Global Bioenergies, Audi hail first renewable gasoline produced from isobutene

May 18, 2015 |

In Germany, Global Bioenergies (Alternext Paris: ALGBE) and Audi announced that the first batch of renewable gasoline has been produced, converted into isooctane from isobutene, by the Fraunhofer Institute at the Leuna refinery near Leipzig where Global Bioenergies is now building its demo plant.

Isooctane is an additive currently used to improve gasoline quality and could also be used as a standalone fuel. It is indeed the standard from which the octane rating has been defined. In its pure form it would be labelled “unleaded 100”.

Global Bioenergies said that its “technology presents the key advantage that the fermentation process yields a gaseous product which is being dispensed from the liquid phase through spontaneous evaporation. This fact results in a significant reduction of process complexity as well as energy demand for the product separation on the way to isooctane.”

Marc Delcourt, CEO of Global Bioenergies added: “This first batch of renewable gasoline represents a historic milestone. It is the kickoff of a new, large scale, and decentralized industry which respects the environment and will gradually substitute traditional fossil hydrocarbons”.

Reiner Mangold, Head of sustainable product development at Audi declares: “The confirmation that Global Bioenergies’ renewable isobutene is compatible with a commonly used fossil isobutene to isooctane conversion technology represents a key step on our way to Audi ‘e-benzin’. We are now looking forward to working together with Global Bioenergies on a technology allowing the production of renewable isooctane not derived from biomass sources, following Audi’s ‘e-fuels’
strategy.”
