A 600 mile battery - say 1-1.2MWh - should only weigh around 10-12K lbs (at 260-300 wh/kg). And you can throw out the 5K lb carbon capture device, and 5K lbs of engine, transmission, exhaust, cooling and fuel system. Add back 500 lbs of electric motors. The payload difference is actually not that significant, certainly not 33% more payload for the diesel+CCS. Such a big battery would be expensive though. I expect most EV semis will have 300 - 500 miles of range. This system sounds good for decarbonizing the diesels that are already on the road though!
