Plus no range reduction in cold conditions. Plus you can store hydrogen long-term for winter. And transport Liquid Hydrogen with huge energy density per truck/ship to remote places. https://www.thetruckersreport.com/truckingindustryforum/thre... Sounds like a win for northern quartersphere.
China doesn’t feel rich enough to build all of that when charging stations are pretty straightforward and cheap. Probably the only thing holding back electric for long hauls now is the lack of infrastructure (grid is needed to build charging stations, and truckers prefer untolled routes without much of that), and also sunk costs on their existing trucks (which tend to last what feel likes forever with cheap repairs).
Most countries have duty hour limits for safety reasons, as having a trucker drive for 20 hours at a time is a really bad idea. Similarly, they usually have a mandatory mid-duty break.
Combined with the speed limit for heavy-duty vehicles, this provides a clear upper bound on the range any truck needs to have, and today's electric trucks are really close to it - or even exceed this already.
This reduces hydrogen trucks to multi-driver trips (incredibly rare due to the significant additional cost) and multi-day trips without rest stops (Australia?).
Considering that the market is going to be tiny: who's going to buy expensive hard-to-maintain trucks, and how are they going to refuel them? Wouldn't it make more sense to just build diesel-electric trucks and fuel that handful with carbon sequestered diesel?
There's a difference with cars in that people want elegant things for their car. With a heavy truck you can just kind of load a large battery pack onto a platform with a fork lift, or similar.
It’s far too complicated and too expensive, and it’s only selling point (long distance per charge and slow charging) are things that BEVs are continuously getting better at.
Hydrogen continues to be a predatory delay strategy.
Unfortunately, "milking subsidies" has a long and (in)glorious history in the EU.
