LPG and CNG as fossil fuels are available in Europe. CNG from biomass is also a clean energy strategy that is becoming increasingly available in Europe. When the vehicle is optimized to run on gas as the preferred mode, compression ratio and other parameters can be adjusted for improved efficiency. One example is the mono-fuel versions offered by Opel. In the long run, it makes sense to increase the use of renewable fuels. Bio-Diesel and ethanol are also very important energy carriers. We need to work on the efficiency of the processes to produce these fuels, and we need to improve the yield in the fuel production. Overall, we look to governments to put in place positive policy frameworks. This encourages the research, development and commercialization of even more environmentally friendly second generation biofuels like hydrogen, methanol, ethanol, dimethyl ether (DME) and Biomass-to-Liquids (BTL). The political engagement should be reflected in the tax structure for the fuels and vehicles as well as in a widespread distribution network for these fuels.
The preferred fuels in the different regions will depend on the available processes for the production of the fuel. We will continue to see diesel-like and gasoline-like fuels. This is why FISITA will push the further development of both the diesel and the gasoline engines.
