Post-combustion CO 2 capture from the power and industrial sectors has gained widespread attention due to its ability to retrofit easily with newly installed and existing plants. This state-of-the-art, updated review provides an overview of technical issues in post-combustion CO 2 capture related to process performance, energy requirements for CO 2 capture, and inconsistencies in the prediction of CO 2 capture cost. Recent updates are presented regarding chemical absorption-desorption systems, and particularly CO 2 absorption and solubility enhancement studies, absorber operation at elevated pressure, recent developments in absorber configuration, and methods for reducing the heat duty of strippers. Furthermore, recently developed post-combustion hybrid techniques such as the membrane-absorbent hybrid process, the membrane-cryogenic hybrid process, the membrane-adsorption hybrid process, the absorption-electrolysis hybrid process, and the solar thermal electrochemical process (STEP) are discussed. Finally, we suggest areas for improvement and indicate that there are significant future prospects for post-combustion CO 2 capture. C
