And this text:
With battery-powered e-cars, only eight percent of the energy is lost during transport before the electricity is stored in the batteries of the vehicles. When the electrical energy used to drive the electric motor is converted, another 18 percent is lost. This gives the battery-operated electric car an efficiency level of between 70 to 80 percent, depending on the model.
With the hydrogen-powered electric car, the losses are significantly greater: 45 percent of the energy is already lost during the production of hydrogen through electrolysis. Of this remaining 55 percent of the original energy, another 55 percent is lost when hydrogen is converted into electricity in the vehicle. This means that the hydrogen-powered electric car only achieves an efficiency of between 25 to 35 percent, depending on the model.

Also I just found out that over 90% of our hydrogen comes from "natural gas reforming" https://www.energy.gov/eere/fuelcells/hydrogen-production-na...
All the substantial investments I've seen in commercial long-haul trucking are in hydrogen. You have Tesla, Nikola and others claiming they have a long-haul battery solution but they are full of shit. Tesla has already delayed their Semi for 3 years now. Nikola is a joke but even they were pushing hydrogen along with their BEV stuff. And the legacy CV companies are, again, only investing in BEV for short-haul stuff.
