Ah ha, now I've found something! Get a load of this.
"While hydrogen can also be produced by high-temperature steam electrolysis,"
So my idea does have validity! This guy is doing it with high temperature (think solar concentrators) and membrane technology.

Hydrogen production by high-temperature water splitting using electron-conducting membranes
I can envision a world where natural gas is replaced by hydrogen.
to quote further: "Water disassociates into oxygen and hydrogen at high temperatures, and the disassociation increases with increasing temperature"
Yep, my thought exactly,
It's looking doable again!
