Biogas plant development projects

Gasum continuously upgrade and develop new biogas capacity throughout the Nordics. This is a crucial part of Gasums target of bringing 7 TWh biogas to the market by 2027.

In Finland, a significant investment is aimed at enhancing the Riihimäki biogas plant digestate processing, consequently reducing CO2 emissions by about 1,000 tons a year. The plant expansion is expected to be operational by May 2025. In addition, the Oulu, Vehmaa and Kouvola plants are in various ways upgraded at the moment. The biogas plant in Örebro, Sweden is modernized and upgraded to increase the output of compressed biogas (CBG) production by 17 Gwh. The total project modifications underway in Gasum’s biogas plants will boost production by an additional 100 GWh.

In Sweden, Gasum is planning five new biogas plants, all of which will produce 120 GWh liquefied biogas (LBG) annually. In addition, we are exploring ways to process CBG into LBG from other plants, enhancing efficiency and boosting supply of the liquid form.

The projects in Götene and Borlänge are already in construction, whereas biogas projects in Hörby, Sjöbo and Kalmar are progressing through their respective planning stages.

Meanwhile, in Norway, we are amplifying our renewables capacity. With existing projects in Trondheim region and future plans for additional biogas plants investment. Collectively, these new biogas plants in the Nordics will bolster our production to approximately 1.6 TWh, highlighting our journey towards a cleaner energy future.

Gasum is also exploring the addition of liquefaction capacities to new projects in Sweden. This technology allows us to process compressed biomethane into a liquid form within our plants, enhancing efficiency and boosting supply.

These strategic initiatives align with Gasum's goal to bring 7 TWh of renewable gas annually to the market by 2027. Achieving this goal would mean a yearly cumulative carbon dioxide reduction of 1.8 million tons for Gasum’s customers, marking an impressive stride towards a brighter, carbon-free future.
