ClearSign Technologies Corporation Provides Full Year 2022 Update

TULSA, Okla., April 6, 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 provides an update on operations for the full year ended December 31, 2022.

"We are encouraged by our recent sales, and that we are getting products out into multiple industries which will provide references to support our ongoing sales efforts," said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. "As we progress with the production installations of our twenty-burner for a California refinery, we continue to get positive industry feedback."

"The recent traction with our boiler burner product, including sales into two states, California and Texas, is an important milestone for us. We believe that success will breed more success as we complete additional installations in the field. Finally, the success we have had with the development of our 100% Ultra Low NOx hydrogen burner demonstrates that we are continuing to evolve our technologies for current and future commercial applications," concluded Dr. Deller.

Recent strategic and operational highlights during and subsequent to the end of the year 2022 include:

Successfully Completed Final Multi Burner Testing and Demonstration Phase for 20 burner California Project: The final witness testing was completed in the presence of representatives of our customer and also the global engineering company supporting this project. The burner data met all requirements, and the data has been sent to the local air district. This project continues to move forward and the company is scheduled to complete manufacturing for delivery to the job site later this year.

Completed Successful Phase 1 Testing of Ultra-Low NOx 100% Hydrogen Burner: With this completion of the Phase 1 work, the Company will submit a follow-up proposal with testing data and documented industry support to continue the development work with a Phase 2 grant. The application is for the maximum Phase 2 grant funding, which can be up to $1.6 million over a two-year duration.

Entered the Texas Gulf Coast Market with Burner Sale to Global Chemical Company: The Company announced the first sale of its fire tube boiler burner technology into a non-boiler heater of a global chemicals company in the Texas market. The boiler burner will be installed into a process heater, which is replacing an existing heater and SCR (Selective Catalytic Reduction) system. Both heater and burner were sold by Tulsa Heaters Midstream, a fast growing and innovative heater provider based in Tulsa, Oklahoma. The burner is scheduled to be installed in the third quarter of 2023.

Announced First and Second Boiler Burner Sales into the California Market: The first burner was sold into a new business vertical of medical and business waste services and is scheduled to be installed in the second quarter of 2023. The second Boiler was sold to a national service provider of recycling services to the food production and restaurant industries. The boiler burner will be installed with a new boiler and was sold as a package with our partner California Boiler into the San Joaquin Valley Air Pollution Control District of California. This burner and boiler are scheduled to be installed in the third quarter of 2023.
