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?

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.
