The U.S. Department of Energy's (DOE) Fossil Energy Program has adopted a comprehensive, multi-pronged approach to the research and development (R&D) of advanced carbon dioxide (CO 2 ) capture technologies for coal-based power plants. Under this program, the National Energy Technology Laboratory (NETL) is conducting research to develop the next generation of advanced capture concepts for coal-based power plants. Research projects are carried out using various funding mechanisms -including partnerships, cooperative agreements, and financial assistance grants -with corporations, small businesses, universities, nonprofit organizations, and other national laboratories and government agencies. Current efforts cover not only improvements to state-of-the-art, first generation technologies, but also the development of second and third generation advanced CO 2 capture technologies. In addition, DOE/NETL is conducting technical-economic analyses to establish the baseline cost and performance for current CO 2 capture technologies and determine the feasibility of advanced capture and compression technologies.The overall goal of the DOE/NETL CO 2 capture R&D program is to develop advanced technologies that achieve at least 90 percent CO 2 capture with a corresponding cost and energy penalty reduction of 50 percent compared to current state-of-the art technologies applied to pulverized coal combustion and integrated gasification combined cycle (IGCC) power plants. Critical R&D targets include the completion of laboratory-and small pilot-scale testing of a broad spectrum of CO 2 capture approaches, including advanced solvents, sorbents, membranes, oxy-combustion, and chemical looping combustion by 2016; completion of large pilot-scale testing by 2020; and full-scale demonstrations of the most promising technologies beginning by 2020. It is anticipated that successful progression from laboratory-through full-scale demonstration will result in several of these advanced technologies being available for commercial deployment by 2030.The purpose of this paper is to provide an update on the R&D efforts of advanced post-combustion CO 2 capture technologies for coal-based power systems being conducted by DOE/NETL.
