FutureGen 2.0 Monitoring Systems Design Basis and Technology Selection: Geohydrologic, Geochemical and Geophysical Considerations
Advances in carbon capture and storage (CCS) technology show promise for addressing carbon dioxide (CO2) emissions and global climate change concerns related to coal-fueled energy. The FutureGen 2.0 Project is intended to demonstrate 1) the technical feasibility of oxy-combustion technology as an approach for implementing carbon capture at new and existing coal-fueled energy facilities, and 2) utility-scale integration of transport and permanent storage of captured CO2 in a deep geologic formation. Development of the FutureGen 2.0 CO2 storage site is part of a larger project to design, build, and operate a commercial-scale CCS system capable of capturing, treating, and storing the CO2 off-gas from a 168-MW(e) gross capacity oxy-combustion coal-fueled power plant located in Meredosia, Illinois—a first-of-its-kind, near-zero emissions coal-fueled power plant with CCS. In cooperation with the U.S. Department of Energy, the FutureGen 2.0 project partners will repower a previously retired oil-fired power plant with oxy-combustion technology to capture approximately 1.1 million metric tons of CO2 each year—more than 90 percent of the plant’s carbon emissions. Emissions such as sulfur oxides, nitrogen oxides, and mercury will be reduced to near-zero levels. Safe and proven pipeline technology will be used to transport the CO2 to the storage site and inject it deep into the subsurface through a network of deep-injection wells for long-term storage through geologic sequestration. An evaluation that considered pertinent hydrologic, geochemical, and geophysical processes was performed during development of the testing and monitoring program for the FutureGen 2.0 project. This evaluation informed the technology screening process and, in conjunction with project- and regulation-driven monitoring objectives, was the basis for monitoring technology selection. A summary of the overall monitoring approach adopted by the FutureGen 2.0 project, and a detailed description of the testing and monitoring activities that the FutureGen Industrial Alliance, Inc. will undertake at the FutureGen 2.0 storage site near Jacksonville, Illinois, are documented in a project-maintained testing and monitoring plan. All testing and monitoring activities will be performed in accordance with Title 40 of the Code of Federal Regulations (CFR) Sections 146.89, 146.90, and 146.91 (40 CFR §146.89, 146.90, and 146.91) to verify that the storage site is operating as permitted and is not endangering any underground sources of drinking water (USDWs).
