It seems an unfair criticism against hydrogen vehicles to hold that against them when the same isn’t done for electric vehicles.

Well the idea is that BEV is more efficient with the energy that it gets...

Which I understand...

But what I don't understand is what part of our usage is actually "efficient" from the get go? Also that 'extra' energy we lose to the electrolysis process could easily be made up with extra solar/wind/renewables... and Nuclear without much issue.

Further, desalination mechanisms are desperately needed for our water problem too... Guess what process can help with that... cough totally not electrolysis cough. It's almost like it's a win all around... Yet everyone is super against it for one nebulous reason or another... and none of those reasons ever make sense to me.
