Sure, but hydrogen fuel cell cars ARE electric vehicles. While you can burn H2 to make an engine provide transportation, no one is talking about that, really. Batteries can be configured in many ways to make big and small personal cars/trucks. You can’t really fit significant high pressure H2 tanks in as many form factors as you can batteries. And to make fuel cell cars practical you need just as many places to refuel as you need EV chargers. Actually more (adjusted for refuel time) since you can’t slow charge at home or work. So it is just not a technology that can possibly overcome the lead that EVs have. The only possible advantage is faster refueling and that is incrementally being reducing with advances in batteries.
H2 disadvantages for cars:
- need more costly infrastructure than EV chargers
- fuel more expensive based on thermodynamics (this is the killer)
- fewer useful car/truck form factors
- can’t charge at home
- difficult or impossible to get fuel when stranded on empty
- need to replace H2 tanks in old cars
- still dependent on fossil fuels since they require 3-4x as much green electricity per mile
So for other, possibly industrial uses may be the only viable good use cases for H2.
Maybe things like steel or cement production where H2 could be produced on site or nearby.
