ClearSign Technologies Corporation focuses on innovating and developing advanced solutions to elevate operational efficiency, reduce environmental impact, and improve the cost-effectiveness of industrial and commercial systems across North America, Europe, Asia, and the Middle East. The company's technology suite aims at decarbonization and enhancing key performance characteristics, particularly by enabling lower emissions and safer operations. Central to their offerings is the ClearSign Core™ burner technology, featuring patented ceramic or metal flame stabilization for industrial applications. This includes ClearSign Core™ Process Burners, designed as direct replacements for refinery heaters, and the recently introduced "M" Series tailored for midstream gas facilities, now with capabilities for 100% hydrogen fuel. Additionally, the portfolio extends to ClearSign Core™ Boiler Burners for improved boiler performance and ClearSign Core™ Flaring Burners that significantly reduce nitrogen oxide emissions. Complementing these are the ClearSign Eye™ flame sensors, providing crucial electrical flame detection for various industrial environments. The company actively partners with equipment manufacturers to embed its technologies, adopting an asset-light model to broaden market reach and service capabilities, and generates revenue through product sales, licensing, and engineering services. Recent initiatives include the commercial launch of co-branded Zeeco CS5 and Zeeco Hydrogen CS5 Burners in partnership with Zeeco, along with the first commercial deployments of the ClearSign Eye™ sensor at major refineries. ClearSign also recently secured multiple orders for its "M" Series burners and low-emission flare retrofits, and has undertaken comprehensive testing for 100% hydrogen-capable burners, indicating a strategic expansion into cleaner fuel solutions. Established in 2008, the entity was initially known as ClearSign Combustion Corporation before officially rebranding to ClearSign Technologies Corporation in November 2019 to reflect its broader technology focus. The company maintains its primary operational base in Tulsa, Oklahoma, with an additional office in Seattle, Washington.
