Ingolstadt-based Audi has reached an important milestone in its efforts to develop synthetic fuels (e-gasoline and e-diesel). Working with Global Bioenergies S.A. and the Fraunhofer Center for Chemical-Biotechnological Processes (CBP), both in Leuna (Saxony-Anhalt), the company has produced enough e-gasoline – 60 liters – to perform combustion and emission experiments in a test engine. This represents the largest batch of e-gasoline ever produced. The low-pollutant fuel was made from biomass in a two-step process. The goal is to eventually use carbon dioxide and hydrogen from renewable sources rather than biomass to make such fuel. The carmaker is also experimenting with synthetic diesel fuel made at the Sunfire Dresden pilot plant.
