Plant profile: Güstrow

Location: 18273 Güstrow, Germany

In-service date: expected mid 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:

From its planned pilot operation in the second quarter of 2023, the Güstrow plant will aim to supply significant quantities of purified bio-LNG to help make heavy goods traffic greener. 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
  • From mid-2023 onwards, EnviTec aims to facilitate the annual production of around 9,000 tonnes of bio-LNG (liquefied natural gas)
  • To date, the 500 GWh biogas upgrading unit fed into the 25 bar natural gas grid. The previous owners also ran the plant on around 400,000 t of substrate, which was predominantly sweet corn, but also included whole-plant silage, cereals and grass silage.
  • In the new business operating model, input will now be reduced to 150,000 t per annum, agricultural residues will be primarily utilised and additional CHP units will be ‘docked on’ to supply 2.14 MWel of on-site power to the facility. Digestate storage capacities have also been adjusted to match.
  • Conversion work on the Güstrow site required investment in a CO2 liquefaction plant and an LNG system for biomethane liquefaction, as well as extensive capital spending on replacements such as new roofs and agitators amounting to EUR 45–50 million.
