A solar cell has been developed that produces hydrogen directly. Although the current process is not that efficient, it is efficient enough, and the cost of doing it is low.


"Researchers in Switzerland have demonstrated more-efficient water-splitting solar cells based on a cheap, abundant, and long-lasting material: rust. The advance could lead to a cheap and energy-efficient way to generate hydrogen for fuel-cell vehicles using solar energy."..more there

Interesting work, but I know an even more abundant source for hydrogen: sea water.

Also, I thought the problem with hydrogen power was high-density safe storage and transport. Am I in error?

No errors. Hydrogen transport and storage and the only remaining impediments to hydrogen fuel. We can make hydrogen 14,000 different ways. Most are expensive and energy intensive, but the ones that don't use fossil energy are cheap enough [compared to complacency] at this stage in the game if measured using any legitimate total accounting economics.

Well, hopefully with this system we can cut down on some of the transport required to get the hydrogen where we need it. Storage, naturally, remains a problem.
