Abstract

This eight-year study characterized trace compounds in grid-injected biomethane from methanization using a multi-analytical strategy combining broad thermal desorption gas chromatography-mass spectrometry (TD-GC/MS) screening with targeted quantitative methods. Between 2016 and 2023, 75 sampling campaigns were conducted at 40 French biomethane injection plants, covering diverse feedstocks and upgr…
