 ABSTRACT: Globally, transport accounts for about one quarter of the total carbon dioxide emissions. Energy consumption in the transport sector, which is dominated by fossil fuels, is continuously increasing causing various environmental problems. To cope with these problems alternative automotive technologies and alternative fuels are widely supported by different policy measures. It is of high priority to increase use of renewable energy sources in the transport sector. Currently, biofuels are mostly used alternative to conventional fossil fuels. However, with the increasing use of electric vehicles also electricity and hydrogen produced from renewable energy sources are becoming an important means in the decarbonization of the transport sector. Over the last years, biofuels have been supported worldwide. Yet, with the increasing use of biofuels we are facing new challenges, such as to ensure their sustainability and to avoid their competitions with food production. These challenges as well as changeable policy framework resulted in reduction of investment in biofuel technologies over the last decade. Currently, focus is put on electrification of mobility, although, in spite of
