The conversion and assembly work at Germany’s largest integrated bio-LNG plant with bio-CO2 liquefaction, BioEnergie Park Güstrow in Mecklenburg-Western Pomerania, has just been completed.
The EnviTec Biogas team is now ready to start placing the plant into operation.
Frank Hinken, MD of EnviTec Bioenergie Güstrow says: ‘Now that the last component, the 300,000-litre LCO2 tank made of pressure vessel steel, has been integrated, we can start the test phase with the newly installed plant components…The bio-CO2 produced can be used in food and beverage production sectors or, in greenhouses.’
The off-gas created during the liquefaction of CO2, which contains other non-condensable gases such as nitrogen, oxygen and hydrogen as well as methane, is fed to the combined heat and power plants at the site, where it is used to generate energy for self-supply.
‘Through this active circular economy, we are making an important contribution to a greener transport sector,’ adds Jürgen Tenbrink, CTO of EnviTec Biogas AG.
Once in operation, the plant will produce 25,000 kg of bio-LNG daily for heavy-duty transport vehicles. This will provide green fuel for more than 50,000,000 lorry km per year.
At the same time, the liquefaction of biomethane is accompanied with the liquefaction of carbon dioxide via the gas treatment process. The liquid carbon dioxide, 15,000 metric tonnes per year generated at food quality, substitutes fossil-based carbon dioxide.
