Abstract: The U.S. Department of Energy Big Sky Regional Carbon Sequestration Partnership completed drilling the world’s first continental flood basalt sequestration pilot borehole to a total depth (TD) of 1253 m at a paper mill site near the town of Wallula located in Southeastern Washington State. Site suitability was assessed prior to drilling by acquisition, processing and analysis of a four-mile, five-line, three component seismic swath, which was processed as a single data-dense line. Analysis of the seismic survey data indicated absence of major geologic structures that would preclude CO2 injection at the site. Drilling of Wallula pilot borehole was initiated on January 13, 2009 and reached TD on April 6, 2009. Hydrogeologic information was obtained primarily during borehole drilling/advancement utilizing a progressive drill-and-test characterization strategy. A general decreasing transmissivity trend with depth pattern was observed, which is consistent with results exhibited for Columbia River basalt interflow zones at a number of other deep wells in the region. Based on the comparative results from 10 test intervals, a candidate injection test zone was identified between the general depth interval of ∼828 and 875 m bgs. Over this interval, three brecciated interflow zones were intersected and isolated for CO2 injection. The flow tops have moderate permeability (75 to 150 millidarcies) and are bounded by thick flow interiors that have extremely low (microdarcy) permeability. The borehole configuration established at the Wallula pilot site provides a unique opportunity to scientifically study the reservoir behaviour of three connected reservoir intervals confined between primary and secondary caprock zones. The permitting process for the CO2 injection has proceeded in accordance with formal rules for geologic sequestration projects enacted in June 2008 into the underground injection control program administered by the Washington State Department of Ecology. The permitting process is expected to conclude in October 2010 and injection would begin soon thereafter. Post-injection monitoring includes long-term sampling of water retrieved from the injection zone, shallow groundwater and soil gas monitoring, and PSInSAR. [Copyright &y& Elsevier]

Abstract: This paper presents a summary of the main international and national regulations for geologic storage of carbon dioxide. The international group includes the EU Directives, London Convention, and OSPAR. For the national regulations, three countries were covered in this study: United States, Canada, and Australia. In addition to these regulations, a group of guidelines and best practice manuals were also included in this study. As discussion, although this paper recognizes that current legislations have contributed for the regulation of this technology, it is still necessary the development of new rules in other regions. Industry will not invest in large CCS plants without such regulations because of high CCS costs and large financial risks related to CCS. [Copyright &y& Elsevier]

Abstract: The Midwest Geological Sequestration Consortium, Schlumberger Carbon Services, and Archer Daniels Midland has implemented a comprehensive communications plan at the Illinois Basin–Decatur Project (IBDP), a one million metric tonne Carbon Capture and Storage project in Decatur, IL, USA funded by the U.S. Department of Energy’s National Energy Technology Laboratory. The IBDP Communication Plan includes consortium information, funding and disclaimer citations, description of target audiences, media communications guidelines, paper and presentations guidelines, site visit information, crisis communication, on-site photography regulations, and other components. The creation, development, and implementation processes for the IBDP Communication Plan (the Plan) are shared in this paper. New communications challenges, such as how to address add-on research requests, data sharing and management, scope increase, and contract agreements have arisen since the Plan was completed in January 2009, resulting in development of new policies and procedures by project management. Integrating communications planning, risk assessment, and project management ensured that consistent, factual information was developed and incorporated into project planning, and constitutes the basis of public communications. Successful integration has allowed the IBDP to benefit from early identification and mitigation of the potential project risks, which allows more time to effectively deal with unknown and unidentified risks that may arise. Project risks and risks associated with public perception can be managed through careful planning and integration of communication strategies into project management and risk mitigation.

Abstract: This paper is the first of a series that attempts to assess the possible health and safety risks associated with large scale CO2 sequestration in deep brine reservoirs. The approach is based on analysis of available data on the operational track record from CO2 transportation and injection associated with enhanced oil recovery (CO2-EOR) in the US. This paper is particularly concerned with identification of the main business risks facing a company engaged in geological sequestration. Such risks include both the operational risks of capturing, compressing, transporting and injecting CO2, as well as the risk of accidental, rapid CO2 release from wells (including an analysis of blow out data from CO2 injection wells, worked over wells as well as abandoned wells). Observations of the outcomes from accidents in real pipelines and CO2 injection wells in CO2-EOR projects provide the most concrete basis to predict the future safety of the above ground operations of CO2 sequestration in deep brine reservoirs.

Abstract: Perceptions of the potential of emerging technologies like carbon capture and storage (CCS) are constructed not just through technical and economic processes but also through discourse, i.e. through compelling narratives about what a technology is, what a technology might become and why it is needed and preferable to competing technologies. The influence of discourse is particularly important in the innovation phases prior to commercialization when innovation activities are focused on research, development and demonstration, and when feasibility and costs of alternatives systems cannot yet be tested by market dynamics. This paper provides a state-level comparative analysis of CCS discourse in the U.S. to provide insights about the socio-political context in which CCS technology is advancing and being considered in four different states: Massachusetts, Minnesota, Montana, and Texas. This research combines analysis of interviews of state-level energy stakeholders and media analysis of state-level newspapers. In semi-structured interviews, state-level energy policy stakeholders were asked to explain their perceptions of the potential opportunities and risks of CCS technology within their unique state context. Interview texts were coded to assess the frequency and extent of various different frames of CCS opportunities and risks including technical, political, economic, environmental, aesthetic, and health/safety. A similar coding scheme was applied to analysis of state-level newspaper coverage of CCS technology. Here, the frequency of these different framings of CCS opportunities and risks in state-level print media was assessed. This analysis demonstrates wide variation in state-level CCS discourse and perceptions of the potential opportunities and risks associated with CCS technology. This mixed-methods approach to characterizing the socio-political context for CCS advancement in these four states contributes to improved understanding of state-level variation in energy technology innovation, provides valuable information about energy technology development in these specific states, and also offers insight into the very different sub-national discourses associated with emerging low-carbon energy technologies in the U.S. [Copyright &y& Elsevier]

Abstract: Geologic carbon dioxide (CO2) storage verification tests by the U.S. Department of Energy’s (DOE’s) seven Regional Carbon Sequestration Partnerships (RCSPs) provided the experience base for the Public Outreach and Education for Carbon Storage Projects, a best practices manual, published in December 2009. This paper summarizes these outreach best practices; discusses their application in Aquistore, a greenfield CO2 storage project under way in western Canada; and reviews the implications for applying the best practices to new projects during the Development Phase of the DOE’s RCSP Program.

Abstract: This paper presents the results of a combined biomass combustion and geological carbon sequestration feasibility study in Northern Lower Michigan, USA related to a proposed solid fuel-fired 600 MW electric power plant, the Wolverine Clean Energy Venture (WCEV), near Rogers City, MI, USA. The biomass feedstock resource assessment, focused on low intensity, high diversity forest and agriculture in the proposed plant bioshed (<120 Km), has the potential to provide sustainable, dry biomass fuel well in excess of the maximum annual co-firing potential of 20% and offset as much as 1 Tgy−1 of the estimated annual 5.1 Tgy−1 of CO2 emissions (using 100% western coal). CO2/EOR potential in the Northern Niagaran Pinnacle Reef Trend is substantial. To date, seven reef reservoirs have been converted to CO2/EOR floods and three of these fields are sufficiently mature to project recovery efficiency in excess of 40% of primary oil recovery. Using these observations and historic oil production data CO2/EOR potential, in a region adjacent to a proposed CO2 pipeline originating from the plant site, is estimated to be at least 7.2 Mm3 (45 MMB) of incremental oil. Analysis of produced fluids in the same region indicates 55 Mmt of geological carbon sequestration (GCS) potential in abandoned oil and gas fields. GCS capacity is estimated at 271 Mmt in two, Paleozoic, saline reservoir targets providing a combined GCS (with abandoned oil and gas field GCS) of 326 Mmt in the pipeline study area. Estimated, combined, GCS in the proposed pipeline fairway alone is in excess of CO2 emissions for a hypothetical 50 year design life of the WCEV project burning 100% coal of 255 Mmt. Realization of biomass co-firing potential at 20% would result in a 50 MMt offset of CO2 emissions during this 50 year period. Carbon capture and sequestration, including beneficial use in CO2/EOR, GCS in abandoned oil and gas fields, and saline reservoir GCS Sequestration at 90% of CO2 emissions from the proposed plant for a 50 year design life could result in the sequestration of 229.5 Mmt of CO2. These considerations support the potential for a net negative emissions profile of −24.5 Mmt for a hypothetical 50 year design life of the proposed WCEV project. [Copyright &y& Elsevier]

Abstract: This paper explores the mismatch between the widely held public policy view of the long-term risk profile for carbon dioxide (CO2) storage with the emerging science and engineering of CO2 storage. We review the key issues of fit, interplay, and scalability associated with a trust fund funded by a hypothetical $ 1/ton CO2 tipping fee for each ton of CO2 stored in the United States under WRE450 and WRE550 climate policies. Left to grow unchecked, this hypothetical tipping fee fund would accumulate hundreds of billions to trillions of dollars before it would be expected to pay out claims caused by potential damage arising from CO2 storage. The authors conclude there is no intrinsic value in creating a trust fund predicated solely on collecting a tipping fee. Rather than mitigating the financial consequences of long-term CCS risks, this analysis suggests a blanket $ 1/ton CO2 tipping fee may increase the probability and frequency of long-term risk by eliminating financial incentives for sound operating behavior and site selection criteria–contribute to moral hazard. At a minimum, effective use of a trust fund requires: (1) strong oversight regarding site selection and fund management, and (2) a clear process by which the fund is periodically valued and funds collected are mapped to the risk profile of the pool of covered CCS sites. Without appropriate checks and balances, there is no a priori reason to believe that the amount of funds held in trust will map to the actual amount of funds needed to address long-term care expenses and delimited compensatory damages.

Abstract: This paper provides a preliminary assessment of the potential impact that future demand for groundwater might have on the commercial deployment of carbon dioxide capture and storage (CCS) technologies within the United States. A number of regions within the U.S. have populations, agriculture and industries that are particularly dependent upon groundwater. Moreover, some key freshwater aquifers are already over-utilized or depleted, and others are likely to be moving toward depletion as demand grows. The need to meet future water demands may lead some parts of the nation to consider supplementing existing supplies with lower quality groundwater resources, including brackish waters that are currently not considered sources of drinking water but which could provide supplemental water via desalination. In some areas, these same deep saline-filled geologic formations also represent possible candidate carbon dioxide (CO2) storage reservoirs. The analysis presented here suggests that future constraints on CCS deployment–due to potential needs to supplement conventional water supplies by desalinating deeper and more brackish waters–are likely to be necessary only in limited regions across the country, particularly in areas that are already experiencing water stress.
