World’s first crewed liquid hydrogen plane takes off::undefined
While technically zero emission, 95% of hydrogen is created using natural gas reformation. It’s really really disingenuous to say zero emission when it uses a huge amount of fossil fuels in the creation of the fuel
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)?
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.
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.
That’s not a new plane, that’s the double fuselage version of Pipistrel Taurus: https://en.wikipedia.org/wiki/Pipistrel_Taurus
Pipistrel Taurus is a glider, first flown in 2004. There is an added benefit of using a glider for testing a new engine: gliders have a much better L/D ratio, so less power needed for longer flights, and if there is a malfunction they can land safely while gliding.
Oh, the humanity!
Should have used helium. Works for balloons!
LEL for Hydrogen: 4.0 (% in air)
UEL is 75 %
This is the most severe (wide range) for any fuel.

Good luck with the insurance fees for commercial flights.
