The turbine produces high temperatures which then causes reactions with the nitrogen that's present in the atmosphere. There's also nitrogen present in the fuel. It's not 100% pure methane.
> ORNL’s award-winning ultraclean condensing high-efficiency natural gas furnace features an affordable add-on technology that can remove more than 99.9% of acidic gases and other emissions. The technology can also be added to other natural gas-driven equipment.
FWIU basically no generators have catalytic converters, because that requires computer controlled fuel ignition.

FWIU, in data centers,
"100% Green" means "100% offset by PPAs" (power-purchase agreement); so "200% green" could mean "100% directly-sourced clean energy".
Should they pack up and pay out and start over elsewhere with enough clean energy, [ or should force methane generators to comply? ]
It sounds like that's what they're adding for their permanent generators. Unfortunate that their portable "temporary" generators weren't equipped with this technology.
> Elon Musk’s artificial intelligence company is belching smog-forming pollution into an area of South Memphis that already leads the state in emergency department visits for asthma.
I have been to that place and sadly a lot of industrial pollutants in that area. This would make it even worse and the resdients probably won't be able to do anything about it.
