Hydrogen will have an important role to play in the future of green energy simply because it's a portable high density fuel, that doesn't require a battery to work.
The trade-off is that hydrogen takes more energy to create, then you get back. That doesn't make a lot of sense when you're using fossil fuels, but it would in a future with significant amounts of excess green energy e.g. wind, solar, fusion, etc.
I'm not sure if you're aware of this, but hydrogen fuel cell vehicles do have batteries. You can't put energy captured from regen braking back into the fuel cell, so either you have a battery or you lose a third of your range.
Fuel cell EVs can't be fitted with charging plugs for religious reasons.
I really need to hear that story.
It's a joke about Toyota's attitude towards hydrogen and batteries. Fuel cell EVs almost make sense as plug in hybrids, with 40 miles of battery range for daily use and the hydrogen system for longer trips, but that would be blasphemy against the holy fuel cell!
