ClearSign Technologies Corporation Awarded Phase 2 Grant from Department of Energy to Commercialize a Flexible Hydrogen Fueled Ultra Low NOx Process Burner

TULSA, Okla., Aug. 29, 2023 /PRNewswire/ -- ClearSign Technologies Corporation (Nasdaq: CLIR) ("ClearSign" or the "Company"), an emerging leader in industrial combustion and sensing technologies that improve energy, operational efficiency and safety while dramatically reducing emissions, today announces that the Company was awarded a Phase 2 government grant through the Small Business Innovative Research (SBIR) program with the Department of Energy (DOE).

This project is being funded by a government grant through the SBIR program with the DOE to support scientific innovation in clean energy development and climate solutions. This second grant award follows the successful development and demonstration of a ClearSign Core™ Ultra Low NOx burner fueled with 100% hydrogen, which was funded by the Phase I grant amount of $250,000. This Phase 2 government grant award was for the maximum amount of $1.65 million for a two-year duration, which the Company intends to apply to the development of ultra-low NOx hydrogen burner technologies.

"This project has been a great place for us to be able to highlight the capabilities of our ClearSign Core™ technologies," said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. "Adding hydrogen to fuel gas increases NOx emissions, which are toxic, regulated, and limited by the operating permits of our customers. We do believe that in providing the Ultra-Low NOx 100% hydrogen capable burner technology, which is the objective of this Phase 2 grant, we will promote clean air and enable the adoption and growth of the hydrogen economy while enabling our customers to maintain compliance with their low NOx emissions requirements. We appreciate the opportunity that the DOE provides us with this Phase 2 grant, and the ongoing collaboration with worldwide burner supplier Zeeco Inc. that enables us to pursue projects of this scale." concluded Dr. Deller.

The goal of this project is to develop ultra-low NOx hydrogen burner technology, which the Company believes will enable the adoption of hydrogen fuel for industrial heating, leading to reductions in the industrial emissions of both carbon dioxide and nitrogen oxides. Current burners and previous efforts to decarbonize industrial combustion processes through the utilization of hydrogen fuel are inhibited by the lack of industrial hydrogen burners capable of burning pure hydrogen while preventing additional Nitrogen Oxides (NOx) emissions.
