- ClearSign Technologies Corporation (NasdaqCM: CLIR) develops and commercializes proprietary technologies for the purpose of improving the efficiency and emissions profile of industrial and commercial combustion systems, including burners, flares, and thermal oxidizers. The company's core products and services encompass ClearSign Core Burner (CSB) technology, which integrates ClearSign's patented Selective Catalytic Reduction (SCR) and Controlled Flame Development (CFD) mechanisms to achieve ultra-low NOx emissions without the need for external flue gas recirculation or ammonia injection; Duplex Platform burners for applications in boilers, furnaces, heaters, and process operations; and flare systems such as the ClearSign Core Flare (CCF) and Elective Catalytic Flare (ECF), designed to minimize methane slip, smoke, and NOx while enhancing destruction efficiency for waste gas streams in oil and gas facilities. Additional offerings include process heaters, thermal oxidizers, and retrofit solutions for existing combustion equipment across refining, petrochemical, power, and renewables sectors, targeting industrial customers seeking regulatory compliance and operational cost reductions. Founded in 2008 and headquartered in Tulsa, Oklahoma, ClearSign operates primarily in North America with expanding presence in international markets including the Middle East and Asia. In recent developments, the company announced a strategic partnership with a leading U.S. refiner in 2024 for commercial deployment of its CSB-CFX steam generation technology, secured a multi-unit order for ECF flares from a natural gas midstream operator in early 2025, and expanded its product portfolio through the launch of next-generation CFD-enabled burners optimized for hydrogen-blended fuels amid the energy transition.
