4 Carbon Capture and Storage - CCS 1. Capture CO 2 from fossil fuel (coal, gas, oil) and biomass before or after combustion 2. Compress CO 2 into liquid form and transport in ordinary pipelines 3. Store CO 2 in a deep geological structure in a safe and controlled manner 4. Monitor storage to ensure storage behaves as expected and to obtain ETS credit Greatest challenges for CCS: - cost of capture - demonstrate safe storage

5 Post-combustion capture of CO2

6 Oxyfuel combustion capture

7 Chemical Looping Combustion

8 Vattenfall CCS roll-out route to early commercial Pilot plant Schwarze Pumpe Target: Reducing energy penalty Technology commercial by 2020 Capture cost of 20 /t Demo plant Jänschwalde Schwartze Pumpe Oxyfuel pilot plant Moorburg NJV3 Polish PP Buggenum IGCC pilot plant Magnum IGCC

9 CCS Capture Road Map Commercial concept: MW el Test rig: MW th < 3 million Pilot plant: 30 MW th 70 million Demonstration plant: MW el Conceptual investigations Theoretical studies Research Basic principles Combustion characteristics Demonstration of the process chain Interaction of components Validation of basic principles and scale-up criteria Long term characteristics Non-commercial Verification and optimization of the component choice, the process and reduction of risks Must be commercially viable incl. subsidies Competitive in the market at that time No subsidies
