Carbon capture and storage: a case study of emerging risk issues in the iNTeg-Risk project

This paper describes the iNTeg-Risk Carbon Capture and Storage (CCS) case study including: identification of example hazards in the CCS process including capture, transport, injection and storage; analysis using bow-tie techniques; modification of risk matrix approaches to include potential releases in the very long term from storage sites; use of life cycle analysis approaches; possible key performance indicators (KPIs); and knowledge gaps in terms of addressing emerging risk issues. One of the key features of the CCS case study is the need to include the time dimension in the risk assessment. The assessment needs to include both short-term potential accidents (from capture, transport or injection) as well as very long term risks from storage.
