How? My understanding is that hydrogen is either produced from fossil fuels (aka non-renewable) or from electrolysis but the latter won't be economical for many decades AFAIK.
Worst, all things considered, hydrogen cars are still far less efficient that battery EV: https://insideevs.com/efficiency-compared-battery-electric-73-hydrogen-22-ice-13/ https://insideevs.com/efficiency-compared-battery-electric-7...

To replace diesel and because they've already reached 100% of power from renewables so they're actively looking for other fossil uses they can move to renewable. Germany has some similar projects creating hydrogen as storage for renewables, and replacing some diesel trains with hydrogen. I'm less convinced it will replace petrol, but there is definitely a case for it replacing many uses of diesel.
- benj111 8y agoPetrol is less efficient, but like hydrogen it is more energy dense. And you also have a tank like petrol cars so people don't have to worry about new fangled batteries and running out of electricity. You seem to be over estimating my support for hydrogen. My next car will more likely be battery powered, and I'd be buying battery, rather than hydrogen shares, but it isn't without merit.
