Risk Assessment and Management for CO2 Transportation Pipelines

Carbon Capture and Storage (CCS) technologies are still in its initial stage in Malaysia so the existence of CO2 pipeline network relatively small which leads to the unadequate understanding of risk associated with CO2 release. In this project, risk-based approaches are used to evaluate the possible risks may occur when carbon dioxide (CO2) is transported in pipelines from its source to desired destinations. There are two case studies are presented. The first one is the risk analysis of CO2 pipeline network onshore and the second one is about the comparison study of risk between the CO2 and natural gas pipeline in order to raise awareness of the order of magnitude of CO2 risk.
It is found that CO2 pipeline may represent significant risks once a large amount of CO2 is released close to dense population. This project also proposes some mitigation methods of the relevant risks regarding the current practices.
