ClearSign Technologies operates in the oil and gas sector, developing technologies designed to address capital-intensive emissions-control requirements that can reduce throughput, consume energy, complicate design, and erode profits. The company offers retrofit solutions intended to deliver stronger emissions control and improved combustion performance at a fraction of the cost of traditional after-treatment methods. These methods can be applied wherever there is an open flame, regardless of fuel type.

Based in Tulsa, Oklahoma, the company is a small to mid-sized entrant in the energy technology space and trades on NASDAQ under CLIR. In early 2026, it announced a new client relationship with Tulsa Heaters Midstream and an order for its M1 burner.
