Comment on World’s first crewed liquid hydrogen plane takes off

  The point is that, until electrolysis is cheaper than using natural gas, it will continue to be made with natural gas.

    Yes, but now the onus is moved away from finding a non polluting engine, which needs to be on the moving vehicle, to a non polluting fuel, which can be produced anywhere. And can technically and with proper regulation be produced with no pollution. Which is a lot more than the current state of affairs.

      That’s really lucky for fossil fuel companies who will be making bank on hydrogen, and stalling any research or innovation in green hydrogen. You act like there are no major players making tons of money from hydrogen already, who don’t want electrolysis to gain any ground against the status quo which is making them filthy rich

        Again, this can be achieved through regulation. Regulating the source of hydrogen manufacturing process, for once. If a government wants, it can do it and enforce it.

  It can be, but it takes a huge amount of power to do it, and the biggest hydrogen production method (reforming) produces GHGs itself

    So what? Build solar plants in Africa, pump out hydrogen, keep flying as often as you want emissions free. It is a solution and as such a hydrogen plane is a massive advancement towards a sustainable future for the aviation. Whether it will be such is a different question.

      Make it with nuclear power. Turn water to hydrogen and oxygen. Release the oxygen. Package the hydrogen. Burn the hydrogen and it mixes with the oxygen. Maybe eject the spent radioactive fuel into space some day?

        Disposing of radioactive material via space is not a great idea. Not to mention the cost inefficiencies, the risk of something going wrong with the rocket and spreading nuclear material all over the place is non-zero.
