ADA-ES, Inc. (NASDAQ: ADES) (“ADA”) today announced that Dr. Michael Durham, President and CEO of ADA, joined Minnkota Power Cooperative CEO Mac McLennan, North Dakota Gov. Jack Dalrymple and U.S. Sen. John Hoeven, R-N.D., on Monday, October 15 th to unveil a clean coal technology project that has provided an opportunity for the Milton R. Young Station to significantly reduce its emissions. Minnkota’s Young Station is the first lignite-fired, cyclone boiler power plant in the country to use CyClean™ technology, which ADA provides through its joint venture Clean Coal Solutions, LLC (“CCS”). The Young Station commenced use of the CyClean™ technology in its boilers in 2011 and continues to use the technology. CyClean™ combustion additives are designed to improve cyclone boiler operations and reduce power plant emissions. At the Young Station, the additives have demonstrated the ability to reduce mercury emissions by 40 percent and nitrogen oxide (NO x) emissions by an additional 20 percent from previous levels. “We are pleased that we have found a cost-effective technology that can help us meet current and future regulatory requirements and further reduce our power plant emissions,” said Mac McLennan, Minnkota President & CEO. “This technology also provides us with another operational tool to deal with the variables of lignite coal and boiler conditions. We are continuing to use and evaluate the longer-term use of CyClean™ additives.” The CyClean™ additives are comprised of two parts. One comes in a granular form and the other in a liquid. The additives are applied directly onto the coal as it enters the Young Station facility on conveyor belts. Jerry Daseler, who heads facility operations and management for CCS, said his group and Minnkota are the pioneers in the production of refined coal using the CyClean™ technology on lignite coal. “We are proud and excited in the results demonstrated thus far and look forward to producing cleaner energy for years to come at the Young Station while taking advantage of North Dakota’s low-cost and abundant coal reserves,” he said.
