Biomethane processing has started at the biomethane refinery in Barsikow, Brandenburg: Sincemid October, the power generated by the micro gas turbines has been fed into the public powergrid. The first biomethane is expected to flow into the public natural gas grid from mid-December on. Every year, the plant will produce about 4.3 million standard cubic metres of biomethane.
This means about 1,000 standard cubic metres of biological raw gas an hour. About 375 standard cubic metres will be produced for the heat required for the plant, i.e. the needed process heat will be produced regeneratively. The heat will be provided by three micro gas turbines of 200 kWe each. From the remaining 850 cubic metres, 350 standard cubic metres of biomethane are produced and fed into the natural gas network. The total quantity corresponds to a thermal output of about 5MW. This annual amount of energy is sufficient to supply 3,000 four-person households with power or about 3,000 cars with an annual mileage of 30,000 miles. The reference project for Barsikow is the biogas refinery in Könnern, Saxony-Anhalt, whose annual biomethane production amounts to 15 million standard cubic metres. In the capacity of the general contractor, WELTEC BIOPOWER was responsible for the overall planning, turnkey set-up and installation, and commissioning of the plant in Barsikow.
