Reply to comment by CurtisLeow in Rolls-Royce successfully tests hydrogen-powered jet engine by je97

Natural gas is just another hydrocarbon. lol. Why even switch from jet fuel?

Well if we’re only going to talk about jet fuel vs natural gas, natural gas burns far more cleanly.

Kerosene can't be produced from carbon neutral sources. Kerosene produces soot. Natural gas-powered aircraft are already a thing, by the way. It's a more common fuel than hydrogen.

As soon as you burn it you're just dumping more CO2 and CO into the atmosphere. How could it possibly be carbon neutral to burn more hydrocarbons?

Because there are both fossil sources and renewable sources of natural gas. That's why it's called natural gas. You produce natural gas. Waste treatment plants produce natural gas. Sabatier reactors produce natural gas. There are multiple carbon neutral sources of natural gas.

you can synthesize methane, aka natural gas, make it from atmospheric carbon and hydrogen, but that would be incredibly energy intensive and only viable if we crack efficient fusion electricity.
