6 Snøhvit LNG – offshore piped and stored CO 2 Starts in 2007 Piped CO 2 from onshore LNG plant Storing tons CO 2 annually Injecting below reservoir

7 Snøhvit – Gas and CO 2 flow OFFSHORE CO 2 Wellstream ONSHORE

8 Reinjecting tons CO 2 /year

10 Halten CO 2 value chain principles Power plant 2011/12 Heidrun 2018/24 Gas EOR Oil CO2 Capture 2011/12 CO 2 quotas Draugen 2011/12 Electricity Heat Electricity CO 2 Oil Gas

11 An Industrial Solution A win-win-win for: Industry – Large-scale CO 2 for EOR – Improved security of supply Environment – Reduction of CO 2 and NOx emissions through offshore electrification – Industrial utilisation of greener fossil fuel technologies with a global market potential Society – Prolonged field life and increased oil recovery – National electricity grid benefits Society Environment Industry
