Promises of “green hydrogen” and fertiliser made sustainably haven’t panned out. I’ll believe them when I see it, but I’m not a believer in industrial farming, which is more akin to mining.

Green hydrogen can't compete when natural gas-derived hydrogen is allowed to dump its waste CO2 into the atmosphere. That doesn't mean it can't or won't work when natural gas is outlawed. Your evidence shows nothing except that CO2 isn't being controlled.
