Carbon capture and storage (CCS) technology is considered to be one of the key technologies to reduce CO 2 emissions. This paper reviews the industry corrosion accidents of CCS transportation system, in which the pipeline corrosion risk is analyzed, and the pipeline corrosion theory is summarized. Also, the effect of impurities on gas phase properties is discussed. We analyze the corrosion mechanism of multicomponent impurities on metals in a supercritical CO 2 environment from the aspects of corrosion rate and corrosion products. We also describe the mechanism of pitting and stress corrosion of metals in a supercritical CO 2 environment. Besides, the formation mechanism of FeCO 3 protective layer and the research status of corrosion resistant alloys in supercritical CO 2 are reviewed and analyzed. Finally, a series of shortcomings and prospects of the current research are put forward.
