Re: But there is a catch. Hydrogen generally doesn't occur in nature by itself, but rather in combination with other elements. Today it is usually produced from fossil fuel.

Not even wrong.

Electrolysis is an environmentally disasterous method of producing hydrogen because of the staggering loss of exergy.

Thermodynamic fundamentals ABSOLUTELY GUARANTEE that electrolysis will NEVER be a significant source of hydrogen for bulk energy apps.

Elecytrolysis is pretty much the same as 1:1 exchanging US dollars for Mexican pesos.

There ALWAYS will be more intelligent things to do with electricity than instantly and irreversibly destroying most of its value.

See http://www.tinaja.com/glib/energfun.pdf for a detailed analysis.
