I dont mean the technology, it obviously works as evidenced by prototypes 20 years ago. I mean the concept and energy generation/storage, it doesnt make sense as soon as you take more than cursory glance. Hydrogen embrittlement, electrolysis energy loss, ranges, it all falls apart.
Hydrogen production is only going to go up because there are many uses for it. If you want green steel you need to use hydrogen. It will also make sense to use that hydrogen for transportation.
You're in some strange mindset of it being batteries versus hydrogen. It isn't one or the other. It's both.
Honda has been trying to make it happen for 20 years now https://en.wikipedia.org/wiki/Honda_FCX its all a huge failure https://www.autoweek.com/news/green-cars/a36751587/honda-cla...
Whats fascinating is the realization Honda toyed with EVs even longer https://en.wikipedia.org/wiki/Honda_EV_Plus and still managed to fail miserably.
