DEARBORN, Mich. (AP) Energy Secretary Spencer Abraham released a ``roadmap'' Tuesday for putting fuel cells in the nation's cars and trucks, further committing the United States to a hydrogen-based transportation system.
``Creating the hydrogen fuel cell vehicle of the future presents complex technical challenges,'' he told business leaders at the Global Forum on Personal Transportation in the hometown of Ford Motor Co. ``Overcoming them will take an intensive and equally complex effort but it will be worth it because the stakes really are so high.''
The Department of Energy and the nation's leading car and oil companies began work one year ago on a ``National Hydrogen Energy Roadmap,'' Abraham said.
Abraham was holding a closed-door meeting later Tuesday with the heads of the chief executives of some of the nation's leading businesses, including Ford, General Motors Corp. and Exxon Mobil Corp., as well as the leaders of American, Northwest and Southwest airlines.
Fuel cells use a chemical reaction between hydrogen and oxygen to produce electricity. When pure hydrogen is used, the only tailpipe emission is water vapor.
The technology could have two big benefits: sharply cutting America's dependence on oil imports from an unstable Middle East and reducing the production of greenhouse gases widely blamed for global warming.
But fuel-cell technology is not expected to be widely available until the end of the decade at least.
Critics say the Bush administration and auto industry are using fuel cell research as a way to fend off calls for vehicles that get more miles per gallon.
``The whole business about fuel cell vehicles is just political theater,'' said analyst David Healy of Burnham Securities.
He said a much better way to reduce oil consumption is through gas-electric vehicles, some of which already are on the road.
``They're light years away from a commercial (fuel cell) vehicle,'' Healy said.
Abraham acknowledged that many hurdles remain.
One of the biggest challenges is finding a safe way to store hydrogen fuel in vehicles. Others are developing a hydrogen delivery network like the one that distributes gasoline to stations nationwide, and finding economical ways to produce hydrogen.
The initiative also is looking at other uses for hydrogen.
``The roadmap outlines the research, development, demonstration, codes and standards, and education efforts necessary to lead the nation to a clean and sustainable energy future,'' the Energy Department said.
Abraham said it is vital for America to abandon its reliance on oil and other fossil fuels.
``Whether it is fusion, a hydrogen economy, or ideas that we have not yet explored, I believe we need to leapfrog the status quo and prepare for a future that under any scenario requires a revolution in how we produce, deliver and use energy,'' he said.
In January, the Bush administration abandoned a Clinton-era effort to produce highly fuel-efficient gasoline-powered vehicles. In its place, the administration announced a joint effort with automakers to promote hydrogen fuel cell powered cars and trucks,
In May, General Motors displayed a pickup truck that it said was the world's first drivable fuel cell vehicle that extracts hydrogen from gasoline to produce electricity.
Hydrogen is NOT a fuel.
It will ALWAYS require more energy from another source to produce than what can be obtained by burning it.
(Unless, of course, fusion nuclear reactors ever become a reality)

High-speed rail as an alternative mode of transportation in the U.S. is long overdue. We are reaching the point of diminishing returns as we expand our 4-lane interstates to 6, 8 or (gasp!!!) 10 lanes. And even costly airport expansions make little sense when (prior to 9/11) the air corridors themselves are over-congested.
High-speed rail and maglev offer the perfect alternative to augment & supplement our highway and air transportation infrastructure. For regional trips between 100 and 550 miles, it is faster than automobile and not that much slower than air. Yet offers the potential to alleviate both congested highways and air corridors!
In light of current economic conditions, construction of this vital transportation infrastructure should be accelerated.
Well, I suppose you could choose to pour boatloads of concentrated acid on some kind of metal... but that has quite a few drawbacks to it.
So won't we have to burn a whole heck of a lot more oil to generate the hydrogen to then power the cars?
Correcto-mundo...
Or coal, nuclear, hydro dams, windmills...
However you want to generate electricity, we'd have to build a helluva lot more of.
So, like, what will we have gained?
Not a blasted thing. Only additional inefficiency and energy loss by converting energy to yet another storage medium - hydrogen. Then additional losses when hydrogen is burned and converted back to mechanical energy. (Not to mention the losses due to leakage when hydrogen is in gaseous form. That blasted tiny little molecule can leak through just about anything like a sieve. It just scoots right between the other molecules like they're not even there, doesn't even need a 'crack".)
If you're going to generate electricity, you might as well use it to directly power mass-transportation systems. Much less loss than going through the inefficient gyrations of converting to hydrogen, then back again.
Guess again, Ace.
I only advocate light-rail, high-speed rail and Maglev for those densely populated corridors and urban areas where ridership would make their use sensible.
This, of course, would enhance petroleum availability in more sparsely populated regions of the country.
And before we even consider such a marginal source of vehicle propulsion like hydrogen, we haven't even begun to discuss gassification of our vast reserves of coal, shale-oil, tar sands, etc. etc. etc.
The Federal Railway Administration has a pretty decent map showing where the initial corridors for Maglev and high-speed rail would be:
High-speed ground transportation (HSGT)-- a family of technologies ranging from upgraded existing railroads to magnetically levitated vehicles-- is a passenger transportation option that can best link cities lying about 100-500 miles apart. Common in Europe ( The European Railway Server) and Japan (Japan Railways),HSGT in the United States already exists in the Northeast Corridor (Amtrak) between New York and Washington, D.C. and will soon serve travelers between New York and Boston.
HSGT is self-guided intercity passenger ground transportation that is time competitive with air and/or auto on a door-to-door basis for trips in the approximate range of 100 to 500 miles. This is market-based, not a speed based definition. It recognizes that the opportunities and requirements for HSGT differ markedly among different pairs of cities. High-speed ground transportation (HSGT) is a family of technologies ranging from upgraded steel-wheel-on-rail railroads to magnetically levitated vehicles.The Federal Railroad Administration has designated a variety of high density transportation corridors within our nation for development of HSGT:

This is similar to the "recycling craze". Reality: RECYCLE = POLLUTION.
I gotta laugh when I see that gigantic recycling truck go down my street spewing out fumes with a big hairy arm sticking out the window dropping a McDonald's Big Mac wrapper to the ground (and that's just the first phase of pollution...)
As a matter of fact, there are.
Transrapid International is one.
American Maglev Inc. is another.
I can't help it if you insist on a naively simplistic perspective as to how the transportation infrastructure market in our nation works.
