New clean-coal technology fires country's cleanest power plant

摘要

A new clean coal technology has been developed that eliminates more than 99.99 percent of the particulate matter that is released when coal is burned. The Advanced Hydbrid filter system is in operation at the Big Stone coal-fired plant in South Dakota. The technology was developed by the Energy and Environmental Research Center (EERC) at the University of North Dakota in cooperation with the U.S. Department of Energy (DOE) and W.L. Gore Associates as well as the power plant's owners. They are Otter Trail Power, North Western Energy and Montana-Dakota Utilities. The DOE contributed 6.5 million dollars to the research. The plant's owners funded the remainder of the 13.4 million dollars cost.
