TULSA, OKLAHOMA / ACCESS Newswire / November 19, 2025 / ClearSign Technologies Corporation (Nasdaq:CLIR) (“ClearSign” or the “Company”), a leader in advanced combustion and sensing technologies that help industrial operators dramatically reduce emissions, increase efficiency and safety, and support the use of cleaner fuels including hydrogen, today provides an update on operations for the quarter ended September 30, 2025.
“We are very encouraged by the recent uptick in order flow and we believe it reflects growing market acceptance of ClearSign’s technologies. This gives us confidence that our strategy of product line expansion and channel partner engagement is gaining traction,” said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. “In addition, we believe that our focus on strategic product development has opened the door to new markets, as demonstrated by the ‘M’ series, and we anticipate that our innovations in core process burners with 100% hydrogen capability will position us to serve a broader segment of the market and establish a strong foundation for future growth. We look forward to shipping a previously announced major order before year-end and continuing to expand our installation base and grow our sales pipeline.”
Strategic and Operational Highlights
Recent strategic and operational highlights including, and subsequent to, the third quarter of 2025:
Received Two Separate ClearSign Core(TM) “M” Series Burner Orders from Heater Manufacturer Devco Process Heaters: Both orders are for the new ClearSign Core™ M25. One of these orders is slated for installation in a hot oil heater at a New Mexico gas processing facility and the other will be installed as a retrofit in an existing hot oil heater at a gas processing facility of a multinational energy company in West Texas. The Company expects to deliver both burners in the first quarter of 2026.
Received Order for Fourth Low-Emission Flare Burner from Leading Energy Producer in California: The fourth burner order from a major energy producer in California covers engineering and design work for the retrofit of an enclosed flare at a production facility in California’s San Joaquin Valley, which is scheduled for installation in the second quarter of 2026. The scope of this order includes upgraded flare structure components and control systems, expanding ClearSign’s engagement beyond burner technology to include broader emissions and system integration solutions.
Received a 32-Burner Engineering Order from Global Supermajor: The Company received the initial computational fluid dynamic (“CFD”) analysis and engineering order from a supermajor refiner as the first phase of a process heater retrofit for a total of 32 ClearSign Core™ burners to be installed in one of its California refineries. The initial CFD analysis and engineering order was received directly from the customer for burners to be installed in two heaters in the supermajor refiner’s California facility. The Company expects the project to commence imminently and be rolled out in phases.
Received Order for Comprehensive Testing of 100% Hydrogen Capable Burner from Petrochemical Client Requesting Performance Mapping for Future Deployment: The Company received an order for a comprehensive range of process burner testing from a major petrochemical customer. The testing included the collection of comprehensive operational data over a range of operating conditions and fuel blends. The Company expects the testing to be completed, and its results to be delivered to the customer, in the fourth quarter of 2025.
Received Engineering Order for a 36 Process Burner Heater at a Texas Refinery: The Company received the initial engineering order from an integrated petroleum producer as the first phase of a process heater retrofit for a total of 36 ClearSign Core™ burners to be installed in their U.S. Gulf Coast refinery. The engineering order was received directly from the petroleum company. The proposed project is for installation in their U.S. Gulf Coast facility in Texas. The Company expects the project to be rolled out in phases.
