The only way I’ve seen hydrogen make sense is where it’s made and stored on site for later grid level generation. Transporting it makes very little sense for all the reasons you mentioned. Salt concerns and ammonia have both been discussed as potential storage options. But you wouldn’t move it around. Store it in a fixed location and generate the electricity on site. If you don’t have to move it, hydrogen might make some sense.
