Nordion Energi Awards Wärtsilä Contract for Construction of Liquefied Biogas Facility

The industrial group Wärtsilä has been appointed to build Nordion Energi’s biogas liquefaction plant in the Port of Gothenburg. The facility is part of Nordion Energi’s plan to transition the gas network to 100% biogas. It will enable biogas producers connected to the gas grid to reach new customers such as the shipping industry, heavy transport, and off-grid industrial users.

- The liquefaction plant in Gothenburg is an important step in making the gas network more attractive to biogas producers and has already sparked increased interest in connecting to the grid. A greater number of domestic biogas producers will both reduce the environmental impact of gas and enhance security of supply, says Carolina Wistén, Director Customer and Market at Nordion Energi.

Biogas is a renewable fuel with low climate impact that can replace natural gas in various processes. Of the gas delivered through the western Sweden gas network, 39.3 percent consisted of biogas in the first quarter of 2025. The goal is for all gas delivered through the network to be biogas by 2030. The planned facility in the Port of Gothenburg is intended exclusively for biogas and will enable the gas to be liquefied and then delivered to new customers.

- This plant will produce 50 tons of bioLNG per day and will, by sharing the existing infrastructure with natural gas, offer a safe, cost efficient, and fast path towards decarbonisation. Our technologies are well proven to deliver high uptime with reliable and safe performance, and we are extremely pleased to be working with Nordion Energi on this important project,” commented Rolf Håkansson, Sales Manager, Wärtsilä Gas Solutions, Biogas.

The liquefaction plant is scheduled for delivery in September 2026, with the goal of being operational before the end of 2026.
