So roughly $100k/(5*120 tons CO2) + 2 million kWh/(5*120 ton CO2) --> 5*2300 Mcf

Ie $167 + 3333 kWh will turn 1 ton CO2 into 19 Mcf

At $0.10/kWh, this is equivalent to paying $500 to remove 1 ton of CO2 from the atmosphere. This goes down to $300 if we assume solar can generate power at $0.04/kWh, particularly off-grid and without need for storage.

And it apparently turns out that the Inflation Reduction Act subsidizes the synthetic natural gas at $54/Mcf, so if we sell about 4.7 Mcf at $64 we've effectively gotten the government to pay $250 to remove 0.8 tons from the atmosphere.

This sounds interesting, as a first step.
