The Nexus of Water and CCS: A Regional Carbon Sequestration Partnership Perspective
The Regional Carbon Sequestration Partnership (RCSP) Program of the U.S. Department of Energy (DOE) National Energy Technology Laboratory (NETL) has formed a Water Working Group (WWG) to advance the understanding of the relationships between water management and carbon capture and storage (CCS). Recognizing that each RCSP has its own unique set of challenges related to water utilization and the implementation of CCS, the WWG is focusing on the identification and examination of the water-related issues that are common to all of the RCSPs as well as those that are specific to each region of the United States. This paper summarizes the framework that has been developed by the WWG to identify and investigate the primary issues that result from the nexus of water generation and utilization and the implementation of CCS operations.Water is of the utmost importance in every step of the CCS process, beginning with the capture of carbon dioxide (CO2) at industrial sources to long after the CO2;is injected into the ground (Figure 1). Water is the predominant source of cooling at the majority of CO2;point sources. These cooling water demands will be increased by the CCS steps that will be located at most CO2;point sources, namely, capture and compression. Furthermore, additional water will also be needed for other capture processes, such as solvent regeneration. However, the largest impact to water use is likely to come from the parasitic load CCS operations may place on existing facilities.View/Download Document
