Wärtsilä to supply bio-LNG tech for Finnish biogas projects
Finnish technology group Wärtsilä has won a contract to deliver biogas upgrading and bio-liquefied natural gas production systems for two facilities in Finland being developed by joint venture biomethane firm Suomen Lantakaasu Oy.
The two plants will produce liquefied biomethane (bio-LNG) by upgrading raw biogas by removing CO2 and other impurities. They will then liquefy the methane for use as a low-emission transport fuel.
Located in Nurmo and Kiuruvesi, the projects are expected to produce 25 tonnes of bio-LNG per day, using manure and food processing waste. The remaining by-product will be repurposed as odour-free biofertiliser, returned to the farmers supplying the feedstock.
