Isn't storage a problem with large hydrogen quantities? I'm not sure what form it takes in storage, whether it's H or H2, but either way that's tiny and it's going to seep out of just about everything.

The round trip efficiency is not good, though, and there are per-power costs too. But for very long term storage, or storage for rare cloudy-calm days over large areas, it's hard to beat.
