What part of that confuses you? Hydrogen is better for cars VS batteries in every meaningful way in 2024. Long range, quick fill ups, zero harmful emissions, don't need to live in SFH or rely on landlord/HOA to grant you the privilege of charging your car.
Hydrogen cell cars are electric cars that don't rely on severely underdeveloped technology of batteries we have today.
You're mostly right. But I don't agree on the last part. Hydrogen production can't be done in your backyard. But electricity can (and I forgive you if have no backyard, these next few points may be less relevant if that is the case).
Unlike hydrogen, electricity production is affordable, scalable, and ubiquitous. And that small detail changes the benefits dramatically.
Again, I can see that these are less compelling points if you live in a super dense area and utilities and supply chain there are really dependable. But this is hardly the case everywhere.
And then there's the build of the car itself. Honestly, I know nothing about it, but something tells me the simplicity of battery and electric motors makes those cars more practical to build, especially if the battery itself is commoditized as part of a complete electric grid solution.
I can put two electrodes in salt water and run it off an old power brick and generate hydrogen. It's not efficient, industrial hydrogen isn't primarily made that way (it mainly comes from oil instead), and hydrogen has a list of other problems, but it can be done.
The trick isn't making hydrogen, it's capturing it, refining it (so that it isn't mixed with a tonne of air), and compressing it into a pressurised storage tank for later use.
None of that is magic, or even especially expensive. You can do it with stuff available off the shelf to a hobbyist. It'd be a silly way to run cars, but you can do it.
