Greenline’s expanded 8.5 MW biogas plant now in operation

A biogas plant in Vettin, developed by Greenline GmbH and located in the municipality of Groß Pankow, is now in regular operation using input materials such as slurry, solid manure, and maize silage.
Greenline’s expanded 8.5 MW biogas plant now in operation

The 8.5 megawatt biogas plant was developed by the planning office of Greenline, situated in Flensburg and is operated by the biogas division of technical contractors Osters & Voss from Wittenberge in the district of Prignitz. The plant builds on the existing 800 kW biogas site which began operating in 2014. It has now been expanded and focuses predominantly on a mix of cattle slurry and energy crops. The raw biogas is converted into bio-natural gas using physio-organic washing processes and then fed into the regional natural gas network of the Brandenburg utility company, E.ON-E.DIS.

The expanded plant processes approximately 70,000 tonnes of slurry, 50,000 tonnes of maize silage, and 7,000 tonnes of solid manure, generating around 75 million kilowatt-hours of gas and heat. This represents enough heat and electricity to supply approximately 16,000 households.

The plant incorporates three fermenters and two secondary fermenters with a fermenting volume of around 23,000 cubic metres in total. There are six digestate storage tanks with a holding capacity of around 42,000 cubic metres and a pump line measuring approx. two kilometres in length which ensures the efficient and ecological transportation of substrates. The slurry is delivered by a dairy farm directly to the biogas plant.

“The biogas plant ranks among the largest in Germany in tank volume and gas production, setting functional and operational benchmarks” said Greenline Managing Director, Frank Nielsen. “High quality, low production and operational costs, and a high degree of automation in new construction and flexibilisation projects are all helping to establish biogas production as the standard energy alternative in the market of regenerative energy sources going forward. In particular, thanks to the latest EEG amendment and the modified framework conditions for approval, efficient planning concepts and low building costs are fundamental to the chances of executing biogas projects. Furthermore, waste plants for foreign markets with CO2 certificates are becoming increasingly more important. Here too, competitive kWh generation throughout the operational period plays a decisive role.”
