There seem to be some indicators that power station size fuel cells may

solved.

What?

You seriously think that fuel cells are more efficient than
pump-storage?

Probably. Electrolysis can be better than 90% efficient. Fuel cells
about 60% but getting a lot better. By the time the units I'm referring
to are shipping, better than 90% seems to be indicated.

What do you get out of pumped storage ?
