"Instant" (3 min) Hydrgoen from water and aluminum alloy

Details here.

It is possible for hydrogen to be a byproduct of a reaction between water and regular aluminum, but only at extremely high temperatures or with added catalysts. Additionally, it would take hours for the hydrogen to be produced and had an efficiency of only about 50 percent.

That's not the case with this new reaction; "Ours does it to nearly 100 per cent efficiency in less than 3 minutes," team leader Scott Grendahl told New Scientist. That's a pretty impressive statistic, especially when you consider it's an automatic reaction. Aluminum and water can be transported easily and are stable. This can easily be turned into a situation where a lot of hydrogen can be produced on demand, in a short amount of time. This eliminates many of the issues that forced companies to seek alternatives to hydrogen for a clean energy source.

That doesn't mean this is the solution to all our hydrogen problems, though. There are still many questions that need to be answered.

The article then goes into detail about those questions, but at least it's a start

The first question that pops into mind is the cost of producing the aluminum. Iirc, it takes lots of energy to get aluminum out of ore. But it could presumably be recycled in this system.
