Fuel cell electric vehicles generate their power from hydrogen and oxygen, and emit only water.
BBC: Nissan FCEV on display at a car show in Brussels in January
What emerged was a wish list from customers that included cleaner ways to burn coal and more efficient wastewater treatment systems, as well as nuclear power and hydrogen fuel cells.
In the 1950s, Russian and American scientists knew there was no limit to the power of thermonuclear hydrogen bombs.
FORBES: It Was On A Night Like This In Russia, 50 Years Ago...
And many electric utilities have facilities that create hydrogen power, but consumers can't just pull in with a fuel-cell vehicle and say, "Fill 'er up!"
And yet you can find him all over a recent prospectus filed with the SEC for Hydrogen Power, a Seattle company with a volatile stock on the o-t-c bulletin board.
It is these types of massive political and social upheavals, more than the eventual greening of global energy production, that will ensure that hydrogen power would indeed change the world.
Capitalizing on the popular mania for sustainable energy, the penny-stock operators are converting failed Canadian mining outfits and Internet firms into green machines with names like Western Wind Energy and Hydrogen Power International.
Heartening news rang forth from the renewable energy sector this week as a UN-backed study reported that the building of new renewable energy plants has officially overtaken fossil fuel plants in Europe and the US. We also took a look at two brand new types of power plants -- the world's first hydrogen-driven power plant in Italy and the first hybrid coal-solar power plant in Colorado.
ENGADGET: Inhabitat's Week in Green: of mirror cubes and urban icebergs
In terms of producing hydrogen to power a car, the unit can make enough gas overnight to provide fuel for 25 miles.
In a hydrogen fuel cell car, hydrogen gets drawn through a catalytic membrane: an electron gets stripped from the hydrogen to power the car.
The energy storage system will produce hydrogen using excess power generated from renewable energy, primarily wind power.
The problem was that the hydrogen needed to power these buses had to be brought in from Quebec.
But there is another way to power an electric car - hydrogen.
FutureGen would be a near zero-emissions plant that converted coal into hydrogen, to power electric turbines, and carbon dioxide, to be pumped underground.
Earlier this month, researchers at a federal laboratory in Colorado announced they developed a one-step process that uses solar power to convert water into hydrogen.
Some even dream of using natural gas to make hydrogen which would power fuel-cell cars, though advocates admit that these are still a long way off.
ECONOMIST: What bigger estimates of America��s reserves could mean
Wrightbus is working with the ISE Corporation of California to deliver the new buses in which hydrogen is used to power an electric drive system.
In the future, there might be a more complete solution: Cars that run on new fuels that don't emit greenhouse gases at all, such as hydrogen made with nuclear power, or cars that run on electricity that was generated with wind or solar power.
The basic idea, as is done here, of using sunlight through solar PV to electrolyse water, store the hydrogen then, when the power is required, reverse the process.
Battery power is one alternative, but so are hydrogen fuel cells, which offer greater range.
Though it appears to all intents and purposes like a state-of-the-art power station, FutureGen is actually a huge hydrogen production facility in disguise.
From the beginning, the cloud hanging over the whole hydrogen enterprise has not been the power source as such, but the intractable difficulty of distributing and storing the stuff.
And also hydrogen fuel cell vehicles where the hydrogen is produced by wind and solar power and also hydroelectric geothermal power.
In the longer run, by 2020 or so, Taniguchi envisions that there will be sufficient hydro and wind power to supply 500, 000 mainland cars with hydrogen.
These are big batteries that run cleanly for as long as hydrogen is supplied, and which might power anything in or around your home notably, your car.
As everyone who keeps up with technology knows, almost every week new developments are being made in hydrogen technology, and sun and wind power are improving almost as rapidly.
Since different sorts of living tissue contain different amounts of hydrogen, the application of sufficient computing power to the signal can turn it into a clear image of the body's interior.
Meanwhile, research into fusion power (in which energy is generated by fusing hydrogen atoms together at very high temperatures) has left behind a different kind of debris: a trail of experimental reactors, none of which has yet reached the break-even point where the amount of energy that comes out exceeds the amount put in.
The idea is to plug in electric and hydrogen fuel cell vehicles to the buildings to power up our vehicles.
