What doesn't make sense is producing, compressing into tanks, transporting, pumping into tanks again, pumping into the tank in your car. For giant ships and the like makes way more sense to me.

Yes, I think hydrogen is more suited to trucking and that sort of thing in the near term. Far better than loading a semi with massive batteries that take a lot of charge time, and mean you drag them around with you. Using electrolysis takes a lot of power though, so using it for a grid battery doesn't make much sense either.
