You are technically correct..... But given a choice between having some small fuel tanks full of biodiesel or some much larger and heavier fuel tanks full of hydrogen; what do you think will work best?

( I assume you realise that it's much easier to run a jet engine on diesel than it is to run it on hydrogen)

All sorts of intelligent people worked on the Microsoft Zune lol

If you want to know why hydrogen wont- work as an aircraft fuel you should Google volumetric energy density

Lol it's almost impossible to store enough hydrogen on a jet plane to fly a long way unless you get rid of the passengers.

This stuff about hydrogen planes is basically green washing

Unfortunately nobody can design a practical hydrogen fuel tank to fit inside an aircraft wing.

Reasons to do with fundamental constraints of engineering and physics.

I mean you could make a tank with insufficient fuel in it or you could make a tank which was extremely heavy, but nobody wants either of those things.

If you want a fly thousands of miles on a jet plane and be green you need to run on biodiesel; This stuff about hydrogen is basically green washing.
