TrelliSense
ActiveWe measure. You cut. Emissions detection, localization, and quantification for sites of all shapes and sizes.
What it does
Methane detection, localization, and quantification over thousands of acres with the industry’s lowest-cost sensors. Our optical sensors continuously scan your assets like “methane radars” with zero disruptions to your operations, unlocking value through real-time and verifiable data. Our highly differentiated and proprietary sensor technology uses the sun as a spectroscopic light source to localize and quantify methane emissions from industrial infrastructure including oil and gas operations, landfills, coal mines, bio-digestion facilities and agricultural operations. Our sensors can also measure pollutants including HCN, HCl, NH3, O3, CO2, small hydrocarbons such as C2H2 and C2H4, and many others. TrelliSense is deployable at a fraction of the cost of today’s market solutions for continuous daily monitoring to cost-effectively monitor leaks, quantify site-level emissions, comply with methane regulations and capture value from emissions reductions.
