Real Engineering did a video about this and committed the same fallacy. Engineers nearly always overlook practicality and chase perfection.
Heres the thing: It's not about efficiency, it's about convenience. Transferring 2700 megajoules of energy to an f150 via gasoline in a few minutes is very convenient, something that would take a Tesla a few hours. If consumers were concerned with efficiency the same way engineers were, we'd all be driving electric hummers and cybertrucks.
Hydrogen isn't aiming to be as efficient as batteries. It's assuming to be as convenient as gasoline, but with little environmental impact.
