St1, together with St1 Biokraft, successfully delivered liquefied biogas (LBG) to a Terntank vessel at the Port of Gothenburg for the first time in 2025.

The delivery showcased the companies’ ability to supply self-produced biogas to the maritime sector at one of the most strategic ports in the Nordics, marking a significant step for St1’s marine business and energy transition journey.

In collaboration with Nordion Energi and the Port of Gothenburg, St1 and St1 Biokraft laid the foundation for a complete biogas value chain from production to bunkering. Nordion Energi’s liquefaction plant, scheduled for completion in 2027, will play a key role in reinforcing the port’s biogas infrastructure.

“By establishing a complete supply chain in collaboration with key partners, we have positioned ourselves well to efficiently offer LBG to the shipping industry. This is a necessary step that complements our product portfolio for the marine segment, strengthening our position as a marine fuel supplier in the Nordics,” says Mattias Ivarsson, Marine Business Development Manager at St1.

The combination of Nordion’s bunkering facilities and the liquefaction plant creates new business opportunities for St1 and St1 Biokraft.

“Once the liquefaction plant is operational, we will have a robust solution in place in the Port of Gothenburg. It is a strategic step towards our goal of scaling up and providing competitive liquefied biogas to the maritime sector, and thereby taking a leading position in the Nordic region,” adds Ted Gustavsson, Head of Value Chain at St1 Biokraft.

LBG plays an integral role in hard-to-abate sectors such as shipping. From 2027 onwards, St1 and St1 Biokraft will be able to provide a comprehensive bunkering solution for liquefied biogas in Sweden, enabling shipping companies to accelerate their long-term transition from fossil fuels to low-emissions alternatives.
