fuel cells have trouble being cheap, lightweight, high efficiency, and long lasting, all at the same time. I think this could have better scaling on all those dimensions, plus could use natural gas or propane or other fuels for when you don't have hydrogen

Flow batteries?

Not light weight (for stationary batteries, does that matter) but tick the rest of the boxes
