About ClearSign Technologies
From its filings with the US Securities and Exchange Commission
ClearSign Technologies is based in Tulsa, Oklahoma and is incorporated in Delaware. Its shares trade on Nasdaq under the ticker CLIR. The SEC classifies its business as industrial instruments for measurement, display, and control. In the fiscal year to 31 December 2025, it reported revenue of $5.2m and a net loss of $5.5m. At that date it held total assets of $12.2m and shareholders' equity of $9.5m.
We design and develop technologies for the purpose of decarbonization and improving key performance characteristics of industrial and commercial combustion systems, including emission and operational performance, energy efficiency, and overall cost-effectiveness. We believe that our patented ClearSign Core™ technology can enhance the performance of combustion systems in a broad range of markets, including the energy (upstream oil production, midstream gas processing and transportation, and down-stream refining), institutional, commercial and industrial boiler, chemical, and petrochemical industries. Our ClearSign CoreTM technology, which is our primary technology, uses either a porous ceramic structure or metal flame holder device held at a distance from the injection planes of a burner to significantly reduce flame length and achieve low emissions without the need for external flue gas recirculation, selective catalytic reduction, or high excess air systems. To date, our operations have been funded primarily through sales of our equity securities.
Our combustion technology has been successfully deployed in commercial projects such as down-stream refining and upstream oil production. These applications include our process burner, flaring and boiler burner technologies. Both our process burner and boiler burner technology can operate in high-intensity industrial burner applications at sites that are required to meet low air pollutant emissions.

SWOT analysis
AI-generated by our data supplier. Not written or checked by our editors.
Strengths
- Clearsign Technologies Corp has developed innovative and patented technologies in the combustion industry, providing them with a unique competitive advantage. Their advanced combustion systems offer improved energy efficiency, reduced emissions, and increased operational flexibility.
- The company has a strong intellectual property portfolio, which includes key patents and proprietary designs. This strengthens their position in the market and offers potential licensing opportunities to generate additional revenue.
Weaknesses
- Clearsign Technologies Corp currently operates in a highly competitive market with well-established players. As a relatively smaller company, they may face challenges in penetrating and gaining market share.
- Their technologies require significant customer education and adoption efforts. The transition from traditional combustion systems to Clearsign's innovative solutions may be met with resistance and skepticism from potential customers.
Opportunities
- Increasing global environmental regulations and growing concerns over carbon emissions create a favorable market environment for Clearsign Technologies Corp. Their environmentally friendly solutions can help companies comply with stricter regulations and reduce their carbon footprint.
