Compression ignition requires a suitable ratio of fuel to air.  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.
