Insights

Cleantech Investment Analyst

ClearSign shows strong business execution with new product launches, major customer wins, and strategic partnership expansion in clean combustion technology.

ClearSign Technologies is making meaningful commercial progress in Q1 2025 across multiple fronts. The company has expanded its product portfolio with two significant launches: the co-branded Zeeco CS5 and Zeeco Hydrogen CS5 Burners through its partnership with combustion leader Zeeco, and the new M Series burners targeting the midstream market. These product introductions are strategically important as they diversify revenue streams while addressing increasingly stringent emissions regulations.

The company's commercial traction is accelerating, evidenced by their installation commitment at a supermajor refinery for the ClearSign Eye Sensor technology. This represents a crucial validation from a top-tier customer. Additionally, they've secured repeat flare burner orders from an energy company in California, indicating product satisfaction and potential recurring revenue.

What's particularly promising is the multiple market segments ClearSign is penetrating: refineries (supermajor installation), chemical processing (Gulf Coast facility), oil and gas production (flaring solutions), and midstream (M Series, Colorado installation). This diversification reduces reliance on any single market.

Financially, ClearSign maintains a cash position of $12.8 million as of March 31, 2025, providing operational runway. With 52,422,532 outstanding shares, the company has flexibility for future capital needs while pursuing commercialization.

The key value proposition centers on ClearSign's ability to achieve ultra-low NOx emissions (sub 5 ppm) while supporting the energy transition through 100% hydrogen compatibility. As emissions regulations tighten globally and hydrogen adoption increases, ClearSign's technology addresses critical industrial decarbonization challenges while improving operational efficiency - positioning them well in the evolving clean energy landscape.

TULSA, Okla., May 21, 2025 /PRNewswire/ -- ClearSign Technologies Corporation (Nasdaq: CLIR) ("ClearSign" or the "Company"), an emerging leader in industrial combustion and sensing technologies that support decarbonization, improve operational and energy efficiency, enable the use of hydrogen as a fuel and enhance safety while dramatically reducing emissions, today provides an update on operations for the quarter ended March 31, 2025.

"We had a productive first quarter of the year, which included expanding both our sales channels and our product offerings," said Jim Deller, Ph.D., Chief Executive Officer of ClearSign. "In March, we launched co-branded process burner lines named Zeeco CS5 and Zeeco Hydrogen CS5 Burners with our partner, Zeeco. We also introduced our new M Series burners for the midstream market and secured repeat orders and sales opportunities with heater manufacturers.  Additionally, we received commitments for the first commercial installation of our 'ClearSign Eye' Sensor at a supermajor refinery and we are seeing renewed interest in our flaring solutions to meet emissions requirements for prominent oil and gas production customers."   

Strategic and Operational Highlights

Recent strategic and operational highlights during, and subsequent to, the first quarter of 2025 include:

Received Engineering Order for a Low Emissions Flare Burner for Energy Company in California: The Company announced that it had received an engineering order for an additional retrofit burner for a flare from an energy company for use in California. This is the second burner sold to this customer within the year, and the third overall. The Company is seeing an increased interest in this product line.

Launched New ClearSign Core™ M Series Process Burner Technology and Announced installation into Texas and Sale into Colorado: The Company debuted a new burner technology with the installation into a U.S. Gulf Coast facility of a global chemical company.  The sale came through the Company's channel partner, Tulsa Midstream Heater. The testing of the M Series process burner subsequent to its installation showed selective catalytic reduction ("SCR") level nitrogen oxide ("NOx") emissions in addition to improved heat transfer efficiency within the heater. 

Weeks later, the Company announced that it received a purchase order for another M series process burner, the ClearSign Core™ M1, from heater manufacturer, Devco Process Heaters of Tulsa, Oklahoma, to be installed in a gas processing facility in Colorado. 

Announced Launch of Co-Branded ClearSign Core Process Burner Product Line with Zeeco, Inc. ("Zeeco"): The Company expanded its collaborative working relationship with Zeeco, a world leader in advanced combustion solutions, to launch co-branded process burner lines named Zeeco CS5 and Zeeco Hydrogen CS5 Burners. This new line of burners, which features ClearSign Core technology, can fire 100% natural gas and 100% hydrogen while maintaining sub 5 ppm NOx to comply with strict emission regulations. Both companies are collaborating on global sales and marketing of these new burner lines.

ClearSign Technologies Corporation to Install ClearSign Eye Sensors at Supermajor U.S. Gulf Coast Refinery: The Company is installing four "ClearSign Eye" sensors on each burner of a multi-burner process heater in a supermajor refinery located on the U.S. Gulf Coast, which are expected to be installed in the second quarter of this year.
