During the 80th International Green Week (Grüne Woche) event in Berlin, Volkswagen pushed for the development of a European E10 (10% ethanol) standard for gasoline.
The current European fuel standard DIN EN 228 specifies 15% ETBE (ethyl tertiary butyl ether), or 5% ethanol by volume. The objectives of the EU biofuel directive for 2010, however, require a higher proportion of up to roughly 9% ethanol by volume in gasoline. Volkswagen is therefore actively supporting the drafting of a suitable European standard for the future E10 fuel.
Volkswagen’s innovative drive concepts are already capable of using an up to ten percent volume blend of bioethanol in petrol (E10) within the specifications of a future fuel standard. Volkswagen is promoting the increasing spread of biogenic fuels with its modern engine technology that is prepared for the use of ethanol blend fuels. This is an important element in our future-oriented fuel strategy.
Greater use of biomass for fuel production, as set out in the federal government’s fuel strategy, makes a major contribution to energy security and CO2 reduction. Volkswagen is backing this strategy with its support for higher ethanol concentrations of up to ten percent in petrol ethanol blends. This is another step in our fuel strategy towards the introduction of 2nd generation biofuels with much higher rates of CO2 reduction, such as ethanol from lignocellulose or SunFuel, a synthetic diesel fuel produced from biomass.—Matthias Rabe, Head of Group Research at Volkswagen AG
Volkswagen noted that its new TSI dual-charged, gasoline direct-injection engine (earlier post) is E10 ready.
Volkswagen backs a uniform system of tax on biofuels and their blends according to sustainability criteria.
To achieve the goals of the European Parliament’s EU Biofuel Directive 2003/30/EG of 5.75% renewable fuels by the end of 2010, Volkswagen supports broader use of gasoline and biodiesel blends as opposed to use of pure biofuels. For Volkswagen, the broad Europe-wide use of ethanol-blended fuel is the most economically effective way to achieve a wide-scale and quick introduction onto the market by 2010.
