Scientists Invent Cheap Hydrogen Production Method

Engineers from Purdue University have developed a technique for producing hydrogen at a cost that would be competitive with other energy technologies.

The researchers used a new aluminum alloy to produce hydrogen by splitting water. The alloy contains 95 percent aluminum and 5 percent of a combination of gallium, indium and tin. The key is its reduced use of gallium, which is very expensive, allowing hydrogen to be produced less expensively
“We now have an economically viable process for producing hydrogen on-demand for vehicles, electrical generating stations and other applications,” said Jerry Woodall, professor of electrical and computer engineering at Purdue, who invented the process.

Also, the alloy can be recycled several times, further reducing the cost and lowering carbon dioxide emissions to about one-third of that produced in a gasoline engine.
