Abstract: Carbon capture and storage (CCS) is now known to be an effective way to reduce greenhouse gas emissions especially CO2 to the atmosphere. Amino acid salt (AAS) solutions are regarded as promising CO2 absorbents compared to traditional amine solutions, as they are environmentally being with lower evaporation as well as fewer degradation issues. This paper is intended to review recent developments in CO2 capture using AASs. The thermodynamics and kinetics of CO2 and different AASs are illustrated in detail. We will also discuss the blended solutions containing AASs in terms of applications and absorption or regeneration performance. Additionally, we will present specific directions for future research on CO2-AAS systems. This paper could provide a guideline for effective carbon capture by new absorbents.
