The primary aim of the whitepaper is to present eLichens' advancements in methane (ch4) leak detection and monitoring technology, focusing on outdoor testing of our sensor, designed to identify and monitor leaks in real-time in open-field conditions. It outlines the experimental approach for testing first a 10 ppm methane sensor prototype, highlighting its significance for industries looking to monitor and control methane emissions more effectively. This study takes place in the scope of the project fuitographie that eLichens conducts with its partners CEA-Leti and GRDF. Download below the study.
