Introduction

Methane emissions detection is commoditized and crowded. Quantification, however, is difficult and expensive - until now. TrelliSense is on a mission to measure all anthropogenic GHG emissions from the ground, starting with methane and later expanding to other gases (e.g. CO2, N2O, ammonia). Our proprietary long-range, low-cost and continuous optical sensors detect, localize AND quantify methane emissions across entire sites using both dynamic and fixed optical sightlines using both fixed lasers and the sun as spectroscopic light sources. Primary applications include leak monitoring along the gas supply chain (upstream wells, midstream processing/distribution and utilities) as well as project MMRV and quantification at landfills, farms, coal mines and wastewater treatment plants.
