The road trains I mentioned are diesel truck conversions. It's that simple. Get rid of the original drive train, put an electrical drive train in. Shove in some battery where the fuel used to go. Actually works. On a 165 tonne road trains. Not a hypothetical but in commercial operation right now defying your notions of what is and isn't feasible. Imagine what a truck that is designed from the ground up to do that could do. Probably would do quite a bit better.
Paying 2-3x for hydrogen and depending on infrastructure that simply does not exist yet doesn't even sound like the beginnings of a plan. It doesn't make any economical sense whatsoever. It's a pipe dream financed by companies reluctant to get out of the diesel truck business. By the time energy really gets that cheap, battery electric trucks will have been dominating the roads for decades and there won't be any point in replacing them with less efficient hydrogen trucks. There isn't one now. There won't be one a few decades from now.
- _hypx 3y agoA hydrogen truck is basically the same idea just economically sane and doesn’t have a huge weight penalty. You’re mostly repeating BEV propaganda and it is mostly just close-mindedness. The point is that hydrogen trucks are actually economically viable in this setting. Not to mention that BEVs are a >100 year old technology, and the idea that something that old can maintain a permanent cost advantage over all possible alternatives is a completely delusional idea. This even ignores the fact that fuel cells are electrochemical systems and don’t have any fundamental disadvantages compared to li-ion batteries. FCEVs are literally just a cheaper type of EV.
