Fuels based on renewable energy sources (RES) such as a variety of first and second generation biofuels as well as electricity and hydrogen from RES, are considered an important means of coping with the environmental problems of transport. The objective of this paper is to investigate the “renewable fuels” from economic, energetic and ecological perspective within a dynamic framework until 2050. The key results show that all fuels analysed have lower CO2 emissions than gasoline, but drawbacks include the high costs of hydrogen- and electricity-driven vehicles. By 2050 however these costs could be reduced due to technological learning effects and efficient policy measures (e.g. CO2-based tax). We conclude that “renewable fuels” will only play a significant role if CO2 taxes, intensified R&D and technological learning are strategically implemented. •Electricity and H2 from renewables show ecologically the best performance.•In 2010 there are huge economic and ecological differences between considered fuels.•In 2050 cost differences between alternative and fossil fuels are much lower.•The development of investment costs of vehicles is more important than fuel costs.•Major uncertainty for future of renewable fuels are battery and fuel cell costs.
