Ah, so you did bother reading to the end.
I'll agree that H cars are not useful at the moment, but if you wait 25
years and have nothing ready you'll be in the ****.

If companies do no research (and these things will be tiny parts of their
budgets), they get left in the past quite quickly.

25 years ago we were doing work on coal gasification, on the premise that
both oil and natural gas would have been used up by the late 1990s, and that
we would need to use the Fischer-Trosch process for road fuel. I still
prefer the idea of bio-diesel.
