It looks like diesel holds ~10,700 Wh/kg[1]. That’s over 40 times the volumetric energy density.
I hope people find an electrical energy storage system (ie a battery) that’s cheap, and with high mass and volumetric energy density, soon. That would be huge for solving the impending climate (and pollution) crisis.

- SigmundA 5y agoYou must account for all the equipment to convert fuel into mechanical work as well. A battery is a large part of the equipment to covert electrons into useful electricity and electric motors and controller are comparatively light weight. Energy density is still higher I have done rough calculations that say batteries need to be at about 2000 wh/kg to be at parity with a diesel semi and the theoretic upper limit for lithium is 2600 wh/kg.
