TRIG is developing low-power, small (localized) methane sensors for detecting larger emissions at the source (e.g., wellhead, pressure release valve, storage tank vent line). When these sensors are properly rated for safety and site access, TRIG will propose different mounting positions that will allow the detection of a significant process or equipment failure. Within the scope of the ETC, TRIG …
Satellite Detection of Controlled Releases
GHGSat launched its first methane detection satellite in 2016 and now has 12 satellites in orbit, including its first carbon dioxide detection satellite, launched in November 2023. Each satellite uses patented infrared detection technology. Detection thresholds have improved 10-fold since 2016 and are currently reported as being ~ 4,000 m3/day or 100 kg CH4/hr.
Field trial of a drone combined with a Tunable Diode Laser Absorption Spectroscopy (TDLAS) methane detector, to detect and locate methane release source points.
AltoMaxx drone expertise has been combined with a Tunable Diode Laser Absorption Spectroscopy (TDLAS) methane detector. The Lower Detection Limits (LDL) is 5 ppm-m. This allows users to fly over a site and determine the exact location of methane releases. AltoMaxx is developing capabilities to quantify methane releases with drone surveys using both TDLAS and OGI technologies.
