Wärtsilä to produce biofuel for buses in Norway

Biogas liquefaction plant, delivered by Wärtsilä to the Norwegian Cambi AS, begins operation.

The biogas liquefaction plant, operated by Cambi AS on behalf of EGE (Waste-to-Energy Agency) and the City of Oslo, will produce biomethane from household food waste to be used as biofuel for buses in Oslo. The plant is located in Nes, Romerike, an agricultural region close to Oslo. When fully operable it will treat 50,000 tons of food waste a year to produce around 14,000 Nm3 (normal cubic meters) per day of biomethane. The liquefied biogas can be efficiently transported for use as fuel.

Jannicke Gerner Bjerkås, director of communications and CSR, Waste-to-Energy Agency, City of Oslo, said the buses' conversion to biogas means CO2 emissions will be reduced by some 10,000 tons a year, and that particle emissions will be significantly lowered as well. "The air will be cleaner and noise levels will be reduced, and these are benefits that everyone in the region will enjoy," Bjerkås added.

Tore Lunde, managing director, Wärtsilä Oil & Gas Systems, believes there is huge potential for the use of liquefied biogas from renewable energy sources as fuel for trucks and buses. "This same technology can also be used in small liquefaction projects with other sources of gas as well," Lunde added.
