BP is demonstrating what is describes as 'cutting-edge' biofuel blends in a hundred vehicles now being used in the Olympic Fleet. The fuels include cellulosic ethanol, biobutanol and sugar to diesel.
Cellulosic ethanol is made from purpose-grown energy grasses, which is said to remove the need to produce it from expensive food materials. Biobutanol, made by the advanced fermentation of plant sugars, allows it to fit better into current engines, while sugar-to-diesel fuel, transforms sugar into a renewable fuel that performs like diesel.
Dr Adrian Higson, Head of Biorefining at the National Centre for Bio-Renewable Energy (NNFCC) said: “It is game change changing. Certainly in the case of cellulosic ethanol because of the change in materials that we use to produce biofuels. This can be produced from residues of food materials as opposed to food itself so you don’t have to use as much food or as much land.
“Biobutanol allows for easier use of existing infrastructure and sugar-to-diesel is using biotechnology to make “drop-in” fuel, essentially a replacement for diesel,” he added.
Biofuels currently account for 3 per cent of all transport fuels used around the world. BP says it expects this figure is likely to reach 7 per cent by 2030.
