Bald face lie. Less than five percent of coals heating value gets to the
wheels of a vehicle via the electrolysis vector.

It wasn't a lie, it was spot on.

I think you misread it, expecting it to say something else. He's correctly pointing
out that electrolytically generated hydrogen returns about 1/4 x 1/3 of the total
input power to a conventional thermal power station. Burn that fuel in an ICE like
BMW's V12 and you get about 1/4 x 1/4 x 1/3 of the input energy. About 2% in fact !
