Wärtsilä Gas Solutions, part of Finland-headed international energy and marine technology group Wärtsilä Oyj has announced that it will supply and install biomethane liquefaction solutions for two large-scale biogas projects in Finland.
The biomethane liquefaction plants have been ordered by Suomen Lantakaasu Oy, a joint venture between biomethane company St1 Biokraft and dairy and food company Valio.
The two projects, the value of which has not been disclosed, will each have the capacity to produce 25 tonnes of bioLNG per day.
Reduce the carbon footprint of dairy production
The feedstock for the biogas will be mainly livestock manure and food processing waste. The digestate, an odour-free biofertilizer, will be used by the farmers who supply the manure.
When operational, the plants will enable more widespread use of a biogas-powered transport fleet.
By utilising manure in biogas production, the carbon footprint of milk production is significantly reduced, when the emissions reduction of both agriculture and transport is taken into account.
Suomen Lantakaasu has strong ambitions in building a biogas production network in Finland and enabling wider use of biogas fuel in transport applications. Wärtsilä’s deep experience and successful track record for high-capacity biogas upgrading and liquefaction plants is highly valuable to our projects, said Leena Helminen, CEO of Suomen Lantakaasu.
Greenfield projects
The Suomen Lantakaasu biogas plants are greenfield projects and will be built in Nurmo and Kiuruvesi, located in western and central parts of Finland, respectively, and are expected to be in operation by the second half of 2026.
In addition to the biogas upgrading and liquefaction plants, Wärtsilä will also supply 300 m3 capacity storage tanks, as well as an export station.
Previously, Wärtsilä has only supplied biogas upgrading and biogas upgrading plus liquefaction plants to St1 Biokraft in Sweden and Norway.
Wärtsilä’s focus is very much on shaping decarbonisation. Our bioLNG plants are a central pillar of this strategy. These biogas upgrading and liquefaction plants will have the capacity to produce significant levels of green fuel and thus support Suomen Lantakaasu in their journey, commented Magnus Folkelid, Sales Manager, Wärtsilä Gas Solutions, Biogas.
