Nottingham City Transport (NCT) has taken delivery of its first new bio-gas double deck buses from its latest £7 million investment in 23 brand new buses. Quadrant Transport looks at how the bio-gas buses will support the decarbonisation of Nottingham.

NCT already operates the world’s largest fleet of bio-gas double-deck buses at 120 buses in Nottingham, with the bio-gas being produced naturally through anaerobic digestion, using food waste, farm waste and sewage.

The methane that is emitted from the digestion process is captured, treated, and turned into fuel. This use of bio-gas has enabled NCT to halve its diesel consumption from 8 litres to 4 million litres per year.

Existing Buses Have Already Contributed To Improving Air Quality

Already running on three-quarters of NCT’s double-deck services, the current fleet has clocked up over 15 million miles in service since first appearing on Nottingham’s streets five years ago.

Nottingham City Transport's existing buses have prevented over 26,000 tonnes of CO2 from being emitted.

They have been essential in contributing to improving the city’s air quality, as the existing buses have prevented over 26,000 tonnes of CO2 from being emitted, as well as reduced NOx emissions by 180,000kgs.

Head of Engineering at NCT, Liam O’Brien said: “NCT is committed to minimising its impact on the environment and we already operate one of the greenest bus fleets in the country.”

Our bio-gas fleet has contributed to much improved air quality in and around Nottingham and this investment in 23 further bio-gas buses will improve it further.

Decarbonising The Transport Industry’s Operations Is Vital To Reaching Net Zero

The engines and chassis of the E nviro400CBG City bio-gas buses have been developed by Swedish giant Scania and are bodied in Britain by the country’s largest bus manufacturer, Alexander Dennis Limited (ADL).

Sales Director for Bus, Coach and Power Solutions at Scania UK, Mark Oliver, said: “We are delighted to have provided the chassis and powertrains underpinning the world’s largest fleet of bio-gas double deck buses.

“This project is a culmination of seven years hard work between NCT, ADL and Scania to get these buses on the road and the right infrastructure in place.”

At Scania, we are committed to help businesses decarbonise their operations, which is why we are proud to see this project come to fruition.

All 23 of the bio-gas buses are expected to be in service by the end of August.
