Hydrogen means throwing away 2/3 of the energy we generate. Driving on hydrogen can never be less than three times the cost of driving a battery EV, even if someone waves a magic wand and gives you a trillion dollars worth of hydrogen infrastructure for free. It’s not the better option.
We’ve got batteries now that will outlast the vehicles they’re in. You don’t care that the engine in a gas vehicle will only last 30 years or that it’s really heavy and expensive.
EVs also don’t cure cancer. Nobody’s really expecting them to solve problems that aren’t related to vehicles in the first place.
