The problem with hydrogen is the lack of infrastructure. EVs have suffered from the same problem too but are arguably over the hump. Starting from zero again with range anxiety and no fueling stations sounds exhausting.
Electric grid capacity will be an interesting field to watch over the next 2 decades.
It's not like power lines all over the world have massive capacity reserves left. And with heat pumps becoming highly relevant right now for heating homes, there's going to be a lot of additional load on the grid.
Yes, EVs and heat pumps do also offer very useful application as flexible load to consume when supply is high and be switched off when electricity supply is low. But all this combined will make electric grids even more essential for keeping everyday life running.
H2 on the other hand with its inherent buffering effects would take some of these pressures off the electrical grid.
I found it interesting how Canada uses LPG even though the winters get cold enough that LPG isn't usable. I lived in Alberta for a year and they had a warning that when it got below -40 the buses would not run. School was not cancelled when this happened, you had to find an alternate way to get there. They did helpfully remind you that exposed skin would freeze in about 5 minutes.
I had an LPG car in Poland, and winters were non-issue. Just had ti start it on regular fuel and switch to lpg after a minute or two - once the engine warmed up.
Diesel vehicles begin to fail at about -10ºC so -40º is an improvement there.
There are extreme temperature vehicles that can handle below -40º with tank heaters and other things, but my gasoline cars started just fine at -40º and they weren't even garaged.
