Reply to comment by V1kt0r in Rolls-Royce successfully tests hydrogen-powered jet engine | Britain's Rolls-Royce said it has successfully run an aircraft engine on hydrogen, a world aviation first that marks a major step towards proving the gas could be key to decarbonising air travel. by yourSAS
Avgas is used for propeller engine planes, which are mainly flown by hobbyists in rich countries, meaning it's use is not very large scale.
Commercial aviation mainly uses turbine engines powered by Jet fuel, which is not leaded but we burn a lot more of it.
