Hydrogen is _really_ hard to store. It leaks from every container, transport and storage losses are just an accepted fact. It might be a good option when we have so much renewables that we can't find any more batteries to shove it in. Then we can use it to store compressed hydrogen, that can be released as electricity from large-scale fuel cells during calm cloudy days.
