Even if compression in a diesel engine perfectly removed methane from the air, you're not going to process the atmosphere a few hundred cc at a time. To remove methane from the air, I see two options: increase the amount of hydroxyl radical if there's enough methane to deplete it, or as you say build air-cooled CSP plants. For the CSP option you would want a counter-flow heat exchanger and a catalytic converter on the outgoing air.
