Initiating Coverage: ClearSign Technologies (NASDAQ: $CLIR) — Advanced Combustion Technology Addressing a Growing NOx Compliance Market • ClearSign’s proprietary ClearSign Core™ technology is designed to reduce NOx emissions at the source, offering refiners, petrochemical facilities, and gas processors an alternative to traditional post-combustion treatment systems • The company’s opportunity is driven primarily by tightening air quality regulations, with California and the Texas Gulf Coast representing significant retrofit markets and additional potential across global industrial regions • ClearSign’s asset-light model is supported by strategic partnerships, while management continues targeting key commercial milestones including flare testing, project startups, and conversion of engineering orders into equipment shipments Read Peter Gastreich's initiation of coverage for more detail on ClearSign’s technology, market opportunity, commercial strategy, and long-term growth outlook. watertowerresearch.com/doc?docID=IOC_… $CLIR #IndustrialTechnology #CleanTech #EnergyTransition #EmissionsReduction #EnvironmentalTechnology #NASDAQ #Investing #WaterTowerResearch @ClearSign
We’re excited to announce the next phase of a major California refinery retrofit project featuring a total of 32 ClearSign Core™ burners. 🔥 Following successful engineering and CFD simulations, we’ve now received a purchase order to move into full-scale burner testing and demonstration at Zeeco’s Global Technology Center. This project will feature another configuration of our Core 2 technology, further expanding the applications for our ultra-low NOx burner platform across the refining industry. 🌐Read the full press release here: clearsign.com/clearsign-rece…
Is your low NOx enclosed flare limiting capacity? ClearSign has retrofitted other low NOx flares with our technology to provide reliable low emissions flaring when the previous flare burner struggled to meet emissions. In some operations, flare emissions can directly limit your total production. If you are leaving production capacity on the table because of your flare, reach out to see how a ClearSign flare can help: clearsign.com/contact 🌐
ClearSign Technologies’s latest update highlights continued commercialization progress driven by tightening NOx regulations and growing customer adoption. 🔹 Proprietary burner technology prevents NOx formation, offering a cost-advantaged solution amid tightening global regulations. 🔹 Record 4Q25 revenue ($3.7M) and strong backlog (~225 burners) reflect increasing demand from major refiners. 🔹 Key near-term catalysts - upcoming installations, demonstration events, and order conversions remain important milestones. 🔹 Don't miss CLIR at The WTR Insights Conference on Wednesday, April 15th at 3:10pm ET.

ICYMI: Our CTO, Matthew Martin recently presented at the ABMA Boiler Expo. Through real-world case studies, Matt highlighted how CFD modeling can be used to predict burner–furnace interactions and estimate NOx emissions in advance. This process enables more informed design decisions, improved performance, and reduced risk during project implementation. Want to learn more?

#Didyouknow we have a 3D model of our ClearSign Core™ M1 burner? Our most advanced ultra-low NOx solution to date, designed for midstream and power applications, the M1 achieves 2ppm NOx at just 3% excess O₂ without relying on metal mesh, ceramics, or external sensors. Want to see it in person? Visit us at an upcoming show: ➡️ ABMA Boiler – Nashville, TN | Mar 31-Apr 2 ➡️ Texas Environmental Trade Fair & Conference – San Antonio, TX | May 19-20
We’re proud to share that the development phase of our SBIR funded 5ppm flexible fuel burner development project with the @ENERGY @NETL_DOE is complete and has been recognized as a meaningful step forward in industrial combustion. Through this $1.65M program, we’ve significantly advanced our Flexible Fuel Ultra-Low NOx Process Burner. This was designed to allow industrial facilities the ability to seamlessly switch between natural gas and fuel blends common in refining and petrochemical plants, and up to and including 100% hydrogen. The burners enable flexible fuel use, improving operational efficiency and adaptability while maintaining sub-5 ppm NOx compliance. We’re grateful for the DOE SBIR program, and NETL for supporting this project, and technology innovation programs such as this.
