The rise of Evergaz in France
After announcing in November 2021 the acquisition of the German group C4 and the management of 10 new biogas plants in Germany, Evergaz is continuing its development in France with the operational start-up of Dual Prémery, an anaerobic digestion unit located in the Bourgogne-Franche-Comté region. , which injected its first cubic meters of biomethane into the GRDF network on April 1, 2022. Evergaz is a 30% shareholder in the site, in partnership with Meridiam, alongside the DualMetha* group, the project’s historical shareholder. Through this territorial methanation project, Evergaz reaffirms its desire to develop in France and strengthen its territorial network, while diversifying its portfolio technologically.
A biogas plant equipped with innovative technology
The Prémery methanation unit is particularly technologically innovative: the technology used, called DualMetha, is a so-called “submerged” methanization combining discontinuous dry process methanation with the continuous liquid process in order to be able to treat all types of materials without any preparation. It is thus a pioneer in the creation of a new generation of methanizers, with the aim of producing competitive biomethane thanks to better energy efficiency. DualMetha is a French process, winner of an ADEME Future Investment Program.
Positive externalities for the territory
The Dual Prémery site is a concrete example of the contribution of the territories to the national objectives of ecological transition and energy independence. With a capacity of 150 Nm3/h, the biomethane injection site can supply 2,400 people with green gas. A perfect illustration of the local circular economy, the site also recovers waste heat from the neighboring company PremEster, which specializes in waste and fat management, to heat its digesters.
Dual Prémery offers a competitive solution for the recovery of organic waste from the territory, and produces a natural fertilizer with recognized agronomic virtues and substitutable for chemical fertilizers, called digestate. The site will eventually prevent the emission of the equivalent of more than 3,000 tonnes of CO2 per year.
“We are delighted with the start of operation of the Prémery methanisation unit, which constitutes a step forward in the development of biogas in the Bourgogne Franche-Comté region. This partnership once again confirms our desire to participate in the energy transition by producing renewable, local and flexible energy, a real substitute for imported fossil fuels.”declares Alain Planchot, Chairman and CEO of Evergaz.
*The other shareholders of the Dual Prémery methanisation unit are: SEM Nièvre Énergie, Enagas Emprende SLU, SBM Développement and Engie Bioz.
