TULSA, Okla., December 1, 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, today provides an update on operations for the third quarter ended September 30, 2022.


“We have made good progress moving our commercial and development projects forward,” said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. “Our particular focus has been on the execution of the twenty burner project for a California refinery, where we are currently readying the burners for the upcoming performance demonstration. Recently, we received the concluding purchase order for the California project and we are planning the manufacture of the burners, control systems and spare parts in accordance with our customers accelerated timeline. We have also made progress on the 100% Ultra Low NOx hydrogen burner; we are expecting to move the burner into testing in the near future. Finally, we are pursuing the initial orders of our boiler burner business and firmly believe we will start to see some orders soon.”


Recent strategic and operational highlights during and subsequent to the third quarter of 2022 include:


Received Follow on Purchase Order for California Refinery Multi Heater Project and Moved into Testing: The Company is proceeding with the next phase in the previously announced twenty burner project for a California refinery.  The four burners required for full scale testing and demonstration have now been fabricated and the first has been installed in the test furnace with the optimization of the burners well underway. The preparation is ongoing, and the formal witness demonstration is expected to be completed in the coming weeks.  Additionally, the Company has received the concluding purchase order for the manufacture and supply of the remaining sixteen burners, control systems and spare parts.  We anticipate that the burners will be installed in the customer’s refinery in 2023.


Progressed the Hydrogen Fueled Ultra Low NOx Process Burner Development Project to Testing:   The Company has completed initial “proof of concept runs” with the technology demonstrating the ability to run successfully with fuel comprised of 100% hydrogen. The remaining testing is to demonstrate sub 5ppm NOx over the typical operating range of a refinery burner. The test burner and the other components required for the first planned phase of this testing are manufactured and ready to go as soon as the test furnace, ancillary equipment and personnel resources are available.


Announced an Enclosed Oxidizer Sale to Canada Based Hydrogen Technology Production Company: The Company sold a ClearSign Core™ enclosed oxidizer for installation in a pilot scale hydrogen production plant.  The Canadian customer is developing a breakthrough technology for the production of clean hydrogen.


Announced the Appointment of Energy Industry Veteran Gary DiElsi to the Board of Directors:  Mr. DiElsi is a seasoned energy executive with a broad background of over 40 years of experience in private equity, major global enterprises, smaller industrial companies, and startup ventures, including both turnaround and growth situations.  He is filling Bruce A. Pate’s position.
