Volkswagen has been testing the newly developed R33 BlueDiesel fuel blend at its in-house filling station in Wolfsburg since January 2018. The fuel, jointly developed by Volkswagen, the Coburg University and other project partners, contains up to 33% renewable components based exclusively on residual and waste materials and enables CO2 savings of at least 20% compared to conventional diesel thanks to the use of biofuels.
Volkswagen employees tested the new fuel initially. Over a period of nine months, they filled up company vehicles with R33 BlueDiesel only.
The current supplier since January 2018 is Shell Global Solutions in cooperation with Tecosol and Neste, who supply fuels certified according to European standards.
Drop-in renewable fuel leader Neste began testing its Diesel D33 blend—26% NExBTL renewable diesel, 7% conventional biodiesel (FAME) produced from used cooking oil, and 67% fossil diesel—in Germany in 2013, including a demonstration project involving 280 vehicles—including buses, cars, and trucks—in Coburg in Bavaria aimed at commercializing the fuel.
R33 BlueDiesel complies with the diesel standard DIN EN 590 and fulfills all criteria for use as a standard fuel without having to meet further requirements. This fuel is of particular interest to Volkswagen’s major and fleet customers whose diesel vehicles cover many kilometers a year as its use helps to achieve climate protection goals.
Following the successful test phase, R33 BlueDiesel is now being used permanently at Volkswagen’s filling stations in Wolfsburg, and a test operation has also been started at the Volkswagen plant in Salzgitter. This summer, it was also introduced at other project partners such as Robert Bosch GmbH. Introduction at further locations is planned.
The response to R33 BlueDiesel is very encouraging for Volkswagen and its project partners. R33 BlueDiesel is particularly suitable for companies that rely on diesel vehicles due to their long fuel ranges and still want to achieve their environmental goals. We are preparing for a significant increase in demand for liquid fuels from residual materials and for advanced biofuels in the medium term. I hope that public filling stations will also be offering R33 as “Green Premium” in the near future.—Volkswagen project manager Prof. Thomas Garbe
