  Alas, battery EV passenger jets are a long way off.

    They are without significant improvements in battery technology. Lithium Ion simply doesn’t have the energy density to be able to lift its own weight.

      There’s also the fact that they are too explosive to conform to flight safety standards.

    It’s true, but so is retooling aviation around hydrogen. This is just a prediction but I think before that ever happens, EITHER we’ll have light batteries that are safer and more effective that Lithium OR we’ll have carbon-neutral ways to produce hydrocarbon fuels that can be used with conventional aircraft.

    Hydrogen has struck out on personal electronics and ground transportation. Now it’s angling for aviation where its energy density may matter more. But it hasn’t been losing because of energy density.
