Something that occurred to me is that usually we create hydrogen from … water. You can do it by different methods, electrolysis being a common one. So I’m afraid we might run into a hydrogen problem before we even get very far along.

Yes it is relatively uncomplicated to make water in a lab setting. I suppose it would be a matter of how much energy you could muster to create enough hydrogen to produce enough water to sustain a civilization. Of course once the water is created there are plenty of ways to recycle it.

But more practically, if we were to truly run out of water, we’re all screwed. The air we breath is laden with water vapor. Without it, it would be quite inhospitable. If we ran out of water, animals, plants and crops would desiccate and die faster than we could create water. Bacteria and microscopic life that is the underpinning of our entire planet’s ecosystem would rapidly dry up and perish. There’s no way we could produce enough to rehydrate the entire planet before life totally collapses.
