I've gotten used to the idea that it seems like if I get a solar roof and power system that I can charge my electric car during the zombie apocalypse, where as AFAIK, I can't easily create gasoline or enough hydrogen for a hydrogen powered car. Right?
Hmms. 2k km isn't bad, but i don't consider this amazing either: my 12-year old big and heavy car can do 1300 km on a full tank. Sure, that's in ideal conditions, but so is this. And there is plenty of simple improvements that would make my car more efficient (weight & aerodynamics mainly). 2k isn't bad, but it's something that ought to be almost achievable with a modern and optimized ICE car as well nowadays.

Hydrogen can be created using electricity and water. Who will create a new battery once yours dies out?
A cheaper and more durable membrane would be a huge improvement on paper. In practice, of course, there are a million variables that make fuel cells difficult to use as a general-purpose tool. From all the issues with fuel storage, cost, mechanical durability, degradation, to problems with pollutants and fouling, and so on...
As a side note: The Toyota Mirai is absolutely fascinating to me. A 1kW hydrogen fuel cell on the open market goes for around $5k, and yet somehow Toyota has managed to put a 136kW stack on the road for under 50 grand!
You can even find one on the used market for around 12 grand. It's almost worth buying them up to use as mobile hydrogen power plants.
What the hell is this weird "news" site? Next article is about MotoGP bikes switching from 2-strokes to 4. That was 20 years ago! And a poor translation at that.. https://www.ruetir.com/2022/10/30/motomondiale-2002-yamaha-y...

Hydrogen is simple to produce if you have access to water and electricity. Gasoline is much harder to do, though.

Hydrogen combustion doesn't produce co2, optimize a petrol-fueled ICE all you want and it's still a problem WRT emissions. I think the assumption is that hydrogen fuel would be produced via "green" electricity sources like wind/solar/nuclear.

Earlier quoted context omitted.
On top of that it’s way more difficult to install a hydrogen charging station than an ev-charging station. On the other hand, in Poland at least, natural gas charging stations managed to get enough traction - every gas station ofers LPG here.
To add, LPG stations are pretty much everywhere in both Canada and the UK as well.
