Audi is testing a new e-fuel developed in partnership with Global Bioenergies.

The ongoing collaboration between the two has reached a significant milestone, with 60 litres of synthetic e-benzin (e-gasoline) ready for testing. The process to make it involved taking renewable isobutane produced from the Leuna Demo plant, which is operated by Global Bioenergies, and converting it into ‘high-performance gasoline additives’ at the Fraunhofer Institute.

“Like all Audi e-fuels, the new fuel has many advantages. It isn’t dependent on crude oil, it is compatible with the existing infrastructure and it offers the prospect of a closed carbon cycle,” said Reiner Mangold, Head of Sustainable Product Development at AUDI AG.

Global Bioenergies will further enhance its e-fuel production capabilities next year with the introduction of a ‘dedicated fuel production unit’ at its Leuna Demo plant.

“We are proud to have met this milestone based on renewable isobutene-derived gasoline. Audi brings to our technology development a clear path to market perspective,” added Marc Delcourt, CEO of Global Bioenergies.
