Semi

Electric semi has long been in the too hard basket:
● road-freight is low-margin

● making a profit depends on keeping the vehicle moving, which makes long charging times a problem

● battery size & weight is less of a barrier in a such a big vehicle
● battery price remains a problem

● energy & maintenance costs will be significantly lower than internal combustion

● battery swapping has been demonstrated,1 but hasn’t taken off for electric cars – perhaps in this application, high utilization in freight centres may make it viable

● short-haul may be the best application for battery-electric prime movers, at least initially
