ClearSign Technologies Corporation Receives Department of Energy Grant to Develop Ultra-Low NOx Hydrogen-Powered Process Burner


Grant to support scientific innovation in the development of clean energy and climate solutions

Tulsa, Okla., May 24, 2022 /PRNewswire/ — ClearSign Technologies Corporation (Nasdaq: CLIR) (“ClearSign” or the “Company”), an emerging leader in industrial combustion and sensor technologies that improve energy use, operational efficiency and safety while dramatically reducing emissions , announces that the company has received a government grant through the Department of Energy’s Small Business Innovative Research (SBIR) program.

The aim of this project is to develop an ultra-low NOx hydrogen burner technology that will enable the use of hydrogen fuel for industrial heating and lead to a reduction in industrial emissions of carbon dioxide and nitrogen oxides. Current burners and previous efforts to decarbonize industrial combustion processes through the use of hydrogen fuel are hampered by the lack of industrial hydrogen burners capable of burning pure hydrogen while preventing additional nitrogen oxide (NOx) emissions.

“We are grateful to the DOE for this grant and for recognizing the potential of ClearSign Core™ technology to provide burners for the evolving hydrogen economy, which has the potential to have significant global impacts, while reducing the pollutant emissions required to maintain a healthy environment of today,” said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. “We have previously demonstrated our current ClearSign Core burner technology in full operation with over 80% hydrogen in the fuel gas and are confident that we can are committed to providing low-emission burner technology to meet the needs of the evolving hydrogen-powered industrial burner applications,” continued Dr. Deller gone.

The project and funding will be in phases. The initial grant is approx $250,000 The project will last six months from the end of June. If necessary, and upon completion of Phase 1 work, the Company may submit a follow-up proposal to continue development work with a Phase 2 grant. Phase 2 grant funding can be up to $1.6 million for a two-year term.

Through the SBIR/STTR program across the federal government, small businesses fuel the US economy and create thousands of jobs, both directly and indirectly, the DOE notes. DOE Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) Awards aim to convert DOE-supported scientific and technological breakthroughs into viable products and services. The awards also support the development of specialized technologies and instruments that aid in scientific discovery.
