Gasum already holds majority ownership in the biogas upgrading company. The acquisition is part of Gasum’s strategic plan to invest in increased biogas production.

Nordic energy company Gasum has signed and closed a share purchase agreement for 100% of the shares in NSR Biogas AB and the remaining 1/3 of the shares in Liquidgas Biofuels Genesis AB. Gasum has already been the majority owner of Liquidgas Biofuels Genesis AB since 2023 and is now acquiring full ownership.

NSR Biogas AB owns and operates a biogas production plant in Southern Sweden’s city of Helsingborg. Liquidgas Biofuels Genesis AB upgrades the produced biogas at the site and Gasum sells it on to the market.

The plant uses approximately 160 000 tons of household and industrial waste as well as manure and the maximum production capacity is 80 gigawatt hours (GWh) of upgraded biogas per year.

“Since Gasum is already majority owner of the biogas upgrading operation, it makes sense for us to take ownership of the full production chain at the Helsingborg plant. Acquiring the operation strengthens our foothold in the Skåne region where competition for biogas feedstock is tough. There is also an opportunity to optimize operations at the plant to fully utilize its production capacity”, says Mika Wiljanen, CEO of Gasum.

One of the easiest ways to cut emissions

Gasum is investing heavily in increasing biogas production, especially in Sweden. The company is constructing new large scale biogas plants in the country, the first of which started production in early 2025. The second is under construction and is expected to start operations in 2026.

Replacing fossil fuels with biogas in maritime and land logistics as well as industrial processes, is one of the easiest ways to significantly cut emissions today. The lifecycle emissions of biogas are on average 90% lower compared to traditional fossil fuels such as diesel. When produced using manure, the emissions can even be negative.

Gasum’s strategic goal is to bring seven terawatt hours (7 TWh) of renewable gas to the Nordic market yearly by 2027. Achieving the ambitious goal would mean a total carbon dioxide reduction of 1.8 million tons per year for Gasum’s customers.
