Hydrogen on demand
New fuel for 21st century -- aluminum pellets?By Julie Steenhuysen Fri May 18, 2:40 PM ET
CHICAGO (Reuters) - Pellets made out of aluminum and gallium can produce pure hydrogen when water is poured on them, offering a possible alternative to gasoline-powered engines, U.S. scientists say.
[...]
The metal compound pellets may offer a way, said Jerry Woodall, an engineering professor at Purdue University in Indiana who invented the system.
"The hydrogen is generated on demand, so you only produce as much as you need when you need it," Woodall said in a statement. He said the hydrogen would not have to be stored or transported, taking care of two stumbling blocks to generating hydrogen.
For now, the Purdue scientists think the system could be used for smaller engines like lawn mowers and chain saws. But they think it would work for cars and trucks as well, either as a replacement for gasoline or as a means of powering hydrogen fuel cells.
