Amine-based capture of CO2 for utilization and storage

Abstract

Carbon dioxide capture and storage (CCS) technology is an effective CO2 fixation technology, as documented by the special report produced by Working Group III of the Intergovernmental Panel on Climate Change. Today, this technology has become important due to the threat of global warming and climate change. Furthermore, the development of carbon dioxide capture and utilization (CCU) technology, which reuses the captured CO2, has been prioritized in recent years to accelerate the deployment of “CCUS.” For both utilization and storage, CO2 capture is a key process that determines how efficiently decarbonation is able to meet the global target. Regardless of the maturity of various types of CO2 capture technologies, amines are the most widely used chemical species. This paper contains a brief overview of CCUS followed by a discussion of several aspects of amine-based CO2 capture technologies. Carbon dioxide capture and storage (CCS) technology has become important due to the threat of global warming and climate change. Furthermore, the development of carbon dioxide capture and utilization (CCU) technology, which reuses the captured CO2, has been prioritized in recent years to accelerate the deployment of “CCUS.” Amine-based CO2 capture is a key process for realizing a carbon neutral society.
