Hydrogen could be a solution for storage, transportation. And there is a possibility to find a more direct way to produce hydrogen with solar power that photovoltaics and electrolysis.
Correct me if I'm wrong, but it seems that the world has moved away from hydrogen in favor of batteries?
There's the cycle efficiency, but it's probably also a factor that we have a very well developed infrastructure for shipping electrical power around, while pretty much none for hydrogen.

Hydrogen via electrolysis is not a good solution for grid-scale storage. The cycle efficiency is just way too low.
