I don't think hydrogen will ever be a thing for personal cars. Apart from the abysmal "well to wheel" efficiency it's also just such a hassle to create a fuel network for it. Gasoline is bad enough but a gas that will just leak away whatever you do seems like a stretch. It is just so much simpler with electricity. Pretty much every gas station already has it. No driving it around with trucks. Just maybe once install a bigger cable or a battery/capacitor.

Yet the market still thinks differently. Lots of countries still keep subsidizing EV despite them already being mature technology for such a long time.

We didn't have to subsidize the smart phone to make it successful, we shouldn't have to subsidize electric cars either.

My understanding is most hydrogen fueling stations produce the hydrogen onsite via electrolysis of water.

EDIT: My understanding was wrong - it's produced locally onsite but via steam-methane reforming: https://www.energy.gov/eere/fuelcells/hydrogen-production-na...

I always figured it would make more sense for hydrogen to be an option for renewable infra if the problems with leaking and embrittlement could be solved. Currently, moving renewable power over very long distances and storing it at scale is a non-trivial issue which hydrogen could help solve.

This way, for example, Alaska in the winter could conceivably get solar power from panels in Arizona.

Gaseous form is a problem, but have you seen the Fraunhofer POWERPASTE? I was optimistic when the news was first announced, but that was a decade ago and of course it's not widely used.

Sure but they don't have electric vehicle recharging electricity.

They have run the pumps and power the lights electricity.
