Biogas
What is biogas?
Biogas is produced from the decomposition of organic material. In practice, biogas is generated by collecting household waste, such as wastewater and food scraps, along with manure from farms, and breaking them down in an anaerobic environment. The resulting gas is then upgraded into either compressed biogas (CBG) or liquefied biogas (LBG), while the remaining mass is processed into biofertilizer for fields. These biofertilizers support food production, completing a sustainable carbon cycle.
Biogas significantly reduces emissions in heavy traffic
Biogas plays a significant role in the energy transition and the reduction of emissions from transport. Biogas accelerates the shift from fossil fuels to renewable solutions, particularly in heavy-duty transport. By transitioning to biogas-powered vehicles, companies can substantially reduce emissions in their logistics chains.
Depending on its origin, the use of biogas in heavy transport can reduce emissions more than 100 percent. In terms of performance, biogas is equivalent to conventional diesel.
St1 is aiming for an extensive biogas distribution network
St1 is expanding its distribution network of liquefied biogas (LBG), with the goal of establishing a network of over 50 LBG refueling stations across Finland, Sweden and Norway by the end of 2028.
In Finland, St1 expanded its station network in 2024 by opening LBG refueling points at Shell Hämeenlinna Iittala, St1 Mäntsälä P, and Shell Salo Halikko. In 2025, the goal is to introduce LBG refueling points at Äänekoski Hirvaskangas, Vantaa Voutila, Iisalmi, and Liminka Tupos, with plans to further expand the refueling network nationwide.
In Sweden, St1 already has an extensive compressed biogas (CBG) refueling network, covering approximately 60 stations. Additionally, the first liquefied biogas station has been opened in Torsvik, Jönköping. In Norway, St1 aims to open its first three LBG refueling points in 2025, provided that the permitting processes proceed as planned.
The biogas sold at St1 and Shell stations will initially come from the Swedish production plants of St1 Biokraft, which is a joint venture of St1.
When the new production plants of Suomen Lantakaasu Oy, owned by St1 Biokraft and Valio, are completed in 2026, Finnish biogas will also be available for distribution.
St1 Biokraft – Towards becoming the leading biogas operator in the Nordics
St1 Biokraft AB is a joint venture between St1, HitecVision and Aneo. St1 Biokraft consists of former St1’s biogas assets and Biokraft International AB. St1 Biokraft integrated the two entities into one company in 2024 with the ambition of becoming the leading biogas company in the Nordics. St1 Biokraft operates an end-to-end biogas value chain, from feedstock sourcing all the way to sales and distribution. St1's sales organization and network will continue the distribution of St1 Biokraft’s products.
In Finland, St1 Biokraft and the dairy and food company Valio have a joint venture to produce liquefied biogas from dairy farm manure and other agricultural by-products as fuel for heavy-duty transport. The joint venture company, Suomen Lantakaasu Oy, will build Finland’s biggest biogas production plant in Upper Savo, Finland.
Suomen Lantakaasu investing 140 million euros in biogas plant projects
Suomen Lantakaasu is a joint venture between St1 Biokraft and Valio, aiming to produce a total of one terawatt-hour of renewable transportation fuel.
Suomen Lantakaasu invested more than EUR 80 million in Kiuruvesi, Finland biogas plant project in 2024. The Kiuruvesi biogas plant is part of the Upper Savo complex that includes the industrial-scale, centralised liquefied biogas production plant in Kiuruvesi as well as three smaller satellite plants in Lapinlahti, Sonkajärvi and Nurmes. The total value of the investment in the Upper Savo complex will be around EUR 100 million. The biogas plant to be constructed in Kiuruvesi will produce liquefied biogas from cattle farm manure in Upper Savo and from other agricultural and food industry byproducts. The plant will be completed in 2026.
In addition to the central plant in Kiuruvesi and the satellite plants, the company is building a central plant of nearly the same size in Nurmo, Finland. The investment in Nurmo is more than 60 million euros. Additionally, the company is exploring new central plant sites in the Ostrobothnia and North Ostrobothnia region.
The planned projects already cover almost half of Suomen Lantakaasu’s total target. Finland’s national biogas target is four terawatt-hours by 2030.
