(Obviously both BEV and FCEV need electricity, but that can equally come from renewable. FC has lower wire-to-wire efficiency than Battery, so clearly optimal energy efficiency is not Japan's motivation. Hydrogen refuels faster and a full tank gets you much further, but the tank is very bulky.) Wondering given it's Japan and they keep stressing "resource-poor", is hydrogen FCEV less susceptible to embargoing on metals by China than BEV?
