Biomethane units connected to the gas network in France

This map identifies all the biomethane units connected to the gas network in France in August 2022.

In August 2022, 457 units were injecting biomethane into the French gas network.

Projects are mostly connected to the distribution grid (88%), but also increasingly to the transport grid (the choice between both is made according to the Injection law of November 2019). Most facilities are agricultural (84% of injection units), followed by water treatment plants (7%), industrial facilities (3%) and non-hazardous waste landfill (3%).


Even though facilities can have a considerable capacity (122 GWh/year for the biggest one, in Seine-et-Marne), half of facilities have a capacity inferior to 14 GWh/year (indeed, agricultural sites and water treatment plants tend to have small capacities). Grand-Est and Hauts-de-France are the territories with the highest production capacities, being respectively 1646 and 1447 GWh/year.

Between January and September this year, 92 new biomethane injection units were set, which represents an increase of 55% of the total number of injection units compared to mid-2021. Some territories are particularly dynamic : Nouvelle-Aquitaine (with a rise of 86% compared to mid-2021), Auvergne-Rhône-Alpes (80%) and Ile-de-France (79%).
