A fleet of 30 bio-gas double-decker buses will take to the road in Nottingham from this summer, following a 17 million investment.
The buses, which are powered using gas produced by anaerobic digestion of food waste and sewage, with a reported reduction in NOx emissions of around 36,000 kg across the citys bus fleet according to Nottingham City Transport (NCT).
NCT, working in partnership with Nottingham city council successfully secured 4.4 million in grant funding for the new vehicles from the Governments Office for Low Emission Vehicles (OLEV).
A further 12.4 million has been invested in the vehicles and the gas fuelling infrastructure needed to fill the fleet at the citys Parliament Street Garage. Roadgas and ZF Transmissions have worked alongside NCT to establish the fuelling infrastructure.
The engines and chassis the Enviro400CBG City vehicles have been developed by Swedish firm Scania and are bodied in Britain by Alexander Dennis Limited (ADL).
The first 30 bio-gas buses will begin operating on routes6, 10, 24, 25 and 44 from the summer, with a further 23 being added to the fleet early next year on routes 36 and 45.
Commenting on the new fleet NCT Engineering Director, Gary Mason, said: We are hugely proud of our new bio-gas buses. This is the largest order for gas double decks in the world and is the culmination of our extensive research into alternative fuels.
Bio-gas is produced naturally through anaerobic digestion, using food waste, farm waste and sewage. The methane emitted from the digestion process is captured, treated and turned into fuel. When this fuel is used, emissions are 84% lower than their diesel counterparts, thereby making them from Well-to-Wheel the greenest buses on the road.
Tony Tomsett, bus, coach and engine sales director for Scania (Great Britain) Limited added: Nottingham City Transport has a long-standing reputation for innovation and is once again leading the way with these vehicles, which represent the worlds largest ever order for bio-gas-fuelled double-deck buses.
We now look forward to working with the Nottingham team to ensure the city realises the maximum environmental and operational benefits offered by these vehicles.
Richard Matthews, sales director at ADL, commented: Were delighted to partner with NCT and Scania on this significant order which responds to the citys requirements to improve street level air quality, while delivering a first class on-board experience for passengers.
Weve seen the increase in bus ridership our Enviro400 City styling and enhanced interior specifications bring USB power sockets, comfortable seats and a bright, airy environment from the increased glazing all add to the premium feel which we know passengers appreciate.
