It’s true, but so is retooling aviation around hydrogen. This is just a prediction but I think before that ever happens, EITHER we’ll have light batteries that are safer and more effective that Lithium OR we’ll have carbon-neutral ways to produce hydrocarbon fuels that can be used with conventional aircraft.
Hydrogen has struck out on personal electronics and ground transportation. Now it’s angling for aviation where its energy density may matter more. But it hasn’t been losing because of energy density.
I see it as people wanting to commit righteous violence. People have violent impulses, but we usually control them. Some people with extraordinary violent tendencies go looking for a place where it’s “okay” to let them loose. This is not the only example.
