CO2 geological utilization and storage (CGUS) is an important technical means to achieve the goal of “carbon neutrality”. Solving the steel corrosion problem in the process of CGUS is crucial to reduce the risk of CGUS technology and achieve the large-scale promotion and application of CGUS technology. In this paper, the proposed reaction mechanism of CO2 corrosion of steel is reviewed, and the main factors influencing CO2 corrosion of steels are summarized. Moreover, the effects of CO2 partial pressure, temperature, salinity and pH value, the CGUS environment containing impurities, fluid flow and other factors on steel corrosion behavior are clarified, and the main protective measures for CO2 corrosion of steels are summarized. On this basis, the key research directions of steel subjected to CO2 corrosion in CGUS environment are put forward. The directions include further exploration of the reaction mechanism of CO2 corrosion of steels, quantitative study on the coupling effect of various environmental factors on the law and degree of CO2 corrosion, as well as the development and application of corrosion protection technologies under high CO2 concentration conditions.
