Premise: I wonder though, would it be possible/practical to use local solar power to hydrolyze water for H2 and use that in a small fuel cell? I get that it is not terribly efficient, but how would that compare to the efficiency of using solar to store energy in a LA battery? My knowledge is limited to college level chemistry and physics, but that was 40+ years ago, so I am basically ignorant. Im a retired mech engineer, did a bunch of stuff: first-gen automated guided vehicles, mobile robots running on battery packs, HF reactors (hydrogen fluoride), etc. So I know enough to be dangerous! IMHO, it is possible to go: Solar >> 12VDC>>hydrolyze H2O to O2 & H2>>compress H2 to 5000 psi for space efficiency and use at night>>regulate H2 to feed a fuel cell (which usually needs some additional chemistry to run too)>>12VDC out>>spin compressor on refrigerator to compress working fluid>>cool/expand working fluid to transfer heat from water >> makes ice for my cocktail
