>Very naive to just say "it'll never ever happen" when crazier alternatives were introduced before in history.

If you look at the energy loss chain from "wind turbine to wheel" you will see why hydrogen makes no finacial sense where you could use batteries instead.

So for cars batteries are a no-brainer. That's what people usually refer to when they say "H2 will never happen".

However for planes, ships and the chemical and mining/refining industry things look quite differently.
