All the other H2 issues aside, you're competing with a good, established logistic network in EVs: the grid.
H2 is like any new nuke: you're 10 years out with a ton of subsidy and investment from being a player against the EVs of TODAY. Your price targets to compete will have to anticipate 5-10 years of accumulated economies of scale, tech improvements, etc in EV/grid/alternative energy/storage.
I'd be shocked if a bank would float capital to support that given the uncertainty. Just like I'd be shocked if a bank would float financing to a new major fossil fuel development. It might be BANNED in under a decade.
So no...hydrogen infrastructure is not 20x more. It's probably slightly more expensive than an urban charging station, but significantly cheaper than a rural charging station. And remember: electrical infrastructure is mature...it's not going to get significantly cheaper any time soon. Batteries are the innovation driving EV growth, not the grid.
The only thing that is unambiguously more expensive is the fuel. And it always will be more expensive...but prices are going down constantly. If it costs $100 to drive a truck across the US, why would it matter if it costs $200 to do the same with hydrogen, especially if it means not having to stop for hours at a time to recharge?
The midwest of the US is generally wind-rich. The south and southeast will be solar-rich.
