered around the countryside, not one 500 mW plant. Mostly, I see the land owners doing some routine maintenance and supplies refilling per their contract, so

Back on topic... Sure, you can pick this sytem apart. There are many flaws remaining, but I never said I have the answer, just an idea that I believe has merit. The main point is to show that if we support this technology to the point of mass competition, we don't have to make our decisions of what source is most cost effective to put where. The bottom line may be the only thing companies look at, but that certainly isn't what's best for the environment. Are we supposed to gather our wind on this ridge and our sun in that desert and transmit the power opposite ways twice a day to make up the differences in the other zone? That's just silly. I would rather spend more up front to put extra capacity in each and let them balance themselves out in their own zone. That's why the heat storage setup is needed. That just happened to coincide with burning something to add heat when the system came up short. I wasn't advocating balancing the solar with biomass, just filling in the valleys that got missed due to a big storm or cold streak. Remember, these have to eventually become trusted as full capacity in the public's perception. Then again if you want to utilize all the bio you can produce, it will just add to the pie. As far as where to 'put' these plants, that will be for the local people to decide. I want to make small turnkey plants available at a cheap cost so that local utilities can weigh that agains a single source that they are considering. I think the market will take care of the rest. In most areas of the country, there are people that, at least on a small scale, are taking risks with most renewable sources. What I mean by that is even in sunny Arizona, there are people with windmills. In windy Wyoming, there are solar cells and solar thermal. In most areas of the country there are geothermal heat pumps and other sources. My town can't decide on solar or wind due to cost, resource map info, public pride in the project and location. Makes the argument of matching the resource map sort of moot, doesn't it. If they don't want to see a wind turbine then the technology doesn't come here I guess and our town will just put in another CCGT. The wind proposals have to meat to make the sale due to the CF. So now where do we go?

I really wanted to keep this short, but I wanted to also regale you with a couple automation savings stories. The plant I'm sitting in now has their most efficient boiler (120,000 lb) running on $6.18 /MMBTU NG at 10% baseload and getting 63% efficiency when it is usually over 80%. That steam is powering a 5000 ton chiller for 1200 tons of current production. That's 24% loaded. They're doing that to break it in for the 3rd time in a year due to breakages. The first one was that we had to retube the entire thing because the manual operators didn't watch the chemical feeds close enough and it scaled up. Cost over $150,000. Then they forgot to open the vent when shutting it down and the vaccuum sucked in the drum access doors so many times that we had to have it remachined. Cost over $30,000 total. Then the maintenance guy took a month to weld in a different catwalk so the operators could access the vent easier. He ended up replumbing the line to the desuperheater and killed that. Not sure about the replacement cost but expensive. The 2nd and 3rd desuperheaters didn't work because they now had different start-up techniques which the operators failed to read in the manual. So basically, we've been down for 5 months (scattered total) and ran it for 2 months solid testing at such a low load that it's very inefficient. Next to it, we have an 80,000 lb boiler that would get 76% efficiency at that same load. Next to chiller #3 (the 5000 ton steam chiller), we have a 1500 ton electric chiller that would much better fit our current load. On top of all that, we've spent over $250,000 in contracted repairs and paid at least 1 FTE for maintenance on this system. My previous plants have the chemicals automated and except for PM, they don't vary more than 2-3% calibration in a year and they don't need a catwalk on each boiler. If you're curious about more stories, feel free to E-mail me. I've got tons of them but they're sort of off topic here but I just couldn't resist.

It provides the perspective that is usually missing in too many of these energy debates.

John K. Sutherland.

Wallingford,Conn. And Bangu , Malaysia , June4,2004 – For the past six months Proton Energy Systems’ HOGEN RE (Renewable Energy) hydrogen generator has played a critical role in powering the first fully sustainable house in the world that runs entirely on hydrogen.

Malaysia’s Eco-House , an ambitious Solar-Hydrogen powered home sited at the University Kebangsaan Malaysia (UKM) in Bangi,Malaysia , utilise a photovoltaic (PV) electricity production and storage system in conjunction with Proton’s HOGEN RE hydrogen generator and a fuel cell to capture , store , and regenerate the electricity necessary to power household appliances.

Sunlight gathered by 42 PV panels located on the roof of the house is converted into electricity , which in turn feeds the HOGEN RE hydrogen generator inside the house. The HOGEN RE generator uses that electrical energy to electrolyze water , producing oxygen and hydrogen. The hydrogen then is stored in a 1500 liter vertical storage tank at 13.8 bars. When needed , the stored hydrogen is used to feed a fuel cell that powers the household appliances.

Malaysia’s Eco-House was jointly designed and developed by Professor Kamaruzzaman Sopian , director of UKM’s Advanced Engineering centre and architect Shah Jaafar to further study solar hydrogen technology as a viable source of energy for residential developments.

Proton’s HOGEN RE hydrogen generator is designed to make maximum use of intermittent renewable energy while still ensuring a reliable hydrogen supply. It may be powered through either 100 % renewable energy sources , such as solar , wind, or wave-generated electricity , or any percentage combination of renewable and grid power.

The unit continuously and automatically adjust for changing renewable power input to maximize hydrogen production. Proton’s HOGEN RE hydrogen generator has a maximum output capacity of up to 40 scf/hr or up to 1.0Nm3/hr.

“The primary benefit of the HOGEN RE hydrogen generator is that it can accommodate a constantly changing mix of available energy sources”,said Joh Speranza , renewable program engineering manager , Proton Energy Systems. ‘It’s a flexible , dependable , environmentally superior product that adapts to produce hydrogen by the most efficient method available. The HOGEN RE system will take as much energy as it needs from the grid to augment renewable energy inputs , ensuring operation 100% of the time”.

Proton Energy Systems President and CEO Walte (“Chip”) Schroeder said , “ We are excited to be part of the project at UKM , which has the potential to show people across the globe how renewable energy sources can power their lives and reduce dependence on their countries’ energy grids. It’s always been part of our business plan to apply our core competence in hydrogen generation to the advancement of sustainable energy”.

Since they were first introduced in 2001 , HOGEN RE hydrogen generators have been sold to hydrogen gas users around the world. HOGEN RE generators are currently used to supply hydrogen gas in generator cooling, materials processing , semiconductor manufacturing, fuel cell research and meteorology applications. HOGEN RE units offer a safe and cost effective alternative to hydrogen supply through cylinders or bulk gas supply. Instead of labor , fuel , delivery and storage costs associated with stored hydrogen , HOGEN RE generators make hydrogen available as needed.

Proton Energy Systems (http://www.protonenergy.com) designs , develops and manufactures Proton Exchange Membrane, or PEM , electrochemical products that it employs in hydrogen generating devices and in regenerative fuel cell systems that function as power generating and energy storage devices. Proton’s HOGEN RE and FuelGen hydrogen generators produce hydrogen from electricity and water in a clean and efficient process using its proprietary Proton Exchange Membrane (PEM) technology. http://www.fuelcellsworks.com/Supppage741.html

The math for translating electricity into hydrogen-based fuel cell transport is fairly straightforward. The theoretical efficiency of converting electricity into hydrogen via electrolysis is 39.4 kWh per Kg of hydrogen. Assuming we place a 75% efficient electrolyzer system at a typical gas station, the electricity requirement per Kg of hydrogen rises to 39.4 divided by .75, or 52.5 kWh per Kg.

Now let's put that hydrogen into a current-generation fuel cell demonstration vehicle that can travel 90 - 100 Kilometers (or 55 - 60 miles) on one Kilogram of hydrogen. Net result: a Kg of hydrogen "costs" 52.5 kWh to produce and provides better than 55 miles of driving, or just about 1 kWh of electricity to drive one mile. If the cost of electricity at the gas station is, say, 7 cents per kWh, this equates to 7 cents per mile as the fuel cost of driving a fuel cell vehicle. That cost is perfectly competitive with today's gasoline internal engine automobile. If gasoline costs $1.70 per gallon, then a 20-mile per gallon car costs 8.5 cents per mile.

Most analysts are quite surprised when they first work through the economics of hydrogen fuel from electrolysis. The presumption is that the net energy cost of making hydrogen from electricity is prohibitively high. How can the fuel value at the gas station possibly be greater than the fuel value that went into making electricity in the first place? The answer of course is that the cost of the BTUs used to make the electricity is much lower than the value of transport fuel. The variable (fuel and operations and maintenance) cost of electricity at a coal-fired generating plant is only about 1 cent per kWh (or about 15-20% of typical commercial electric prices).

Again, on a gasoline equivalent basis, the generating cost of base load electricity is perhaps one-eighth the value of the fuel that it can replace if electrolyzed and used in a fuel cell vehicle. It's as if we start with a gallon of water at the utility generator but when it gets to the gas station the water has turned into wine. Sure, we spilled some, but wine is worth enough more than water to overcome the shrinkage.

So the reality is that the variable cost of fueling a fuel cell vehicle with hydrogen from water is much more interesting than most people initially anticipate. Now take into account that electrolysis permits us to leverage existing electricity and water infrastructures. And because electrolysis technology is modular and scalable, it is clear why hydrogen from electrolysis is gaining credibility as perhaps the most logical way to achieve the introductory phase of the hydrogen fueling infrastructure.

Proton Exchange Membrane (PEM) electrolyzer technology has been used successfully for nearly three decades on submarines and in spacecraft to generate oxygen for human life support needs. Fuel cells use the same technology, converting hydrogen into electricity. To produce hydrogen instead of electricity as the end product, the fuel cell is literally run in reverse: taking in water and electricity and producing hydrogen and oxygen. PEM electrolyzers incorporate a solid polymer membrane that helps manage the electrolysis process in such a way that hydrogen ends up on one side of the membrane, while oxygen remains behind, suspended in the water that serves as the "feedstock" for the system. The result is a supply of pure hydrogen and, if needed, pure oxygen.

One might wonder where the practicality is in making a fuel cell that runs backward. After all, if the excitement surrounding fuel cells is that they can cleanly and efficiently convert hydrogen into electricity, what would be the sense in squandering that electricity by turning it back into hydrogen? From a "net energy" perspective, it would seem that it takes more BTUs of electricity than are contained in the hydrogen produced from electrolysis.

The answer begins with an acknowledgement that the amount of energy consumed in PEM electrolysis is indeed greater than the amount of energy in the resulting hydrogen. But this trade-off can make good economic sense in a variety of circumstances. For example, if the electricity used to make electrolytic hydrogen comes from low-priced coal or nuclear power sources, and if the hydrogen is then use

This is the core problem with every one of your posts. Dont worry, businessmen aren't ignoring these systems just to upset you, there are usually very good reasons. What's needed is research to eliminate the platinum problem. One professor out in Minesota has patented an alternative which looks promising but definitely hurts your conversion calculations somewhat.
