Evaluating The Suitability For Co2 Storage At The Futuregen 2.0 Site, Morgan County, Illinois, Usa

FutureGen 2.0 site will be the first near-zero emission power plant with fully integrated long-tenn storage in a deep, non-potable saline aquifer in the United States. The proposed FutureGen 2.0 CO2 storage site is located in northeast Morgan County, Illinois, U.S.A., forty-eight kilometres from the Meredosia Energy Center where a large-scale oxy-combustion demonstration will be conducted. The demonstration will involve > 90% carbon capture, which will produce more than one million metric tons (MMT) of CO2 per year. The CO2 will be compressed at the power plant and transported via pipeline to the storage site. To examine CO2 storage potential of the site, a 1,467m characterization well (FGA#1) was completed in December 2011. The target injection zone for CO2 storage is in a zone of high permeability within the upper portion of the Mt. Simon Sandstone. Confining beds of the overlying Eau Claire Formation reach a thickness of 126 in. Characterization of the target injection zone and the overlying confining zone was based on wellbore data, cores, and geophysical logs, along with surface geophysical (2-D seismic profiles, magnetic and gravity), and structural data collected during the initial stage of the project. Based on this geological model, 3D simulations of CO2 injection and redistribution were conducted using STOMP-CO2, a multiphase flow and transport simulator. After this characterization stage, it appears that the injection site is a suitable geologic system for CO2 sequestration and that the injection zone is sufficient to receive up to 33 MMT of CO2 at a rate of 1.1 MMT/yr.
