Abstract
Carbon Capture and Storage (CCS) is critical for reducing CO2 emissions, but pipeline corrosion caused by impurities in captured CO2 streams poses significant challenges. Impurities such as water (H2O), oxygen (O2), sulphur dioxide (SO2), nitrogen dioxide (NO2) and hydrogen sulphide (H2S) increase the corrosivity of the environment, affecting material integrity. This review provides a comprehensive analysis of how these impurities impact pipeline integrity, focusing on their individual and synergistic effects on corrosion behaviour. Special emphasis is placed on corrosion scale formation, the role of water and acidic contaminants and the interactions between impurities under different operating conditions such as temperature and pressure. Additionally, the review highlights critical knowledge gaps and identifies areas where further research is required to develop effective mitigation strategies.
