    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.

          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.

          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.

      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.
