Sweden's Nordion Energi Completes Installation of 500 m³ Liquefied Biogas Tank at Port of Gothenburg

en.Wedoany.com Reported - On November 12, Swedish energy infrastructure company Nordion Energi completed the installation of the core storage tank at its liquefied biogas (LBG) plant at the Port of Gothenburg. The tank has a capacity of 500 m³ and weighs approximately 140 tonnes, and will be able to store up to 200 tonnes of liquefied biogas once operational. The plant is scheduled for completion in the second quarter of 2027, at which point its annual supply capacity will reach 250 million kWh (250 GWh), with fuel primarily targeting vessels, heavy-duty transport vehicles and industrial users.

Prior to the tank installation, the project had completed the foundation, base slab and related civil works; this installation marks the plant's first major equipment component. The project is invested in, built and owned by Nordion Energi, and is designed with a direct connection to the natural gas grid in western Sweden, making it Sweden's first biogas liquefaction plant directly connected to that grid. Once connected, biogas producers from different regions can feed gas into the plant, where it undergoes purification and liquefaction before entering the storage tank, and is then supplied to end users via tanker truck transport or port-area bunkering facilities.

The project's main operational stages include grid transmission, gas liquefaction, cryogenic storage and fuel delivery. Compared with building small-scale liquefaction facilities in a decentralized manner, centralized connection to the natural gas grid allows biogas resources from different regions to be pooled, reducing geographical constraints between production sites and fuel consumption locations. Once operational, the plant's annual supply is expected to meet the annual fuel demand of approximately 500 heavy-duty trucks, or provide bunkering fuel for approximately 50 vessels.

Downstream supply agreements are already being implemented. Swedish biogas company ST1 Biokraft has previously signed an agreement securing part of the plant's liquefied capacity; the Port of Gothenburg also currently has shipping companies that call regularly and use liquefied biogas as marine fuel. Once the new facility is completed, the port will gain centralized supply and vessel bunkering capacity for liquefied biogas, while also serving industrial users and heavy transport companies that lack direct access to the natural gas grid.
