    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.

      The problem with long distance airliners though is that the turbofan powered engine has such a huge power output that is only possible using a turbine.
