California Regulator Proposes ClearSign Demonstration With Major Refiner

South Coast Air Quality Management District Technology Committee Approves Project and Sends to Board for Final Approval

Seattle, WA /PRNewswire/ - ClearSign Combustion Corporation (NASDAQ: CLIR), a leading provider of industrial combustion technologies that deliver unmatched reduction of pollutant emissions while improving operational costs, today announced that the Technology Committee of the SCAQMD on July 21, 2017 has unanimously approved and sent to the governing board the recommendation of staff that ClearSign's Duplex technology be demonstrated at a major refinery in Southern California.

SCAQMD staff cited their support for the effort as a means of improving air emissions without the use of harmful chemicals and reagents which are required in Selective Catalytic Reduction (SCR) for control of oxides of nitrogen (NOx), a criteria pollutant that is a precursor to photochemical smog. SCR is the current state-of-the-art in pollution control equipment and is designated as Best Available Control Technology (BACT). The board will consider the request at their next meeting September 1, 2017. If approved, the demonstration will occur at a Southern California refinery on an industrial boiler and involves demonstrating the company's Duplex technology within the customer's operations.

ClearSign's Chairman and CEO, Stephen Pirnat stated, "The California Regulator's recognition of the tremendous potential for ClearSign Technology to dramatically reduce emissions and the associated costs to improve air quality is very encouraging to the engineers and scientists at ClearSign, who have worked diligently to develop this game changing technology."
