London buses to use Honeywell Enraf biodiesel blending technology

By Honeywell | December 02, 2013

Honeywell announced it has been selected by Transport for London to provide its Fusion4 technology to allow biofuels used in London buses to be blended directly at London bus depots, rather than the previous method of mixing with standard diesel at refineries in Scotland and transported to the capital. The solution is currently being piloted at the Barking bus depot.

The new blending capability will reduce the number of fuel delivery vehicles needed to supply biodiesel to the London buses. Road vehicles account for about 80 percent of transport-related CO2 emissions in London, and with more than 2 billion passenger journeys a year, London’s bus network is one of the busiest in the world.

“Using Honeywell’s fuel blending technology, Transport for London will not only see a reduction in fuel delivery costs, but will be able to vary, as needed, the precise mix of biodiesel for its buses,” said Richard Thompson, general manager, Honeywell Enraf. “This mix is important because it allows the bus operator to maximize the amount of greenhouse gases saved without compromising performance.”

The Barking depot took delivery in September of Honeywell Enraf’s Fusion4 Microblender system—a preassembled, skid-mounted system for blending including a storage tank that will be delivered to the site ready to use. With the company’s Fusion4 blending controller, operators at the depot can easily ensure an accurate mix through intuitive icon-driven menus and running screens.
