Woodall says the method makes it unnecessary to store or transport hydrogen — two major challenges in creating a hydrogen economy.More info at MSNBC.
"The hydrogen is generated on demand, so you only produce as much as you need when you need it," he said in a statement released by Purdue this week.
So instead of having to fill up at a station, hydrogen would be made inside vehicles in tanks about the same size as today's gasoline tanks. An internal reaction in those tanks would create hydrogen from water and 350 pounds worth of special pellets.
"No extra room would be needed," Woodall said, "and the added weight would be the equivalent of an extra passenger, albeit a pretty large extra passenger."
The hydrogen would then power an internal combustion engine or a fuel cell stack.
"It's a simple matter to convert ordinary internal combustion engines to run on hydrogen," Woodall said. "All you have to do is replace the gasoline fuel injector with a hydrogen injector."

Professor Jerry Woodall and students from Purdue University claim they've found a way to extract hydrogen from water by using an aluminum alloy.
