The growing demand for effective greenhouse gas mitigation strategies has driven the development of carbon capture and storage (CCS) technologies, among which BECCS (Bioenergy with Carbon Capture and Storage) stands out for its potential to deliver large-scale negative emissions. In this context, corrosion resistance is a critical requirement for the technical feasibility of CO₂ injection wells, as the presence of water and impurities such as H₂S, O₂, and ethanol can intensify corrosive mechanisms and compromise structural integrity and operational safety. Corrosion-induced failures may lead not only to significant operational costs but also to severe risks of containment loss and environmental impact. In this scenario, rigorous selection of corrosion-resistant materials, coupled with the application of protective barrier systems and the deployment of advanced monitoring strategies, is essential to ensure the long-term integrity and operational safety of CO₂ injection wells throughout their service life.
