A different method from a different university.....
A Purdue University engineer has developed a method that uses an aluminum alloy to extract hydrogen from water for running fuel cells or internal combustion engines, and the technique could be used to replace gasoline.
The method makes it unnecessary to store or transport hydrogen - two major challenges in creating a hydrogen economy, said Jerry Woodall, a distinguished professor of electrical and computer engineering at Purdue who invented the process.
"The hydrogen is generated on demand, so you only produce as much as you need when you need it," said Woodall, who presented research findings detailing how the system works during a recent energy symposium at Purdue.
The technology could be used to drive small internal combustion engines in various applications, including portable emergency generators, lawn mowers and chain saws. The process could, in theory, also be used to replace gasoline for cars and trucks, he said.
Hydrogen is generated spontaneously when water is added to pellets of the alloy, which is made of aluminum and a metal called gallium. The researchers have shown how hydrogen is produced when water is added to a small tank containing the pellets. Hydrogen produced in such a system could be fed directly to an engine, such as those on lawn mowers.
"When water is added to the pellets, the aluminum in the solid alloy reacts because it has a strong attraction to the oxygen in the water," Woodall said.
This reaction splits the oxygen and hydrogen contained in water, releasing hydrogen in the process.
New process generates hydrogen from aluminum alloy to run engines, fuel cells
Scientists have determined that an inexpensive semiconductor material can be "tweaked" to generate hydrogen from water using sunlight, a revelation that may have the potential to bolster the renewable energy sector.
The research, published in the Physical Review Journal, was funded by the U.S. Department of Energy and led by scientists at the UK Center for Computational Sciences and the University of Louisville Conn Center for Renewable Energy Research.
The team demonstrated that an alloy formed by a two percent substitution of antimony in gallium nitride has electrical properties that enable solar light energy to split water molecules into hydrogen and oxygen through a process known as photoelectrochemical water splitting. The researchers found that when the alloy is submerged in water and exposed to sunlight, the chemical bond between the hydrogen and oxygen molecules break, allowing the hydrogen to be collected to separately.

Cool, how's about we divert the 50 odd billion Obama has earmarked for that fuckin' high speed rail bullshit that will lose money to this project? Great news though, but no mention of what the time horizon is. I'm assuming a number of years.
Nothing wrong with high speed rail. It's a good idea.
How about we take the TWO TRILLION DOLLARS we wasted in Iraq and Afghanistan and use that for alternative energy.
More science than Republicans can possibly handle.

the ERORI for ethanol is negative and solar is less than 1 once you ditch the subsidies and governmental finagling to fudge the numbers.If the EROEI is 10x then it can be possible to use it to replace oil. If not, it will only be second best. I'd be very happy to see that it worked, but ONLY if it is "bigger, better, faster, cheaper", and fuck greener.
We are currently using oil from Canada's Tar Sands that only produce an EROEI of 3.5X
That is about the same as Ethanol. If this Solar Hydrogen thing can beat that & not cost more it may make it in the marketplace.
Do we get to hear about the unintended consequences before they happen ? Science tends to tell us the bad news way too late.

Don't blame science. Sometimes people refuse to hear the bad news until it's too late, e.g.AGW.

How apropos that you use that example. You're right. The science did warn too many of us too late that AGW is a total fraud. We've wasted trillions on a non-crisis that doesn't really exist anyway and we couldn't control it even if it did.Do we get to hear about the unintended consequences before they happen ? Science tends to tell us the bad news way too late.

Which ethanol are you referring to? Corn? Sugar cane?the ERORI for ethanol is negative and solar is less than 1 once you ditch the subsidies and governmental finagling to fudge the numbers.
Tar sands may not be as good as light sweet crude which is about 10 to 1, and outside of nuclear or hydro electric which are the only two better than oil. And with the technological improvements, it just gets better and better.

But nothing is as expensive as handwaivium or dumbassium when you use it as the basis of an energy policy like our current pinwheels mirrors and moonshine crowd seem to believe. I am very much worried this is another perpetual motion philosopher's stone cold fusion snake oil generator... but I hope it is true.Those substances that end in ium's tend to be rare and expensive.
