This project is run by the SAS Agribiométhane consortium of ten farmers from four different farms. It has also received support from many other stakeholders, including ADEME (the French Environment and Energy Management Agency) and the Vendée General Council.
This unit will be the first of its kind in Western France and only the fourth in the country. It will process 21,000 metric tons of substrates representing more than 70% of the livestock effluent generated by the four farms, as well as 6,000 metric tons of food industry organic waste collected and supplied by SUEZ ENVIRONNEMENT.
Green gas is the generic term applied to all gases produced from a renewable source. Biogas is a green gas released naturally when organic matter decomposes in an oxygen-free environment. After purification, this biogas becomes biomethane, and is odorized, checked and metered by GrDF before injection into natural gas supply systems.
Production is expected to reach 1 million m³ of raw biogas per year. 80% of the remaining product (digestate) will be spread on agricultural land as a fertilizer and conditioner. The first gas was injected into the mains system in April this year.
At the start of this year, the European Commission set the target of a 27% contribution from renewable energy sources by 2030, with a parallel reduction of 40% in greenhouse gas emissions. The same ambition is shared in France as part of the national energy transition and the many regional plans launched to promote the use of clean, safe energy generated close to the point of consumption.
GDF SUEZ has set itself the target of making a 5% biomethane contribution - equivalent to 20 TWh - to mains gas supplies by 2020. Since 2010, its GrDF subsidiary has provided joint management of the injection working group alongside ADEME, makes an active contribution to developing this green energy source, and estimates that 73% of all the gas in the network will be green gas by 2050.
GDF SUEZ and its partner SUEZ ENVIRONNEMENT are particularly involved in developing this energy of the future, which offers many benefits:
