No, we were talking about batteries, and how the theoretical limits of battery energy density isn't even close to the energy density required by long haul trucking. You triumphantly declared that Lithium Sulfur has a theoretical max (which you'll never get to, BTW) of 2600 wh/kg. I used that opportunity to compare it to Methanol, which has already been proposed as a green fuel (it is a common form of biofuel), and already discarded by the long haul trucking industry due to energy density concerns. If methanol isn't good enough, batteries aren't even close. I don't know if you are getting your Hyrogen facts from some special Cult of Elon fact repository, but you're wrong. Again. Hydrogen is 39000 wh/kg, not 2800. That's why it is a potential solution, where batteries never could be.
