Schmack Biogas, part of the Viessmann Group, has been awarded a contract to construct a biomethane plant in Sourdun in northern France. This follows the French government’s adoption of a feed-in tariff for biogas in December of 2016.
It is hoped that the new biogas plant, being built for local company SARL Létang Biométhane, will produce 250 normal cubic metres per hour (Nm3/h) of raw biogas in the first phase of development, potentially increasing to 500 Nm3/h in the second phase.
The raw biogas will be refined to a methane content of at least 97% by means of pressure swing adsorption (PSA process). As a result, the biogas will be natural gas quality allowing it to be fed into Sourdun's local supply network.
