Nucular Hydrogen Economy
Mark Baard writes "The hydrogen economy will at least in part be based on nukes. The DOE will build a pilot high-temperature, gas-cooled reactor (HTGR), which theoretically can co-generate electricity and hydrogen, side by side, inside a cheap modular unit."

Here is the text of the article...
On a sunny Saturday morning 30 years from now, you may decide to take your family for a ride to the country. You'll still be driving a car, and you may still get stuck in traffic. But that's OK, because the only thing you'll be breathing in is water vapor from the car in front of you.
Welcome to the seemingly benign "hydrogen economy" President Bush has touted over the past year. Pollution-free cars. Abundant fuel. A cleaner environment.
But there's one factor the president isn't talking much about: the hundreds, perhaps thousands, of new nuclear power plants his administration imagines making all of that hydrogen.
The Bush administration and Senate Republicans want to give billions of taxpayer dollars to the nuclear industry to make high-temperature, gas-cooled reactors (HTGRs), which--theoretically--can co-generate electricity and hydrogen, side by side, inside cheap modular reactors. Advocates of the plants say they wouldn't need the expensive protections required for traditional models.
This summer, the Senate is expected to vote on the Energy Policy Act of 2003, which includes funding for new HTGR plants and the construction of a pilot co-generation facility to be run by the U.S. Department of Energy in Idaho. The bill was sent to the full chamber by the Senate Energy and Natural Resources Committee last month.
Spokespeople for the committee and the DOE say the aim is to cut greenhouse emissions, since energy companies continue to use coal and natural gas in making hydrogen. But small, modular HTGR plants may do it more efficiently and cleanly, they said.
That all depends, of course, on how you define "cleanly." To extract hydrogen from water--to get the H out of the H2O--you first have to make steam. The modular nuclear plants would do that without polluting the air, but would also leave behind radioactive waste.
Scientists have not yet designed a nuclear facility whose safety and efficiency trumps that of gas or coal. One proposal, from MIT, has a nuclear reactor sitting under the same roof as a chemical plant bubbling with sulfuric acid and hydrogen iodide.
Each modular plant would produce as little as one-tenth of the energy of a single light-water reactor. And since by some estimates the United States would need the equivalent of 500 light-water reactors to produce enough hydrogen, it may take thousands of modular plants to get the same job done.
The nuke industry, not surprisingly, says it's interested in joining the hydrogen economy. Entergy, the second-largest nuclear energy producer in the U.S., hopes to break ground on its co-generation Freedom Reactor within five years.
But only the feds seem willing to pay for the research and development that would make the futuristic plants a reality. "We generate electricity," said a spokesperson for Exelon, the country's largest producer. "We're not heavily involved in funding research and development."
Taxpayers may soon be. The Senate's energy bill affords the DOE $1.1 billion to build an HTGR co-generation nuclear plant at its Idaho National Engineering and Environmental Laboratory within 10 years.
The bill also proposes to kick-start a nuke renaissance by subsidizing half the cost of six to 10 new HTGR power plants in the United States.
"We need to move toward clean-air energy sources that are more reliable than wind and solar," said Marnie Funk, a spokesperson for New Mexico Republican senator Pete Domenici, chair of the energy and resources committee.
Renewable energy sources, like wind and solar, are emissions-free. But the sun doesn't always shine and the wind doesn't always blow. Many people also see wind turbines as an eyesore: Cape Codders are fighting plans for an offshore wind farm that would obstruct their views. "And then you've got the bird issue," said Funk. Wind turbines earned some notoriety by killing as many as 50 golden eagles along California's Altamont Pass during the 1990s.

This is really a revival of a program that Clinton zeroed out the funding for in 1992. Supposedly, (I had friends working on it) Al detested the thought of anything nuclear.
So long and thanks for all the fish . . . !!!
I'm aware of two economic methods of generating H2. The least economic is from cracking water using electricity (the topic of this article). The most economic is by cracking natural gas - this is the method used by everybody I know of in the chemical industry.
Natural gas, mostly methane (CH3) is reacted with steam (H2O) such that CH3 + 2H2O = CO2 + 3.5H2
So, when somebody says he wants a hydrogen powered vehicle, what he really means is he wants a natural gas powered vehicle.

OK, we can cut it out with this "Freedom" stuff everywhere now. Tell Entergy that they can go back to calling it their "French" Reactor again, the war is over.
It should be noted that many of these technologies are theoretical and are the result of basic research combined with applied research. While I am not a fan of the current administration, I do tend to agree with their view of nuclear power as long as newer safe designs are implemented. To those who are critical of this, it should be noted that we have a large coal burning electricity plant in central Utah that produces as much radioactivity and throws it into the atmosphere as Three Mile Island did. This is because of the high uranium content of the coal. At any rate, the basic research is important here and should be funded along with the applied research into such things as computational modeling of high temperature physics.

The amount of anti-nuclear sentiment in the U.S. today is just silly. If you think nuclear power is unsafe or damaging to the environment, well, it's possible to make that case, but it's a battle that from both the public safety and environmentalism standpoints is FAR, FAR less important than a bajillion other battles that are just being neglected because they don't have a dramatic scare word like "NUCLEAR!" attatched to them. Moreover, the end result of anti-nuclear protest is NOT going to be in any way to encourage inefficient "alternative energy sources"; the only result will be that corporate interests will stay with "safe" (becuase it doesn't cause protestors) fossil fuel based energy sources, thus increasing our nation's depednence on oil just that little bit further, spewing god knows what horrible things into the air day and night, and harming the environment more than nuclear power ever could. Way to go.
If nuclear power can have the added side effect of producing Hydrogen to use in hydrogen power, then great, that's just one more advantage. Now if only we could convince the U.S. to use breeder reactors so that there wouldn't be quite so much of that pesky nuclear waste that the protestors keep going so much on about.
Note to the anti-nuclear protesters and PETA: You are not doing anything productive, you are reflecting badly on "the left", and you are pre-empting actual important work being done by others because when faced with a PETA or anti-nuclear story the news will run it, because those are issues that catch the public's eye, but when faced with a story in which people are protesting real, harmful corporate abuses they don't run it, because hey, they did the "protester" thing with the PETA story yesterday. Please go away.
(Although i will recognize the people complaining about the nuclear waste dump site near Las Vegas have a point-- building a nuclear waste containment policy in a *mountain* on a *fault line*, even a small fault line, is just a fucking dumb idea.)
And the methane is cheap and easy to get as well... 99 cent menu at lunch means that you can drive home in the evening...

Amen to that.
I would prefer fusion, but that hasn't been done yet. Next on my list would be space based solar power, but sadly that might take longer to be ready than fusion. The only answer that is right-here-right-now is nuclear fission. Done properly it will not only reduce carbon emissions it will even reduce the amount of radiation released into the environment (it seems counterintuitive, but a typical coal power plant will release more radioisotopes into the environment than a typical nuke plant on a per Megawatt of power produced basis).
People just have to get over their knee-jerk prejudices. Unfortunately it may be easier to solve the engineering & infrastructure problems with fusion or space solar power than it would be to get the newsmedia to engage in a sane discussion about the risks and benefits of nuclear fission. Too many of them got everything they know about nuclear power from watching China Syndrome.

One of the main benefits of a hydrogen economy is that you can generate hydrogen cleanly and efficiently in places where there is a lot of sunshine (and access to water) and ship the hydrogen safely to places that need it. Just like oil, only safer, more environmentally friendly, and renewable. And the US has lots of regions that are good for that kind of solar generation of hydrogen.

I'd prefer greenhouse gases to nuclear waste. Greenhouse gases may end up causing lots of devastation, but they probably go away within a matter of centuries. Nuclear waste poses a lethal risk for tens of thousands of years and can be used for creating dirty bombs and other mischief.
I get the feeling that Bush administration policies can largely explained as using popular issues ("the environment", "national security", etc.) as an excuse to transfer large amounts of government subsidies to big donors.
At the moment, hydrogen is very hard to extract from sea water. Basically you need to put in all the energy (more in fact) that you want to get out. The problem is that hydrogen is a great storage form for energy (like oil, batteries, gas, nuclear materials, flywheels) but not a source of energy (like sunshine, wind, waves...). We can use nuclear materials and oil as if they were a source of energy because we have access to vast amounts of them, but they are not really sources, and will run out.
Until we get either some revolutionary new method of extracting the hydrogen (wasn't there a story here about some method involving a laser heating up a large tank of water on an artificial island and breaking up the water molecules?), or we get access to the atmospheres of planets like Jupiter which have many earth masses' worth of hydrogen, hydrogen remains a storage form, unusable as a source.

If anyone can find a copy of it online, there's an excellent article from the Dec 8, 1978 issue of Science that provides some perspective. Someone cranked the numbers for the concentration of uranium in coal and America's yearly consumption, and (if I remember it correctly) they found that the trace levels of uranium were actually high enough that we'd have gotten more energy from using it in a fission reactor than from burning the coal. That means that it'd be far more than the amount of uranium consumed in reactors each year, and it's all just going straight into the atmosphere.
We keep the article posted in our undergraduate physics lab, just in case people start complaining about the weak little sources we use for radioactivity-based experiments.

And if you use solar power to electrolyse water, you have a solar powered car. The point is to create an infrastructure where you're not dependent on the type of energy - it makes no difference for your hydrogen powered car if the hydrogen was created by using coal, nuclear, solar or wind power, cow methane, or your mom pedaling on a stationary bike. You can always use the cleanest or cheapest or most readily available (depending on what your priorities are) way to create your hydrogen. With current cars, you're limited to crude oil, from which gasoline is created.

Defending my brother and the good folks at the Voice: the spelling was a joke, a reference to the fact that this potential nuclear revival would result from a Bush administration initiative. I'm astonished so many smart people in this group didn't get an obvious joke, mocking the administration.

On the contrary, the 3 cents/kwh figure for wind includes real estate costs. The 12 cents/kwh for nuclear does not include the external waste disposal costs.
The 14,000 acre area is enough wind power for the enitre United States of America using today's most modern 2.5 megawatt turbines with syncronized directionality. The land below can usually be used for farming or grazing.
The surplus and battery banks necessary are insignificant. Although the wind stops and starts, it is usually blowing somewhere on the grid. Existing grid generators will probably be phased out over time as they are replaced with surplus turbines and PEM-electrolysis fuel cell hydrogen storage tanks.
France derives 75% of its electricity from nuclear energy. This is due to a long-standing policy based on energy security.
France is the world's largest net exporter of electricity, and gains some EUR 2.6 billion per year from this.
Wastes: The national policy is to reprocess spent fuel so as to recover uranium and plutonium for re-use and to reduce the volume of high-level wastes for disposal. Waste disposal is being pursued under France's 1991 Waste Management Act which sets the direction of research which is mainly undertaken at the Bure underground rock laboratory in eastern France, situated in clays. Another laboratory is researching granites.
