    It isn’t going to overtake electric cars, too inefficient.

    But it might be the future for airplanes, which need a lot more energy density.

      Specifically density by weight. By volume, which is more important to cars, hydrogen also loses.

      Yes also cargo ships and possibly American sized semi trucks. Although semis are right on border of battety vs hydrogen.
