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

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.
