For commercial remote charging yes for pure generation . GM has a 60 kW solution they use for EV events, and the military is interested. They are 30k lb trailers you tow to location. Problem with H2 is its hard to transport and store, and its a sticky/tricky molecule to work with. Also its not a good electricity solution, as you use electrolysis (work) to create energy (H2) to convert back to work (electricity). Basically its lossy, hard to work with and expensive, so has limited use cases.I think a hydrogen fuel cell back-up generator would be a great idea.
