An Exciting Breakthrough For The Hydrogen Economy

advertisement

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.

Hydrogen is seen as the ultimate in clean fuels, especially for powering cars, because it emits only water when burned. U.S. President George W. Bush has proclaimed hydrogen to be the fuel of the future, but researchers have not yet found the most efficient way to produce and store hydrogen.

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.

Who's leading the conversation?
This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

Depends on how much hydrogen is in a pound of aluminum but this could be big.

    i read this on another site. It is an interesting concept. I plan to watch developments in this area and see how practical and affordable it becomes.

      It is interesting A-1. Bauxite, the component of Aluminum is one of the most common minerals on earth but Aluminum requires lots of electricity to produce.

      So you could have Windpower, producing electricity to make aluminium, which could produce hydrogen, which then could be utilized in fuel cells to make electricity to power cars. Maybe.
