4 Program Structure International technology development effort. Distinct regional programs in the US, Norway, and European Union. Sharing among programs to leverage results and reduce duplication. Europe EU: 12% Project Funding Cash $25mm + ca. $25mm In kind Norway Klimatek: 13% Industry-CCP Eight Participants: 54% United States DOE: 21% 4

5 CO 2 Capture Project Objectives Achieve major reductions in the cost of CO 2 Capture and Storage: 50% reduction when applied to a retrofit application. 75% reduction when applied to a new build application. Demonstrate to external stakeholders that CO 2 storage is safe, measurable, and verifiable. Progress technologies to: Proof of concept stage by 2003/4. 5

10 CO 2 capture challenges- a few examples! Flue gas is produced in large volumes, at low pressure, with low levels of CO 2 How pure does the CO 2 need to be for transportation and injection Other GHG effects, such as Sox and Nox Retrofitting large equipment into existing plant. Integration of process steps in the production of H 2 and CO 2 capture, at high temperatures and pressures. Capture from either Post or Precombustion when combustion takes place in oxygen rather than air where everything has to work at v. high temps and high pressure. Boilers, heaters and turbines efficiency under the conditions in question. Can all of the solutions be scaled up. Can some steps be scaled down. 10

12 SMV key findings on review of the Stateof the-art (SOA) The industry has many of the competencies and answers we need Decades of experience in sequestering CO 2 in EOR fields Industry has experience in naturally occurring CO 2 producing fields (analogs) in the US In the US and Europe, the natural gas industry has 90 years of experience storing natural gas in 100s of fields CCP should not duplicate significant, third-party research & development worldwide Understanding Geologic Storage, Maximizing Storage Efficiency, and short-term Verification & Monitoring are understood or are receiving significant third-party R&D 12

13 Storage, Monitoring & Verification (SMV) Team Focus Areas Understanding Geologic Storage, e.g. Caprock integrity issues, if any Cost per tonne CO 2 Verification & Monitoring e.g. Does CO 2 migrate? Under what conditions? Can we verify the amounts injected? What tools are appropriate for leak detection? Assess Health, Safety & Environmental Risk, if any? 13

14 Storage: Summary of Progress HSE risk assessment SOA* Learning from acid gas storage Learning from natural analogs Legal aspects of CO 2 storage * HSE Risk Assessment & Methodology HSE risk assessment & methodology guidelines Learning from long term EOR and gas storage Probabilistic study on CBM storage Spectral analysis of plant stress from aerial images Pipeline transportation costs material selection Long Term Monitoring & Others.. CO 2 impact on well tubulars & cement CO 2 detection techniques* Optimum monitoring methods Noble gas labeling to detect CO 2 leak source Modeling CO 2 movement Geological studies Effects of injection on properties of reservoirs and cap-rock 14

19 SMV Communications- Way Forward We don t want to have 40 studies sitting on the shelf Rather, we want integrated series of reports that demonstrate that CO 2 storage can be safe and effective CO 2 can be monitored both short and long-term CO 2 storage is verifiable Have engaged professional communications consultants to help us. 19

20 Communications, cont. We plan to engage a professional association and journal Extensive peer-review world-wide Current vision is for 3-4 key audiences e.g. Scientific Journal, highly technical ( pages) Government Report and Road Show ( pages) Public reader-friendly version (3-10 pages) TV documentaries for BBC, Nova, Discovery Channel Consultant s work proposals in hand Deployed by 1Q
