Maybe hydrogen powered cars are back in the picture.

@sonhouse saidCorrect me if I'm wrong, but isn't it tricky to store hydrogen in a car, requiring either super low temperature, or super high pressure?

@sonhouse saidWow! They found about a hundred ways to store H. I hope they narrow it down to 1 or 2 best ways, and then we can have a serious competition between batteries and hydrogen fuel cells.

They have gone way past the need for cryogenic or high pressure storage. Metal hydrides are only one way among many other ideas in this area.
@sonhouse saidEven newer work showing new cheap catalyst to split H2 and O2 from water, using iron and nickle as catalyst instead of platinum and iridium and the like. Thousands of times cheaper to make those new catalysts.
@bunnyknight
Some folks hate the idea of using H2 but at least it gets us off the tit of fossil fuels. H2 now can be made efficiently using solar energy so it would be a variation of solar power.
