  The point is that, unlike kerosene, hydrogen can be made using clean energy

    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

    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?

  Was this one though? It says they’re using Air Liquide, and here’s a quote FTA:

  Something else a future of clean-burning, hydrogen-powered aviation requires is — other than the actual fuel — is refuelling infrastructure. For Project HEAVEN, H2FLY has been working with Air Liquide.

  For the French industrial gas supplier, which is betting heavily on green hydrogen as part of the future energy mix, it is also about demonstrating viability and shoring up industry demand. “This is the very first time we have brought liquid hydrogen to be refuelled at a commercial airport,” said Pierre Crespi, Innovation Director at Air Liquide Advanced Technologies.

  (Emphasis mine) if it’s green hydrogen, doesn’t that mean it was made using clean energy (as opposed to gray hydrogen)?

    I wouldn’t bet on a company telling you that they’re using “green hydrogen” to be doing anything other than pulling the wool over your eyes. There’s a reason the fossil fuel industry is heavily invested in hydrogen and pro hydrogen propaganda. Once you start noticing it becomes really obvious

      In this very specific area, though, it’s like a badge of honor. If it was Shell or Exxon, lol no. And you’re right to be skeptical. But for the Fuel Cell airplane company, they specifically sought out a company who could provide green hydrogen because that is their goal and motivation. There are some companies who do provide this service for the same reasons - they genuinely care about the climate crisis and want to change things. They “nerd out” about being able to do this, for lack of a better expression. If you’re ever in a room with a lot of them, it’s very obvious.

    Air Liquide is the supplyer of the hydrogen. You have green and blue hydrogen. One is produced with reformation and carbon capture while the other one is produced with electrolysis. So, if the electricity is from renewable then it’s technically zero emission.

      Yes I understand that. OP said it wasn’t, and the article didn’t say specifically what was used for this flight, only that Air Liquide wants to use green H2 for this project.
