Muttenz, January 29, 2014 – A fuel of the future is being introduced to the streets in a fleet test launched by the joined forces of Clariant, Haltermann, and Mercedes-Benz. The Clariant sunliquid® process converts wheat straw into cellulosic ethanol. The company Haltermann then mixes the cellulosic ethanol with conventional fuel components to form the new fuel.
The production of cellulosic ethanol is virtually CO2-neutral, saving almost 100 % of CO2 emissions when compared to gasoline. Sunliquid®20 is 20 % cellulosic ethanol, i.e. the well-to-wheel comparison shows reductions in greenhouse gas emissions of around 20 percent with consistent engine power. There is no competition with food production or for agricultural acreage. A high octane number (RON) of over 100 guarantees optimal efficiency.
Over the next twelve months, test fleet vehicles can be refilled with the new fuel at a specially equipped gas station on the Mercedes-Benz site in Stuttgart-Untertürkheim. The cellulosic ethanol comes from Clariant’s sunliquid® demonstration plant in Straubing, where approximately 4 500 tons of agricultural residues such as grain or corn straw are converted into cellulosic ethanol each year. At the Haltermann plant in Hamburg the bioethanol is mixed with selected components to form the innovative fuel, the specifications of which reflect potential European E20 fuel quality.
