Fordonsgas från deponier : en potentialstudie i Biogas Öst-regionen

Abstract: The demand for biogas as vehicle fuel has risen sharply and there is a great need for increased production. A possible addition of vehicle gas can be produced by upgrading landfill gas which is formed by degradation of organic waste. This thesis investigates the potential of producing vehicle fuel from landfill gas in the region of Biogas Öst. In 2008, an amount of 32 million Nm3 landfill gas was extracted in the region. This level can be maintained for another ten years if the efficiency of gas extraction is improved. The annual production will decrease with time since landfills aren’t allowed to receive more organic waste. Landfill gas is hence a large but not lasting source of vehicle fuel. The amount of available landfill gas that is possible to upgrade to vehicle gas is limited by technical and financial issues. With certain limitations taken into account, an estimation of the regions potential gives an annual production of 8.2 million Nm3 vehicle gas. This means that more than 7 000 private cars or 250 buses could be operated with vehicle fuel from landfills in the region.
