Coal-fired power plants have continued to make significant progress in reducing emissions of sulfur and nitrogen oxides (SOx and NOx), particulate matter, and mercury since passage of the 1970 Clean Air Act. However, there is a possibility that carbon dioxide (CO2) emissions could also be regulated in the near future to address climate change. Recognizing that current CO2 capture technology is not cost-effective and has not been demonstrated at scale, the U.S Department of Energy’s National Energy Technology Laboratory (DOE/NETL) has initiated a research and development (R&D) program directed specifically at post- and oxy-combustion CO2 capture technologies that can be retrofit to existing coal-fired power plants, as well designed into new plants. The goal of the DOE/NETL effort, which is being carried out as part of the Existing Plants, Emissions and Capture (EPEC) Program, is to develop advanced CO2 capture and compression technologies for both existing and new coal-fired power plants that when combined can achieve 90 percent CO2 capture at less than a 35 percent increase in cost of electricity (COE). An aggressive R&D plan has been established in order to develop multiple CO2 capture technology options, capable of meeting the cost and performance target, at a commercial scale by 2020.
