In long term the greenhouse gas (GHG) emissions have to be reduced stringently. One way to achieve this goal is the substitution of fossil fuels through CO 2 -neutral fuels. There are gaseous and liquid fuels possible to use. Liquid fuels have advantages in terms of logistics, energy densitiy and conventional storage technology. Fuels from biomass are critically evaluated because the savings in greenhouse gas emissions remain marginal considering the changes in land use and bring significant degradation of fuel quality with it. [1,2] An EU study including the indirect land use changes (ILUC) shows that Biodiesel leads to a CO 2 increase of 9 to 20 %, compared to using mineral oil-based diesel fuel.
