Regional Carbon Sequestration Partnership Water Working Group White Paper on the Nexus of Water and Carbon Capture and Storage
Carbon capture and storage (CCS) are promising technologies that have the potential to drastically reduce anthropogenic carbon dioxide (CO2) emissions into the atmosphere. The U.S. Department of Energy National Energy Technology Laboratory has established the Regional Carbon Sequestration Partnership (RCSP) Program, the goal of which is to develop the infrastructure, regulations, and technology for large-scale CCS from a regional perspective. In order to investigate the relationship between water and CCS, members of the RCSPs have formed the Water Working Group (WWG). This white paper, produced by the WWG, summarizes the influence CCS is expected to have on water issues and the influence of water issues on CCS. Water is of utmost importance in every step of the CCS process, from the industrial sources where CO2;is generated to long after the CO2;is injected into the ground. Water is relied upon heavily for cooling, especially in power generation facilities, but is also needed for other processes, such as boiler operation and during the regeneration of solvents used during CO2;capture. Each technique for capture and compression may require water for cooling the additional equipment and for makeup water in the various processes. Currently, a majority of the water used by power plants is provided by surface water and groundwater resources that face competition from agricultural and municipal uses across the United States. The additional water load required for CCS may be problematicView/Download Document
