It's because hydrogen is a terrible fuel. In theory it could work, but there were so many practical problems with compressing the hydrogen into storage tanks and then keeping it in those storage tanks but the amount of effort you have to go through to make it work completely negates any performance benefits.
But its only exhaust is PuRe wATeR!! /s
It still makes me LOL to see people tout this, when battery EVs don’t exhaust anything.
Alas, battery EV passenger jets are a long way off.
They are without significant improvements in battery technology. Lithium Ion simply doesn't have the energy density to be able to lift its own weight.
There's also the fact that they are too explosive to conform to flight safety standards.
Well I mean so it is kerosene technically
also most hydrogen now is not green at all, the production of it uses methane and releases CO2. only a small percent of hydrogen is truly green, and very expensive.
