Clariant, Swiss leading global specialty chemicals company, together with Mercedes-Benz and Haltermann Carless, a well-established HCS Group brand, tested the use of sustainable cellulosic ethanol from agricultural residues in a fleet test with Mercedes-Benz series vehicles over a period of 12 months for the first time in Germany.
A fuel of the future is being introduced to the streets in a fleet test launched by the joined forces of Clariant, a globally leading specialty chemicals company, based in Muttenz near Basel (Switzerland), Haltermann, one of the leading suppliers of high purity refinery chemicals used in the automotive, pharmaceutical and cosmetics industries, based in Hamburg (Germany), and Mercedes-Benz (Daimler AG). 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 % 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.
