Make hydrogen (H2)with electrolysis. Need to found a good technology for that, and be careful hydrogen is very explosive.

Not sure what I'd do with a bunch of hydrogen. Fuel cells still aren't really a practical thing. I'd thought about maybe some kind of wood-gas biodiesel thing, but I don't know of any way to do that on a small scale with intermittent power.
What stops fuel cells being practical?
I think hydrogen storage is still one of the difficult parts.
Hydrogen storage tank seems to be available but keeping it all under pressure, i've not seen many people talk about that.
