Abstract: The Industrial Revolution has not only changed the way people live, but also the behavior of the earth and the atmosphere that surrounds it. It is now believed that anthropogenic CO2 is the most significant green house gas (GHG) contributing to more than 50% to the global warming and climate change. In the light of increasing fears about climate change, Carbon Capture and Storage (CCS, the subject of this research work) has assumed growing importance. newlineOne of the major concerns in CCS is corrosion. Dry CO2 is inert to commonly used industrial materials. But CO2 an acid gas will react with water to form carbonic acid which is corrosive. In addition, there is a possibility for MEA and MEG (solvent) to get into the transportation pipeline along with CO2 as an impurity during the scrubbing processes. Moreover, during the injection of CO2 into saline water turbulent flow conditions are formed creating flow-induced localized corrosion (FILC). newlineCurrently there is little knowledge on the effect of impurities on material properties under CCS operating conditions. Therefore, to select appropriate materials for CO2 sequestration network, the present work is taken up to investigate the corrosion behavior of carbon steels (CS I, CS 5LX 42 and CS 5LX 60) and stainless steels (304SS and 316SS) in pure CO2 environment as well as CO2 containing MEA and MEG under simulated flow condition and at atmospheric pressure by measuring mass loss using Rotating Cage. newlineThe corrosion behavior of the metals has been studied using fabricated rotating cage as per ASTM G 184 - 06 standards. To ensure the reproducibility of the results from the rotating cage, the instrument was standardized using synthetic ocean water as per ASTM D 1141.The results obtained from the present study has revealed that CS I performs better than CS 5LX42 and CS 5LX 60 in CO2 environment. Also it is found that 316 SS shows better corrosion resistance than 304 SS in CO2 environment. The surface morphology of the samples was determined by Optical Microscopy and Scanning El
