Natural gas is substantially more dense, easier to store, and can be produce from carbon neutral sources.

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.

So... Fossil fuels lmao
CurtisLeow t1_iybmdzp wrote
Fossil fuels are fossil deposits. Some natural gas comes from fossil deposits. There are renewable sources of natural gas, just like there are renewable sources of hydrogen. Although currently most natural gas, and most hydrogen comes from fossil deposits. Most hydrogen isn’t carbon neutral either.

Lol natural gas is fossil fuels mate. You burn it for energy which creates carbon.
Try again.

I literally linked a Department of Energy article on renewable natural gas.

You understand we need to move away from carbon emitting energy right?
CurtisLeow t1_iybwccr wrote
And by that standard, hydrogen isn’t carbon neutral either. The vast majority of hydrogen comes from natural gas, as shown in the other Department of Energy article I linked.

It's still better using hydrogen derived from fossil fuels from the grid, than burning fossil fuel gas after extracting gas from fossil fuel, then burning it as a fossil fuel.
The net benefit is fewer carbon emissions using hydrogen, with improvements later as the grid transitions.
As I said: we need to transition AWAY from carbon emitting energy.
