Wärtsilä to supply biogas liquefaction technology to new Swedish project

In Sweden, Wärtsilä will supply its biogas liquefaction technology for an important new project in Mönsterås, Sweden. The system has been ordered by Scandinavian Biogas Mönsterås, a joint venture company between Scandinavian Biogas Fuels (SBF), the majority owner, and local farmers supplying manure and agricultural waste to the project. The plant will produce bioLNG, a substitute for fossil LNG, and will be used as transport fuel for heavy vehicles, thereby contributing to a fossil-free transport system. The order was booked in Wärtsilä’s order intake in December 2022.

The system will have the capacity to produce 30 tons per day of bioLNG. It will be the first project of this capacity using Wärtsilä’s amine scrubber type Puregas CA technology to pre-treat the biogas, which is then liquefied using the company’s mixed refrigerant (MR) process. The system will produce bioLNG with a negative CO2 footprint, and will thus contribute to a net reduction of greenhouse gases in the atmosphere.
