Since the early 1990s, biogas consumption in Linköping has been increasing. With the expansion of infrastructure and vehicles capable of using biogas, Linköping is a leading model for biogas vehicles and fleet worldwide. Over the past few years biogas production has grown at a nearly constant rate of 20%. Since the start when only a limited amount of biogas was delivered primarily to the bus fleet, over 8.5 million m3 were delivered in 2009 (Svensk Biogas, 2009). Currently biogas is used in the public transport sector, vehicle fleets and more than a thousand personal vehicles. This development, along with the use of ethanol and biodiesel has led to a large increase in the use of renewable fuels in the municipality. While biogas and other renewable fuels make up only a small portion of the vehicle fuels consumed in the municipality, this portion continues to grow.
Regional and national administrations have been challenged with European directives to include renewable energy in many sectors. In the transport sector, according to the European Directive 2003/30/EC all countries are to have a 5.75 % share of renewable energy in their transport sector by 2010 (EU, 2003). Thereafter, every member state is required to have a minimum of 10% in 2020. To meet these goals, member states are looking for solutions in various technologies, i.e. biofuels, hybrids, electric vehicles and hydrogen fuel cells. Currently, biofuels are being employed in nearly all the member states to fulfill the targets, with biogas, ethanol and biodiesel being most common. Sweden is a leader in the use of ethanol, while municipalities such as Linköping have put an emphasis in making use of industrial wastes to produce biogas. Locally produced renewable energy will thus provide vehicle fuel for the municipality of Linköping in order to reduce environmental impacts and meet vehicle fuel targets.
Linköping has become a benchmarked city in the use and production of biogas. However, how much biogas and other renewable fuels does Linköping currently employ? The aim of this research paper is to analyze the use of renewable and fossil fuels in the region in order to quantify the percentage in relation to the European Directive 2003/30/EC. The research project will provide details regarding the share of petrol, diesel, biodiesel, ethanol and thereafter biogas in the current vehicle fuel consumption.
