Carbon capture, use, and storage (CCUS) in geological media can be an important means for reducing anthropogenic greenhouse-gas emissions. Several geological settings are appropriate for geological storage of carbon dioxide (CO2), including depleted oil and gas reservoirs, deep brine-saturated formations, CO2-flood enhanced-oil-recovery (EOR) operations, and enhanced coalbed-methane recovery. The US Department of Energy is pursuing a program to demonstrate CCUS technology through its Regional Carbon Sequestration Partnership (RCSP) program. Introduction The Plains CO2 Reduction (PCOR) partnership, led by the Energy & Environmental Research Center, is one of seven regional partnerships established under the RCSP program. The PCOR partnership region includes all or part of nine US states and four Canadian provinces (Fig. 1) and is made up of many private- and public-sector groups working to identify the most-suitable CO2-storage strategies and technologies, aid regulatory development, educate the general public, and investigate appropriate infrastructure for CCUS commercialization within its region. The Phase-III program includes two commercial-scale projects—the Fort Nelson carbon- capture and -storage (CCS) feasibility project and the Bell Creek CO2-EOR/CO2-storage project. Fort Nelson. The PCOR partnership and Spectra Energy Transmission are investigating CCUS to mitigate CO2 emissions produced by the Fort Nelson Gas Plant (FNGP) as a waste stream from natural-gas processing. FNGP is near the town of Fort Nelson in northeastern British Columbia, Canada (Fig. 2). The gas stream will include up to 5% hydrogen sulfide (H2S) and a small amount of methane (a sour-CO2 stream). The goal is to capture the stream of sour CO2 that is separated by the current gas-processing operations and store it long term in a deep saline formation. Currently, this sour CO2 is processed in an existing sulfur plant to recover elemental sulfur, and the residual CO2 and sulfur dioxide (SO2) are passed through an incinerator before venting to the atmosphere.
