President Biden seems nervous about sealing a deal that would improve the health and quality of life of millions of Americans through a stricter rule on truck emissions.
Are there any long haul electric trucks currently in widespread use? No, there really aren’t. Batteries are the reason. If it were economically viable we would see long haul electric trucks. Major truck manufactures make electric trucks. Kennworth and Peterbilt, the two biggest truck manufactures in the united states have electric truck models, and they are only their short haul models. Battery electric trucks are fine for delivery vans, and last mile delivery applications. But long haul trucks do not work with batteries. If these truck makers thought long haul trucks were viable they would make them. They have the technology to do battery trucks.
The technology to do zero emission long haul overland freight already exists. Governments should spend money on that instead of praying that batteries eventually become good enough to maintain the status quo.
I like trains and I’m not American. You brought up energy density as the factor preventing long haul. Please don’t appeal to authority as the argument but rather state what you think the energy density needs to be and why to make electric long haul viable.
The specific energy of batteries are currently an order of magnitude less than diesel. This is not a problem that is going to be solved by a slightly improved battery. The weight of batteries needed to carry long haul cargo makes it a non-starter.
This is also true for cars, but electric cars are viable even though its the same comparison between energy density. Would you be willing to have this conversation with actual calculations and specified arguments regarding the numbers?

I’ll do the calculations if you pay my consultancy fee.
How about we both do the calculations and we cancel each others consultant fees?
