Shell teams with bio-bean to fuel London buses with coffee-based B20

In the UK, Shell and bio-bean announce that together they are helping to power some of London’s buses using a biofuel made partly from waste coffee grounds. The B20 biofuel contains a 20% bio-component which contains part coffee oil. The biofuel is being added to the London bus fuel supply chain and will help to power some of the buses; without need for modification.

The grounds are dried and processed before coffee oil is extracted. bio-bean works with its fuel partner Argent Energy to process this oil into a blended B20 biofuel. About 6,000 liters of coffee oil has been produced, which if used as a pure-blend for the bio component and mixed with mineral diesel to form a B20, could help power the equivalent of one London bus for a year.
