Certain areas pose the best solution to Hydrogen production. Iceland in particular. They are gearing up hard to become the first, biggest players. All that lovely geothermal energy, virtually laying around on the ground, waiting to be picked up. Gobs of fat, juicy, electric...FREE...after setup cost, and minus maintenance expenses. The big electric needs are the tickler in cheap hydrogen production. Ya know, in an alternate universe, where the world isn't all that much different....the humans there do it all with little reactors(of course, they'd never developed any religion there, so no zealot has ever thought of grenading one in the name of his particular invisible man
)
