The problem is you don't really understand the scale of the problem here, and since you have me on ignore, I'm not going to bother getting into the mathematics of it (which I've done before), but I can assure you, the amount of power generation you need to generate the H2 does not workout favourably for H2 over BEV.
No, we don't, but we are far closer to having it than we are to replacing gas stations with hydrogen ones, let alone the generation needed to produce all that H2. BEV's are "easy", because you can charge them at home, so they really don't need the same level of infrastructure that gas and diesel cars need, while hydrogen cars need even MORE extensive (and complex) infrastructure because of its increased level of hazard and considerable challenges with handling and storing it.
This is a lot like the argument that because we are investing in fusion, that we should abandon fission and just ignore all the problems with fusion because a few blokes are claiming it's the future. You could spend a day explaining to somebody why fusion is hard, sustained fusion harder, and net positive fusion harder still, let alone meaningful net positive, but if their argument is perpetually "oh, we'll figure it out, it's the future" at some point you just have to abandon the conversation because the person either can't, or won't, understand the details that underpin the challenges.
