Hydrogen fuel cells begin to show off in the world of competitive racing

10. Well, you've made my point.

Hydrogen isn't a source because there's no natural source of molecular hydrogen on Earth. All must be generated by electrochemical or chemical sources, all of which require more energy than is generated by the resulting hydrogen.

Hydrogen may be the best energy storage medium, however. We can use power generated by other sources -- solar, wind, tidal, geothermic, even nuclear and (horrors) oil and coal -- to split water into hydrogen and oxygen. We can store the hydrogen. (It's difficult, but we're already doing it. A lot of new infrastructure would be required to scale things up. But that isn't beyond our technology.)

My posts here are intended to educate people here on how important hydrogen can be, but also that it is not a panacea for our energy future because it is a simple fact that hydrogen is not a source of energy because Earth has no source of molecular hydrogen. NONE.
