    It also requires dedicated infrastructure. EVs can have charging stations at basically anywhere with a power hookup (or a genset. A grocery store here puts small VAWTs to charge off of in their parking lots. And every new-ish building has added charging stations to some of their spaces.

    Hydrogen cars would need refueling stations with dedicated pressurized gas hookups, tanks, and fill machines. And the tanks and the tankers to keep the tanks full.

    Finally the ultimate problem is it’s rather low energy density.

      And all that infrastructure is a problem that doesn’t need solving with EVs. An entire industry we don’t need to build/rebuild

      I thought hydrogen had the highest energy density, like it’s #1 in that metric.

        By mass, sure, but not by volume; and that usually doesn’t take into account the mass of the tanks, and hydrogen is rather difficult to keep from leaking.

        In cars we’re more concerned about volume than mass, in which it performs very low- aluminum as a fuel actually leads that (but is … impractical…)

        For cars, amonia would be the better choice and can be synthesized at home fairly easily. It’s still fairly low energy, though. About the same as hydrogen
