London's buses turn to coffee to power them through the day


B20 biodiesel with a 20% bio-component that contains part coffee oil is being added to the London bus fuel supply chain, the companies said.

In an attempt to explore fossil fuel alternatives, a partnership between Shell, Argent Energy, biofuel company Bio-Bean, and Transport for London, the city's iconic double-decker buses will soon run on "B20 Biofuel", a proprietary combination of oil from coffee ground extracts and diesel.

Biofuels produced from cooking oil and tallow from meat processing already powers some of London's 9,500 buses, according to the BBC. According to official figures in 2015, London's buses used 240 million liters of diesel fuel a year. This is then mixed with other fats and oils to create a 20 percent biocomponent of B20 fuel.

Shell's involvement in the venture forms part of the oil company's #makethefuture energy relay, which supports entrepreneurs in the energy sector.

With the average Londoner drinking 2.3 cups of coffee a day, more than 200,000 tonnes of waste is produced that would otherwise end up in landfill.

The fuel, known as B20 biofuel, provides a cleaner, more sustainable energy solution for buses across London's network by decreasing emissions.

Sinead Lynch, Shell's United Kingdom country chair, said: "We're pleased to be able to support bio-bean to trial this innovative new energy solution which can help to power buses, keeping Londoners moving around the city - powered in part by their waste coffee grounds".

Sinead Lynch, Shell UK country chair, said, "When it comes to clean energy, we are always looking for the next inventive solution". Bio-Bean is also targeting the U.S. for its coffee-fused fuel source.

In fact, if everyone in London just drank a mere 12 cups of coffee a day, we'd be able to power every single bus in London for a year.
