Larger scale adoption feels a way off – but economics could stack up favorably in some settings compared to options such as electrification and using e-fuels.

CO2 processing plants to separate out the commercially valuable methane. In the 1970s, that CO2 found purpose in advanced oil recovery. Now, carbon cap- ture and storage (CCS) is reducing upstream CO2 emis- sions, with more applications to come.

The processing technology is being adapted from on- shore, but no one solution is likely to ft all given the wide range of locations, facility sizes, and infrastructure support.

There have been encouraging results in post-combustion
