The Paris based Global Bioenergies approach to second-generation isobutene production (using non-edible sources of biomass – e.g. wood chips) has turned out to be hugely popular, earning a €1.4M investment back in June from Bpifrance and a partnership with the car manufacturer Audi to make isobutene-derived Isooctane (a premium drop-in fuel for cars).
According to Biofuels Digest, Isooctanedoes not present the drawbacks associated with alcohol-based biofuels (such as ethanol or isobutanol) which leads to limited blending ratios and a lower mileage per liter. This Green petrol alternative has therefore attracted a lot of attention, given the Green implications it could have for the Automotive industry.
As we wrote before, scaling up of biofuel production is much more complex than it seems, so the next step for the partnership and commercialisation of the new Audi e-benzin is to refine its manufacture for demonstration.
