I haven't seen any cost models where green hydrogen is feasible without a lot of super cheap excess electricity. And those situations also boost batteries. Do you have one you can show me? It's not just lack of infrastructure, even if you solved the problem of building everything out green hydrogen is still not worth it under conditions close to the present day.

And I didn't say it could never under any circumstances be feasible.

I don't follow your logic here. Nobody went out and built tons of lithium ion batteries for cars until they were actually feasible. We're living in the world where companies wait, and it worked out for electric cars.
