The problem with hydrogen is that it is used to power piston engines. These are fundamentally inefficient due to the pistons having to stop and start twice with each complete stroke. l]
That's not really why they're so (relatively) inefficient, as the linear momentum (the up and down bit) is not lost, but is converted into angular momentum (round and round ness) by the con rods and crankshaft.
