You do realize that basically all the large manufacturers are still working on hydrogen tech. It's going to replace gas ICE vehicles, not EVs. EVs have their place in cities and short transport but they're not efficient enough to work for large machinery or long hauls. There will be a mixture just as we have EVs and ICE gas vehicles now.

If your argument against EV for long haul and large machinery is "inefficiency" then I'm not sure how you're arriving that Hydrogen is efficient. Gaseous hydrogen is very low density, way WAY lower than petroleum. I'll agree that battery technology today isn't the best fit for long haul either. However battery technology keeps getting better. Today's prices are for battery are getting cheaper, lifetime of battery is increasing, and charging times are decreasing.

Hydrogen storage/density has essentially been stagnant for decades. Where is the massive increase needed to support Hydrogen in long haul? Where is the nationwide refueling infrastructure needed for long haul? Hydrogen refueling stations are fewer today in the USA then even just a year ago.

and hydrogen needs to be stored in the vehicle at 70 psi.

[–] Voyajer@lemmy.world 2 points 5 months ago (1 children)

Not 70 psi, 70 MPa (10,000 psi) If we're talking about what toyota is doing with the Mirai.

holy cannoli, you're right! how does that do in a crash?

[–] aleph@lemm.ee 2 points 5 months ago (1 children)

That certainly is news to me. After all these years and the almost total lack of hydrogen infrastructure in the US, I had assumed that it was considered a dead end.

That said, it does makes sense; I hadn't considered that hydrogen tech was more in competition with ICEs than with EVs.

Does ICE means internal combustion engine?
