Earlier quoted context omitted.
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...
If you can do that at a meaningful rate you might as well install ev charging and just not electrolyse when cars are charging
This is akin to how almost all power used to charge cars, is not-green. For example, there are still Ng, coal, and other types of power plants. If cars switched to gas, instead of electric charging, then some of those could be shut down.
But the true point, is as we convert to more and more solar, we'll eventually shut down the last of the fossil fuel burner plants, and eventually the cars will all be green power sourced.
Same with h2. Getting non-polling cars out the door and into people's hands, is key. Eventually, where the power comes from will be clean. And really, we're already having issues with power infra, even before AI, so re-purposing Ng pipelines for H2 would be a great thing.
