Cutting the cost of carbon capture: a case for carbon capture and utilization [PDF]
, 2016 A significant part of the cost for Carbon Capture and Storage (CCS) is related to the compression of the captured CO2 to its supercritical state, at 150 bar and typically 99% purity.

A Novel Swing Adsorption Reactor Cluster (SARC) for cost effective post-combustion CO2 capture: A thermodynamic assessment [PDF]
, 2017 The SARC consists of a number of standalone reactors where a solid sorbent is carbonated by a flue gas and regenerated by a combination of vacuum and temperature swing. Efficiency is maximized through heat integration between carbonation and regeneration
