The key assumptions made are that for CO2 disposal in saline aquifers it is wisest to (1) avoid underground disposal in areas of fractured bedrock and restrict the assessment to parts of alluvial basins that are thick enough to provide a seal against leakage and have sufficient pressure to keep the CO2 in a condensed phase; (2) stay away from active faults whose fracture zones may allow leakage of CO2 from underground injection sites; (3) avoid areas that in the foreseeable future have a reasonably high probability of being explored and developed for mineral, geothermal, or water resources; (4) avoid current urban areas and areas that are likely to experience significant population growth during the 21st century; and (5) avoid restricted lands, such as parks and military reservations. The data sets used in the GIS analysis are made available in the electronic version of this report, so that others may reevaluate the approach with different assumptions and data sets. Purpose: In 2003, the State of California, in collaboration with the States of Alaska, Arizona, Oregon, and Washington, asked the State of Nevada to participate in a regional analysis of CO2 sequestration potential, through both terrestrial and geological approaches. The terrestrial approaches involve growing more biomass (particularly trees), and the geological options include proven technologies, such as using CO2 to enhance recovery from oil fields and disposal of CO2 in saline aquifers, and more unconventional approaches. As the state with the least amount of annual precipitation, Nevada has little potential for growing substantially more biomass relative to states along the Pacific Ocean. In this report we present a preliminary assessment of the potential for CO2 disposal by sequestration in geological settings in Nevada using analysis with geographic information systems (GIS). The key assumptions made are that for CO2 disposal in saline aquifers it is wisest to (1) avoid underground disposal in areas of fractured bedrock and restrict the assessment to parts of alluvial basins that are thick enough to provide a seal against leakage and have sufficient pressure to keep the CO2 in a condensed phase; (2) stay away from active faults whose fracture zones may allow leakage of CO2 from underground injection sites; (3) avoid areas that in the foreseeable future have a reasonably high probability of being explored and developed for mineral, geothermal, or water resources; (4) avoid current urban areas and areas that are likely to experience significant population growth during the 21st century; and (5) avoid restricted lands, such as parks and military reservations. The data sets used in the GIS analysis are made available in the electronic version of this report, so that others may reevaluate the approach with different assumptions and data sets.
