Quintessa has recently conducted an independent review of the subsurface Early Risk Assessment for Carbon Storage Licence CS025 on behalf of the Northern Endurance Partnership (NEP). This continues the support Quintessa has previously provided to NEP through review of subsurface risk assessments for the Endurance store and nearby expansion stores within the Southern North Sea.
The Northern Endurance Partnership (NEP) brings together world-class organisations with the shared goal of decarbonising of the UK’s largest industrial clusters, the Humber and Teesside, as it offers access to the Endurance carbon store in the southern North Sea, which has the capacity to store 450 million tonnes of CO2. Other potential stores nearby Endurance bring the potential storage capacity to around 1 billion tonnes. Quintessa has previously reviewed subsurface risk assessments for the Endurance store and four expansion stores. We have recently reviewed the Early Risk Assessment for the fifth expansion store within NEP’s portfolio, BC42, which is within the CS025 carbon dioxide appraisal and storage (CS) licence area.
The Early Risk Assessment (ERA) is an important step in the appraisal term of the CS licence as it ensures that potential threats to storage capacity and injectivity and any critical risks to the containment of CO2 are identified, uncertainties assessed, and further studies to address those uncertainties highlighted. Quintessa provided an independent review of an ERA and presented a summary of its findings at the ERA Workshop attended by the North Sea Transition Authority (NSTA) and the NEP.
