Claye Souilly Wagabox: Pioneering Europe's Largest Landfill-to-RNG Project
At the Claye Souilly landfill near Paris, Waga Energy has established one of France's largest renewable natural gas (RNG) production units using its innovative Wagabox technology. Transitioning from a French feed-in tariff to a 13-year biomethane purchase agreement with Engie, this project underscores the viability of unsubsidized RNG production at scale. With an annual output of 120 GWh, the facility not only avoids 24,000 tonnes of CO2 emissions but also serves as a model for future landfill projects across Europe, supporting local green energy initiatives and enhancing energy security.
Theia Market Signal Identification - AI AssistedNestled near Paris, the Claye Souilly landfill has become the site of a groundbreaking renewable natural gas (RNG) production unit, operated by Waga Energy. Utilizing its proprietary Wagabox technology, the facility purifies landfill gas through a sophisticated process of membrane filtration and cryogenic distillation. This advanced method delivers biomethane of pipeline quality, boasting a remarkable purity of 98.6% methane.
Originally launched under the French feed-in tariff, the project has recently transitioned to a 13-year biomethane purchase agreement (BPA) with Engie, marking a significant milestone as the longest unsubsidized BPA in France’s history. This shift highlights the growing maturity of the landfill-to-RNG sector, demonstrating that long-term financing and market viability can exist without reliance on subsidies.
The Claye Souilly project is poised to produce an impressive 120 GWh of RNG annually, equating to approximately 409,500 MMBtu, while simultaneously preventing 24,000 tonnes of CO2 emissions each year. The biomethane generated is injected into the French distribution system operated by GRDF, ensuring that this green energy contributes to local consumption.
Veolia, a key partner in this venture, underscores its commitment to bioenergy by generating 1.6 terawatt-hours of biogas from waste in France. Through its strategic initiative, known as the Greenup plan, Veolia aims to expedite the adoption of low-carbon energy solutions, aligning perfectly with the objectives of the Claye Souilly project. This collaboration not only strengthens Engie's ambitious target of supplying 30 TWh of RNG by 2030 but also positions the Claye Souilly model as a replicable blueprint for large-capacity landfills across Europe.
The success of this project serves as a testament to the feasibility of unsubsidized RNG production at scale, paving the way for a more sustainable energy future and reducing reliance on fossil fuel imports. As the green gas industry continues to evolve, the Claye Souilly landfill stands as a beacon of innovation in the transition toward a low-carbon economy.
