I'd consider a hydrogen
I'd consider a hydrogen powered vehicle if there was ANY general distribution system for hydrogen to refuel it. AFA "green hydrogen". The infrastructure to produce hydrogen cleanly or not requires electricity. The distribution system for electricity altready exists. The generation, distribution and staorage system for hydrogen doesn't.
SImilarly, BEV adoption will be constrained by after-sales support. Every machine needs service, and that will become Tesla's largest problem before 2030. It can't make metal cars cheap reliable and cheap enough for them to be disposible after a colision.
