1. Demonstration of oxy-fuel combustion in once-through steam generators for CO 2 capture Carbon Capture & Storage Workshop 28 March, 2013 The High Commission of Canada, Canada House, London Prepared by: Mark Bohm (Suncor) Capture Team Member Mark Crombie (BP): CCP3 Program Manager Presented by: Mark Crombie (BP): CCP3 Program Manager

2. The CO 2 Capture Project (CCP) is an award-winning partnership of several major energy companies working to advance the technologies that will underpin the deployment of industrial-scale CO 2 capture and storage (CCS). The CCP is currently in its third phase of activity: CCP Project Overview Phase 1 (CCP1, 2001-2004) technology screening/proof of concept – completed Phase 2 (CCP2, 2004-2009) intensive development – completed Phase 3 (CCP3, 2009-2013) demonstration – on going The CCP is funded primarily by: Member contributions Government grants In-kind contributions

3. 3 CCP Mission Statement “To develop technologies that will reduce the risks of and further advance CO 2 capture and geological storage; making CCS a practical reality for atmospheric carbon mitigation” How does CCP work? Collaboration of leading oil & gas companies, government, NGOs, academic institutions, Current members are BP, Chevron, ENI, Petrobras, Shell and Suncor Over 200 joint projects to date, broad scope ranging from policy to technology development, R&D and knowledge sharing Incorporates oil & gas industry expertise + power industry experience CCP is now a leading authority on CCS, sharing research findings

4. 4 OTSG - Importance of Capture Solution 80-85% of oil sands are currently accessible only through in-situ production methods; these are less invasive than mining and with a smaller environmental footprint SAGD is the leading technology, but is more energy and GHG intensive because of the large steam requirements Current carbon emissions from SAGD facilities exceed 25 Mt/yr, and are expected to be the oil sand sector’s largest source of future emission growth A cost-effective solution for CO 2 capture from once-through steam generators (OTSG) is needed for both greenfield and retrofit applications CCP and its Partners recognize the importance of an economic, retrofitable CCS solution for OTSGs

5. 5 Unparalleled Project Team Expertise Project Lead: Suncor Funding Partners: Cenovus Energy (host site), CO 2 Capture Project, Devon, Praxair, Statoil, MEG Energy Technology Providers: Praxair – industrial gas & combustion technology

6. 6 Potential CCS Solutions for OTSGs Requires solvents; potential source of secondary emissions 90% Capture rate Large steam requirements Commercially available No solvents needed; near zero emissions 99% Capture rate Requires power Need to demonstrate oxy-fuel burners and CO 2 purification AminesOxy-fuel
