There are different types of biofuels like biodiesel, rapeseed oil, ethanol, or methane from biogas currently available on the market. Furthermore, synthetic biofuels and BtL-biofuels are currently under development. The advantage of biofuels is their similarity to petrol and diesel in many parameters and can be used in advanced combustion engines with relatively simple adaptation measures.
Apart from biomethane, which is chemically identical to natural gas, biofuels are liquid and therefore easy to store and distributed through the existing network of filling stations. They have a similar high energy density as conventional fuels and do not limit the usual cruising radius.
Biofuels contribute to climate protection releasing only the amount of carbon dioxide during the combustion process which was previously fixed in the plants. Even if their CO2 balance is not completely neutral due to the manufacturing process, they are able to contribute to significant reductions in the greenhouse gas emissions of the transport sector.
For those reasons biofuels make up today about 5.1% of the total fuel consumption in Germany (Source: biokraftstoffe.fnr.de). Despite all, a totally self-contained biofuel supply will hardly be possible in the densely populated countries of Central Europe.
The scarcity of fossil oil is no new concern. Also, the enhancement of the greenhouse effect caused by emissions of carbon dioxide and other greenhouse gases through the burning of fossil fuels causing global warming may change climate and living conditions on Earth.
It is therefore undisputed that we need alternatives to fossil fuels. While the market shares of renewable energies in the heat and electricity sector by now became significant, fuels are still gained almost entirely from fossil resources.
Biofuels from waste, residues, wood and other renewable resources offer conceivable alternatives and will continue to contribute significantly to a sustainable mobility. Plant materials offer the only technically proven and quickly implementable option to substitute fossil fuels in the transport sector.
Today, the mobility of our society is mainly ensured by fossil fuels, especially crude oil whose reserves are limited. Even though nobody can predict exactly when those reserves will be depleted, experts agree about the fact that due to the rising global demand cheap oil is scarce. Therefore it is important to use existing resources carefully and to search for new alternatives.
As already mentioned biofuels contribute to significant reductions in the greenhouse gas emissions in the transport sector releasing only the amount of carbon dioxide during the combustion process which was previously fixed in the plants. Therefore they can slowdown climate change.
