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.

  There's vastly more nitrogen in air than in methane. The ratio of air to methane in a gas turbine is also high, over 15:1.

Does AGR Acidic Gas Reduction work with methane turbines? Shouldn't all methane-powered equipment have this AGR (or similar) new emission reduction technology? From https://www.ornl.gov/news/add-device-makes-home-furnaces-cleaner-safer-and-longer-lasting https://www.ornl.gov/news/add-device-makes-home-furnaces-cle... : > 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.

    Though it's not a methane leak, in their case the problem is the poisonous byproducts of combustion FWIU; Looks like methane.jpl.nasa.gov isn't up anymore? https://methane.jpl.nasa.gov/ https://methane.jpl.nasa.gov/ We invested tax dollars in NASA space-based methane leak imaging, because methane is a potent greenhouse gas. Is this another casualty of their distracting, wasteful, and saboteurial hit on NASA Earth Science funding?
