“…However, as CGS is built into a natural body (a geological formation) risk can be understood as a combination of natural and technological hazards because some causes of possible leaks do not only depend on the operation of technology as usually happens in industrial plants and consequently the causes are not perfectly known or understood (Morgado and Esteves, 2011). Engebø et al (2013) also bring forward that risks associated with CO 2 capture and transport are satisfactorily managed when planned, different from risk related to storage, for which there is no large operational experience.…”

Carbon geological storage (CGS) projects are designed to securely store carbon dioxide (CO 2 ) for thousands of years. Because of this, there are several studies to evaluate the potential risks of long-term storage of CO 2 in geological formations. This paper presents a new method for the qualitative risk assessment of CGS: the risk assessment of stored CO 2 (RA-CO 2 ) method. It consists of the systematic and structured identification of CO 2 release risk scenarios arising from: seal, well, and fault and fracture zones. The uncertainties associated to each mapped risk scenario and the risks are qualitatively evaluated using the RA-CO 2 method. The characteristics of the RA-CO 2 method enable a comprehensive understanding of the underground evolution and future behaviour of the CO 2 in various time scales and their influence on safety. For future studies, the validation of the proposed RA-CO 2 method using a real case study is recommended.Keywords: risk assessment of stored CO 2 ; RA-CO 2 method; qualitative risk assessment; CO 2 leakage; CO 2 geological storage; CGS.Reference to this paper should be made as follows: Paraguassú, M.M., Câmara, G., Rocha, P.S. and Andrade, J.C.S.
