August 1, 2022. United Kingdom’s Nottingham City Transport (NCT) has taken delivery of its first new biogas double deck buses from its latest £7 million investment in 23 brand new buses.
NCT already operates the world’s largest fleet of biogas double decks in the world at 120 buses.
Biogas 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 and the use of biogas has enabled NCT to halve its diesel consumption from 8 million litres to 4 million litres per year.
The biogas buses already run on three quarters of NCT’s double deck services and the current fleet has clocked up over 15 million miles in service since first appearing on Nottingham’s streets five years ago, in July 2017.
In addition to their smart, stylish design and comfortable ride, the biogas fleet has contributed to improving Nottingham’s air quality. The existing buses have prevented over 26,000 tonnes of CO2 being emitted, as well as reducing NOx emissions by 180,000kgs.
NCT’s Head of Engineering, Liam O’Brien said, “NCT is committed to minimizing its impact on the environment and we already operate one of the greenest bus fleets in the country. Our biogas fleet has contributed to much improved air quality in and around Nottingham and this investment in 23 further biogas buses will improve it further”.
