> But it's just distraction, because I think the oil industry knows that the hydrogen will come from natural gas for the foreseeable (10-40 years) with some "future switchover" to "green hydrogen".

Hydrogen was always a distraction. Fuel cells have been 10 years away from practicality since the 80s, and hydrogen production was only ever non-fossil-fuel-based in theory. It's 100% a smokescreen to protect fossil fuels.
