Anthropogenic CO2 emissions has led to global climate change and widely contributed to global
warming since its concentration has been increasing over time. It has attracted vast attention
worldwide. Currently, the different CO2 capture technologies available include absorption, solid
adsorption and membrane separation. Chemical absorption technology is regarded as the most
mature technology and is commercially used in the industry. However, the key challenge is to
find the most efficient solvent in capturing CO2. This paper reviews several types of CO2 capture
technologies and the various factors influencing the CO2 absorption process, resulting in the
development of a novel solvent for CO2 capture.
