CCS world projects: Cincinnati Arch
Project Overview
Duke Energy has volunteered to take part in a field test of a promising technique for permanently storing carbon dioxide deep under its East Bend Generating Station. The test is one of several being conducted in the Midwest by the Midwest Regional Carbon Sequestration Partnership (MRCSP). The demonstration will involve injection into one or more deep saline reservoirs in the area, including targets in the Mt. Simon Sandstone which underlies much of the Midwest region. Reservoirs in the Mt. Simon formation are located 1.2-2.1km below the surface. As is the case in all of our deep saline injection tests, these reservoirs are located well below drinking water supplies, which are about 30 meters deep in this part of the Cincinnati Arch. If the site is suitable, a small amount of carbon dioxide (about two or three tanker trucks per day over a period of a few months) will be injected through a well at the site. The CO2 may be obtained from a regional supplier. There is also the possibility of using CO2 from a planned, regional demonstration of a CO2 capture technology called oxyfuel technology.
