ClearSign Technologies Corp

CLIR·NASDAQ·Industrial Applications And Services·CIK 0001434524

ClearSign Technologies Corporation designs and develops technologies for decarbonization and improving industrial and commercial combustion systems. The company focuses on enhancing emission and operational performance, energy efficiency, and cost-effectiveness. Its primary technology, ClearSign Core™, uses a porous ceramic structure or metal flame holder to reduce flame length and achieve low emissions without external flue gas recirculation, selective catalytic reduction, or high excess air systems. ClearSign Core™ technology is applicable across various markets, including energy (upstream oil production, midstream gas processing and transportation, downstream refining), institutional, commercial, industrial boiler, chemical, and petrochemical industries. The company's combustion technology has been deployed in commercial projects within downstream refining and upstream oil production, encompassing process burner, flaring, and boiler burner technologies. Both process burner and boiler burner technologies operate in high-intensity industrial burner applications, meeting low air pollutant emission requirements. ClearSign believes its technology is more effective and cost-efficient than current industry-standard air pollution control technologies, capable of reducing nitrogen oxide ("NOx") emissions to levels required by stringent regulations. NOx is a regulated greenhouse gas pollutant. Current industry-standard technologies include selective catalytic reduction devices ("SCRs"), low- and ultra-low NOx burners, and external flue gas recirculation systems, commonly used in petroleum refining and petrochemical process heaters, large-scale once through steam generators ("OTSGs"), enclosed flares, and institutional commercial and industrial boilers. Operations have been funded primarily through equity security sales.
