2 WESTCARB overview The West Coast Regional Carbon Sequestration Partnership is: A team of researchers from more than 90 organizations comprising: Resource management and environmental protection agencies National laboratories and research institutions Conservation nonprofits Climate project standards organizations Energy and pipeline companies Colleges and universities Trade associations Consultants Led by California Energy Commission (CEC) Funded by U.S. Department of Energy, CEC, and industrial partners 2

3 WESTCARB: one of seven DOE Regional Carbon Sequestration Partnerships (RCSP) An applied research program in three phases: Phase I (complete) focused on regional characterization of CO 2 storage capacity and cost Phase II (underway) focuses on CO 2 storage technology validation via small-scale field tests Phase III (beginning) is focusing on precommercial (large-scale) geologic CO 2 storage field tests DOE program represents 43 states, 4 provinces, and more than 350 organizations 3

4 WESTCARB screened sedimentary basins and estimated CO 2 storage capacities Estimated CO 2 Storage Resource: California Sedimentary Basins Low Estimate High Estimate Billion metric tons CO Gt onshore saline formation capacity Gt natural gas reservoir capacity Gt oil reservoir capacity 4

5 WESTCARB s current basin characterization work focuses on: Characterizing California s offshore subsurface environment for CO 2 sequestration Examining salinity in select formations in the southern Sacramento Basin; characterizing the distribution of hydrocarbon pools in several gas fields in the southern Sacramento Basin Characterizing sedimentary basins in Alaska 5

6 WESTCARB is also conducting an NGCC-CCS retrofit study for California Approximately 50 F-Class (and a couple of H-Class) gas turbines have been commissioned in California since 1998 Which units could be considered candidates for future CCS retrofit? Supportive site characteristics for CO 2 capture Dispatch mode and remaining life Proximity to storage or transport Working with PG&E, which is developing a GHG compliance strategy California s NGCC Plants in Relation to Areas of Potential Geologic Storage 6

7 WESTCARB field projects Terrestrial field pilots in California and Oregon Afforestation Forest conservation Fuels/fire management Four geologic site characterization pilots ECBM/saline in Centralia, WA EOR/saline in Kern County, CA (Kimberlina site) Saline in Solano County, CA Saline in Arizona s Colorado Plateau 7

8 Geologic characterization at the Cholla site in Arizona Installation and testing of a well near the fly ash pond at Arizona Public Service s Cholla Power plant; drilled into saline formations at a depth of nearly 4,000 feet Reservoir characterization suite: Mud logs (0 3,853 ft) Rotary side-wall cores (25) Open-hole logs (Schlumberger) Drill-stem tests of Martin and Supai formations Fluid samples No permeable reservoir options below supercritical CO 2 depth of ~2600 feet Test well at the Cholla Power Plant, AZ 8

9 Kimberlina site characterization Gathered and analyzed seismic data, prior literature, existing well logs, and USGS information Created a 3D geologic model Simulated CO 2 injection into a saline formation Analyzed faults Assessed project risks using two approaches Log from a key reference well Kimberlina l-25 ls 9

10 Kimberlina site characterization modeling There are >1100 boreholes; stratigraphic data from these wells have been incorporated into the model Yellow gas pools are >2600 feet depth; green pools are <2600 feet depth Source: Jeff Wagoner, LLNL 10

11 Simulating CO 2 injection and distribution Parameters: 250,000 tons of CO 2 per year for 4 years into the Vedder formation at ~7500 feet CO 2 plume at 20 years is approximately the same as at 200 years (i.e., immobilization takes place within a decade or two after completion of injection operations) Source: Christine Doughty, LBNL 11

12 WESTCARB s public outreach program Community meetings throughout WESTCARB territory Middle and high school science teachers trainings Contributions to public domain information on CCS Website and interactive carbon atlas Project reports and DOE best practices manuals Support for policymaking IEPRs; AB 1925 Report to the Legislature Technical advisory work for the California CCS Review Panel Independent public perception research by social scientists 12

13 What is CO 2? CO 2 is in the air we breathe and is essential to life plants could not live and the planet would be inhospitable without it CO 2 is not poisonous; it doesn t burn or explode CO 2 is not a water pollutant or a hazardous waste CO 2 helps regulate the climate Too much CO 2 in the atmosphere is contributing to global warming and climate change impacts Carbon dioxide (CO 2 )is fundamental to life on earth 13

14 Principles of public communication Consider the audience s degree of interest, education, and time constraints Address any concerns that have been identified in language and formats suited to the intended audience Word choice Analogies Consider having several types of materials available to match audiences needs Posters, handouts, videos, etc. At-scale stratigraphic column illustrates the depth of CO 2 injection Source: C6 Resources 14

15 Drilling phase communications Developed project-specific webpages describing project scope and objectives and featuring drilling progress reports and site photos Paleogeologic profiles for each formation explained natural history of the area Local newspaper ran several articles on the project; webpages featured on the blog of the Arizona State Geologist Site tours were held for project partners and stakeholders 15

16 WESTCARB s Carbon Atlas an online interactive tool for querying GIS data Built upon standard ArcView GIS; layers include: Major industrial CO 2 sources Sedimentary basins; oil and gas fields Major populations centers Land boundaries (e.g., federal, state, county, and municipal limits) Features WESTCARB geologic and terrestrial sequestration findings Atlas website: HTML%20Viewer 16

17 WESTCARB research helps inform policymaking for CCS CCS workshops for the 2005, 2007, and 2009 Integrated Energy Policy Reports AB 1925 report to the California Legislature AB 32 framework for GHG emissions reductions Oregon House Bill 3543, GHG emissions reductions (forest sequestration) Washington Senate Bill 6001, GHG emissions reductions Nevada Senate Bill 422, GHG emissions reporting 17

18 Permitting: WESTCARB projects have helped establish working relationships with federal and state regulators In California and Arizona, both federal and state regulators have jurisdiction over underground injection permits WESTCARB partners have filed three Class V UIC permits with U.S. EPA Region 9 for CO 2 injection, and one with the Arizona Department of Environmental Quality WESTCARB experience has shown good communication between state agencies and EPA Region 9 Class V permit application filed by Clean Energy Systems for Kimberlina site in

19 WESTCARB provides support to the California Carbon Capture and Storage Review Panel Panel was convened by California agencies (CEC, CPUC, CARB) to draft recommendations on CCS to agencies and the Legislature WESTCARB researchers are serving on the Technical Advisory Committee providing background papers, presentations, and writing support Four or five public meetings of the Panel are being held next meeting is October 21 in Sacramento, CA Final report by the Panel is due at yearend 2010 Panel website: 19

20 WESTCARB s 2010 business meeting is October in Sacramento, CA Open to the public; registration required, but no charge Updates on regional CO 2 storage characterization studies in California and Alaska Updates on state and national regulatory/policy developments Discussion of a new study to evaluate CCS application on naturalgas-fired power plants Results and insights from forestry-based terrestrial sequestration projects Participant-driven discussion of CCS commercialization in the West More details at 20
