STEMM-CCS

In summary, STEMM-CCS has successfully developed and tested a robust methodology for establishing environmental and ecological baselines under ‘real life' conditions. It has developed a suite of cost-effective tools to identify, detect and quantify CO 2 leakage from a sub-seafloor CCS reservoir, including an assessment of the utility of chemical tracers in the marine environment. Results have enabled the modelling and assessments of the local, regional and wider impacts of different reservoir CO 2 leak scenarios, including the potential role that fluid pathways in the shallow subsurface may play in reservoir integrity, and a decision support tool has been developed to assist operators in monitoring, mitigation and remediation actions. STEMM-CCS has delivered best practice for selection and operation of offshore CCS sites, and results have been shared with industrial and regulatory stakeholders in order to help increase confidence in the physical security of CCS, and to support the..
