CO2 separation membranes and carbon capture and storage (CCS)

Research output: Contribution to journalArticle

Abstract

An explosive increase of atmospheric concentration of greenhouse gas, particularly CO2, causes global warming and climate change. One of the effective solutions should be mitigation of CO2 emission through the air by Carbon Capture and Storage, CCS. CO2 is separated over other gaseous components at the mass emission sources, such as thermal power plants, and then stored under ground or seabed after transportation by pipeline or tanker truck. For implementation of CCS, the capture cost should be drastically reduced, which is equivalent to develop novel CO2 capture technologies with much lower energy consumption. Among various CO2 capture technologies, membrane separation is promising because difference in pressure or chemical potential between feed and permeate sides drives the separation, and basically additional energy, such as heating in liquid amine scrubbing technology, is not required at all. A number of CO2 separation membranes have been investigated, and herein, the recent progress and the potentiality of membrane separation in CO2 capture are reviewed.
