ClearSign Technologies Corporation

Awarded Grant from Department of Energy to Develop a Hydrogen Fueled Ultra Low NOx Process Burner


Grant Awarded to Support Scientific Innovation in Clean Energy Development and Climate Solutions


Tulsa, OK. May 24, 2022 –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, announces that the Company was awarded a government grant through the Small Business Innovative Research (SBIR) program with the Department of Energy.


The goal of this project is to develop ultra-low NOx hydrogen burner technology which 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.


“We are grateful to the DOE for this grant and for recognizing the potential of ClearSign Core™ technology to provide burners for the developing hydrogen economy, which has potential substantial global ramifications, while at the same time reducing the pollutant emissions necessary to maintain a healthy environment today,” said Jim Deller, Ph.D., Chief Executive Officer of ClearSign.  “We have previously demonstrated our current ClearSign Core burner technology operating at full scale with over 80% hydrogen content in the fuel gas, and are confident in our ability to provide low emissions burner technology to meet the needs of the developing hydrogen fueled industrial burner applications,” continued Dr. Deller.


The project and funding are in phases.  The initial funding amount is approximately $250,000 and the project will last six months starting at the end of June. If needed, and upon completion of the Phase 1 work, the Company will be able to submit a follow-up proposal to continue the development work with a Phase 2 grant. Phase 2 grant funding can be up to $1.6 million for a two-year duration.


Through the SBIR/STTR program across the federal government, small business powers the U.S. economy and generates thousands of jobs, both directly and indirectly, the DOE notes. DOE Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) awards aim at transforming DOE-supported science and technology breakthroughs into viable products and services. The awards also support the development of specialized technologies and instruments that aid in scientific discovery.
