Most of hydrogen’s problems are solvable - we can pack a car with hydrogen tanks, make hydrogen with electrolysis, build infrastructure, etc.

The big killer is price. Those hydrogen filling stations aren’t $1000 each like home chargers or $50,000 each like DC fast chargers, they’re something like 2 million dollars each. And you need them everywhere, there’s no home filling to carry most of your usage.

The hydrogen you put in them? You have to pay for not just the electricity that makes it into your car’s electric motor, but all the energy that was wasted along the way:

Nobody’s looking to spend all that money on filling stations, and nobody’s interested in paying 2-3x as much to fill their car.
