Or we invent solar-powered planes. Not feasible yet, but who knows.

  there's one but it's a single passenger unit

  Solar powered planes are a feasible engineering challenge. The engineering challenge is making synthetic aviation fuels from electricity. Once that is solved, it's just a matter of installing production plants in areas were solar is most productive.

  The planes don't have to be solar powered, just electric. Leave the energy generation to the ground. The next problem would definitely be the weight of batteries though.

    This might be where the hydrogen could be useful (unlike for cars where it costs too much).
