Abstract
An optimized monitoring system for geological CO2 storage must be built on knowledge from multiple disciplines and the involvement of multiple stakeholders. In this work we demonstrate a transdisciplinary approach to secure the technical, operational, economic, and societal embeddedness of the solutions for monitoring geological storage of CO2. The Analytical Hierarchy Process (AHP) framework was chosen since it enables group discussions for selecting the relevant criteria, it enables assessment of the monitoring solutions by multiple experts, and not least is a transparent and structured framework for decision making. A synthetic brine-filled storage site representative of the Norwegian Continental Shelf was defined as a test site for the study, and a set of three realistic monitoring alternatives was defined by experts, considering the risks and features of the site. The study was also informed by the Societal Embeddedness Level (SEL) which is a novel methodology designed to assess the societal requirements necessary for the successful deployment of technological innovations, particularly those impacting the environment.
