Tesla just launched a long haul truck with 500 mile range. They are not the only ones targeting long haul. The perpetuating myth here is that this is somehow hard or impossible. The reality is that this is just a matter of including a few extra tonnes of battery and multiple companies have trucks on the road that can do this. Which is what Tesla did. They also have a fairly efficient drive train. And a charging system to top this thing up. Early days but it seems like it's starting to become worth the trouble. Nikola advertises a battery electric heavy truck with 330 miles of range. Nikola and Volvo seems to still be pretending that they are going to use hydrogen but at the same time they are selling a lot of battery electric at this point and not a whole lot of hydrogen trucks. Mostly ranges are creeping up to the point where drivers must stop to take a break anyway that is long enough to top the battery up. So, the range anxiety argument is simply not there. It's a pure cost driven thing. And it's not like hydrogen fueling is particularly fast or cheap. Of course, a lot of companies are opting for shorter range trucks because they are much cheaper and because that suits their needs. Long haul electric trucks are more expensive. Because of the extra batteries. So, yes, the sweet spot of the market is short haul, for now. But there's nothing inherently hard about longer range trucks. It's just a cost and supply chain issue. As battery production scales and prices come down further, we'll see more companies dip their toes into long haul. Self driving is a thing that multiple electric truck and van companies are talking about at this point as something that they want to do. It's still pretty far out but it's not that much harder than self driving cars. But as I said, the bigger challenge here is simply replacing fleets which is an inherently slow process. But of course that's exactly where the money is going to be for manufacturers. |

Not entirely unlike existing multi-trailer (used on some roads in Australia), so called Road Trains, but limited to two trailers, the main one and the battery trailer:

the truck would enter the highway, stop at a service station, add a "powerpack" battery trailer, drive until the next station, swap battery trailer as many times as needed, then leave it at the last service station before destination.
