you can't count on the grid's energy mix improving or not getting worse as the vehicle fleet transitions to BEV.
That is a possibility but they have already corrupted hydrogen. Between the two, I will go with the one that can go either way. There's also the fact that EVs are being produced now while hydrogen car production is still a way off, so it's a stall tactic as well
Yet somehow these "fast" charging stations, which aren't as fast or convenient as regular gas stations (and still run at least partially on fossil fuels anyway), have to get built everywhere. If we can't get rid of these stations then let them be hydrogen stations.
They can also be set up anywhere and are much more convenient, I've seen quite a few in residential streets, companies can set them up in their parking lots, etc. You can't treat a compressed gas the same way, even if it's just the canisters. It willl require much more investment in our infrastructure and conversion isn't straight forward.
I think it's cool tech but in our situation and looking at our current needs, pushing for hydrogen right now is a pipe dream fueld by the oil industry.
This is mostly for the car industry though, the same doesn't necessarily hold for the industrial sector.
