In organic farming, the aim is to have production based on the use of natural, biological and renewable resources. However, organic farming in Sweden consumes large amounts of diesel oil as tractor fuel. Since 2002, the Dept. of Energy and Technology has been working together with JTI (Swedish Institute of Agricultural and Environmental Engineering) on the Green Tractor project. The aim is to develop and analyse systems for rendering organic farms self-sufficient in renewable tractor fuel. Systems capable of being implemented at present have been studied, as well as future solutions such as hydrogen cells
