Key facts

In regular operation, the Güstrow plant will supply about 9,600 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. Numerous agreements have already been signed with customers looking to offer this LNG as an alternative fuel at their filling stations.

• 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 9,600 metric tonnes of bio-LNG (liquefied natural gas) and 15,000 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 MW_el 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.
