> so the cost of CO2 capture has to be well below $110/ton

they say $250/t in the article, but could you expand how you came to "A ton of natural gas requires 2.75 tons of CO2"? Where 1.75t of CO2 is disappearing in result?

Molecular weight of methane (CH4): 16

Molecular weight of CO2: 44

One molecule of CO2 is needed to get the carbon atom to make one molecule of methane.

44/16 = 2.75

The 1.75t of CO2 that went missing is the oxygen, which obviously isn't in the methane.
