Plant Profile: BioEnergiepark Güstrow
Location: 18273 Güstrow, Germany
Capacity: around 9,000 t Bio-LNG and around 18,000 t LCO2 p.a., CHPs with 3.1 MWel
In-service date: 2009, conversion in 2023
Input materials: 150,000 tonnes p.a., mainly agricultural waste materials
Special features: Germany's largest integrated bio-LNG plant (bio-LNG incl. CO2 liquefaction plant)
Key facts
The Güstrow plant supplies about 9,000 t of bio-LNG per year to help make heavy goods traffic greener. In terms of mileage, this output of green fuel can power 50 million truck kilometres a year.
- Commissioning of Germany’s largest biogas plant, built by EnviTec Biogas, in 2009
- Purchase and transfer to EnviTec Own Investment in 2021
- Production of about 9,000 metric tonnes of bio-LNG (liquefied natural gas) and around 18,000 metric tonnes of bio-LCO2 in regular operation
- Previously, the 500-GWh biogas upgrading unit fed biomethane into the 25-bar natural gas network. The former operator required around 400,000 metric tonnes of substrate for this. This was predominantly sweet corn, but also included whole plant silage, cereals and grass silage.
- The new operating concept, input will be reduced to 150,000 metric tonnes per annum, primarily consisting of agricultural residues. Additional CHP units will be 'docked on' to supply 3.1 MWel of power for the plant's own use. Digestate storage capacities have also been adjusted accordingly.
- The conversion of the Güstrow site required investment in a CO2 liquefaction plant and an LNG plant for biomethane liquefaction as well as extensive reinvestment in elements such as new roofs and agitators amounting to more than EUR 50 million.
