CCS is a technology that allows reduction of fossil fuel emissions by capturing CO2 from large emitters (such as coal or gas power plants and the steel industry) and storing it underground.

Gasifying the coal and capturing the CO2 before combustion was not an option; that would have required an entirely new plant like Kemper.

There are enormous assumptions in most calculations, including the assumption that «carbon negative» technologies, like capturing CO2 from power plants burning biomass, can be done at a scale remotely relevant to the climate problem (to be relevant one needs to be talking in gigatons of avoided CO2 emissions per year — each a billion tons).

My colleague Ken Chang, who has written on other concepts for capturing CO2 from the air, is checking this one out.

Now we have another proposal in the carbon cycle that probably has a low efficiency ratio capturing CO2.

My own feel for this is that if we do not achieve global agreement and real action on deep cuts in emissions over the next 10 years or so we will get locked into an inappropriate fossil fuel infrastructure until at least mid-century, that will prevent us from capturing CO2 effectively.

Other higher - tech options include using chemicals to absorb CO2 from the air, or burning plants for energy and capturing the CO2 that would otherwise be released, then storing it permanently deep below the ground, called bioenergy with carbon capture and storage (BECCS).
