Sequestration of carbon emissions in the southwestern U.S. requires strategies tailored for its unique attributes. The region under consideration by the Southwest Regional Partnership for Carbon Sequestration includes five states (Arizona, Colorado, New Mexico, Oklahoma, and Utah) and contiguous areas from three adjacent states (west Texas, south Wyoming, and west Kansas). This region is energy rich (net exporter of electricity, coal, oil and gas), has some of the largest growth rates in the nation, and it contains two major CO2 pipeline networks that presently tap natural subsurface CO2 reservoirs for enhanced oil recovery. The ten largest coal-fired power plants in the region produce 50% of the total CO2 from power-plant fossil fuel combustion, and power plant emissions are close to half the total CO2 emissions. This paper outlines the first phase of efforts to reduce carbon intensity significantly, including unique scientific and engineering strategies specific for the southwest.
