Technology Review: Cheap Hydrogen
This report is about promising new technology to make hydrogen from water via the sun. (The only current method of using solar power to generate electricity to electrolyse water is inefficient, the article says.)
This new method works directly on the water, and holds the promise of making hydrogen at the same cost as stripping it out of natural gas, which I think is the currently the cheapest option.
As the article notes, the big advantage of this technology could also be as a energy storage method for solar power stations. I assume this would be by using part of the plant to make electricity directly, and another part to make hydrogen to store for later burning if the sun goes behind clouds for days at a time.

It's a good point.
No point having solar electricity and nothing else if we don't have the power to keep things going.
And for anyone who reads and doubts me, think hospitals and life support. They have powered generators for a reason.
