Biofuel for buses

Hydrocarbon Engineering,

A new liquefaction plan in Norway will convert household food waste into liquid biogas in volumes great enough to fuel 135 buses. As a result, CO2 emissions will be reduced by 10 000 tpy. Particle emissions will also be reduced significantly along with noise levels.

The plant

The biogas liquefaction plant, which has been delivered by Wartsila to Cambi AS, is inaugurated on 12th February. The plant is to be operated by Cambi AS on behalf of EGE and the City of Oslo, putting the region at the forefront of environmental innovation. EGE produces environmentally friendly energy from waste and is under the supervision of the City of Oslo’s Department of Environmental Affairs and Transport.

The plant is in Nes, Romerike, close to Oslo and when fully operational will treat 50 000 tpy of food waste to produce approximately 14 000 m3/d of biomethane. The liquid biogas (LBG) can be efficiently transported for use as fuel.


Jannicke Gerner Bjerkas, Director of Communications and CSR, EGE said, ‘this plant will mean that 135 Oslo region buses will be able to run on biogas. As a result, CO2 emissions will be reduced by some 10 000 tpy and particle emissions will also be significantly lowered. The air will be cleaner and noise levels will be reduced, and these are benefits that everyone in the region will enjoy.’

Tore Lunde, Managing Director, Wartsila Oil & Gas Systems said, ‘we are proud and delighted to be involved in this groundbreaking project to produce a new, renewable, and environmentally sustainable transportation fuel. There is huge potential for the use of LBG from renewable energy sources as fuel for trucks and buses, and this project is an important step forward in developing this market. This same technology can also be used in small liquefaction projects with other sources of gas as well, and we are excited about the future possibilities.’
