Sunlight, zinc oxide, and water goes in, hydrogen comes out. This is a prototype about to undergo 6 weeks of testing to answer the very question you pose about it being economically competitive. The main advantage this has? No emissions such as carbon dioxide.

Do any solar-powered generators of hydrogen produce carbon dioxide? Is the idea here that this would be a primary source of hydrogen for cars? Or is it only competitive in certain restricted applications?

"The main advantage this has? No emissions such as carbon dioxide."

Thats great, but who is going to use it if it isn't cheaper than alternatives?
