The U.S. Department of Energy’s Office of Fossil Energy Advanced Turbine Program is implementing a research program to develop turbines for coal fueled integrated gasification combined cycle (IGCC) power systems that separate and capturer carbon dioxide (CO2). The program is designed to advance the performance of state-of-the-art turbines and develop new turbine concepts for IGCC systems while at the same time minimize the emissions of criteria pollutants and CO2. This talk will present the technical reasons for a coal based IGCC approach to CO2 capture in a carbon constrained world and opportunities and challenges for the gas turbines in these applications and other issues associated with the geologic sequestration of carbon dioxide.
