The accusation of hydrogen having bad efficiency is just something BEV companies came up with. It is basically marketing FUD. A more realistic analysis will show that there is very little difference between using hydrogen and direct electrification strategies. This becomes much more obvious once you realize that you need energy storage for electrification to work, but this part is conveniently left out of the calculation.

The state of the art on the full cycle has 65% loss. No production ready tech goes below than that.

Once we said that, how you judge this very high losses depends of your personal opinion.

Unless some better hydrogen tech is invented, that won't be useful towards this goal.

It is already below 50% and rapidly dropping. There is no significant difference in efficiency already, and this will vanish entirely within time. BEVs are simply lying about this fact.

Energy storage will require hydrogen energy storage. This is the fundamental problem of direct electrification strategies. They will need vast amounts of energy storage that cannot be solved except using hydrogen.
