1 Midwest Regional Carbon Sequestration Partnership David Ball MRCSP Project Manager Neeraj Gupta, Ph.D. Leader, Geologic Sequestration Battelle Energy Technology 7 th Annual Carbon Capture and Sequestration Conference, May 7, 2008 Plenary Overview 1

2 MRCSP s mission: be the premier resource for sequestration knowledge in its region Quantifying CO2 sources, demographics and economics in the region Characterization, Phase I, Reaching Out To and Educating Stakeholders Validation, Phase II, Implementation Developing a Regional Model of the Economics of Sequestration Quantifying CO 2 Sinks in the Region Net Sequestration-Based Emissions Abatement Costs ($/tonne CO2) Geologic Terrestrial Annual Supplied CO 2 Sequestration Capacity (MtCO 2 ) Terrestrial: Potential for 20% annual offset for large point sources Geologic: 100s of of years of of capacity for large point sources in in deep saline alone Geological Terrestrial 2

3 A synopsis of Phase II progress Three geologic injection tests are well underway Completed pre-drilling characterization at all three including seismic surveys. Completed drilling of wells for two sites ~5,000 foot deep injection and monitoring well at Michigan Basin Site ~8,000 foot deep injection well at the Appalachian Basin site (Burger) Completed permitting and injection into deep saline formation at Michigan Site Over 10,000 tonnes of CO 2 injected into Bass Islands Dolomite formation Injection permit for Appalachian site in final stages of review by Ohio EPA Drilling/Injection permit submitted to EPA Region IV for Cincinnati Arch (East Bend) Site. Open house held with 25+ neighbors in attendance A ~9,000 foot deep strat well was completed in Northeast Ohio Piggyback effort (95% funded by State of Ohio). Three terrestrial field projects well underway: croplands, minelands, wetlands. About 20 test plots in operation across the region. This work has established the concept of geologic CO 2 storage in the region and provides an excellent foundation for the Phase III project. 3

10 Piggy Back Program - Leveraging the Oil & Gas Exploration Industry Team up with oil and gas industry to collect data DOE gets access to existing drilling operations saves significant cost (counts as cost share) Oil and gas operators get detailed wireline logs Data go back to build regional understanding of geology and improved capacity assessment 9000 ft deep stratigraphic test well in Tuscarawas County Ohio 10

11 MRCSP Phase III proposed sites TAME Ethanol Plant Duke IGCC Plant Primary site Host: TAME, a joint venture of The Andersons and Marathon Petroleum Plant operational: February Injection start: FY2010 Scale: 1 million tonnes of CO 2 over a four-year period Target: Mt. Simon at ~3500 ft. Optional site Host: Duke Energy Plant operational: FY 2012 Possible injection start: FY 2012 Scale: Possible 2 million tonnes over four-year injection period Target: Mt. Simon at ~8000 ft. Multiple injection zones and caprock layers 11

12 Candidate site plan for ethanol site The TAME Ethanol plant sits on about 80 acres Candidate location for compression plant and injection well site A CO 2 transfer line will be needed to move the raw CO 2 from the vent stack to the compression plant. CO2 Vent Stack 12

13 Ethanol site infrastructure requirements Current spec for compressor plant calls for four 5 to 6-stage reciprocating intercooled units at 1250 hp each (similar to Ariel units shown) Pressure rise: ambient to ~1,500 psig Total flow: ~800 tonnes CO 2 per day Flow control strategy is expected to be via throttled bypass loop A glycol dehydration system integrated with intercooler package is anticipated for moisture control Raw CO 2 from ethanol plant vent stack will be transported to compressor plant via low pressure transfer line Shown is 600 tonne per day line 13

14 UIC Regulatory process anticipated for Phase III ethanol plant site Develop Project Develop project plan Plan Apply to OH DNR for drilling permit OH DNR Issued drilling permit Drill, assess data Develop and complete project well plan design Apply to OH EPA Develop project for UIC Class V plan permit Includes coordination with other agencies and statutes: -Endangered Species Act (U.S. Fish and Wildlife Service) National Historic Preservation Act (State Historic Preservation Office) Wild and Scenic Rivers Act Coastal Zone Management Act (Coastal Management Program Permit application is reviewed by OH EPA Public Comment Period (at least 30 days) on draft decision Permit issued (or denied) Internal integrity demonstrated Injection is authorized to commence Injection is completed Apply to OH EPA to plug well OH EPA terminates permit (well is plugged) Key: MRCSP OH EPA OH DNR NEPA assessment and several other permits will also be needed 14
