The 20 buses will join over 500 electric buses in the core fleet which are already emission-free, aiming to improve the city’s air quality by reducing pollution and forming part of the UK’s wider net zero ambitions.
Manufactured by Wrightbus in Northern Ireland, with gas cylinders manufactured by Nottingham-based Luxfer, the hydrogen fuel cell powered buses will offer ‘smoother, quieter’ journeys for passengers in addition to being entirely free from harmful emissions, the only by-product being water from the chemical reaction of hydrogen with oxygen from the air.
Supported by over £12m funding from TfL, the Fuel Cells and Hydrogen Joint Undertaking (FCH JU), the Innovation and Networks Executive Agency (INEA) and the Office of Zero Emission Vehicles, the buses form part of the FCH JU-funded Joint Initiative for Hydrogen Vehicles (JIVE) project which seeks to deploy 139 new zero-emission fuel cell buses and associated refuelling infrastructure across five European countries.
The buses use hydrogen produced at Air Liquide’s plant in Runcorn, which harnesses waste hydrogen as a by-product from an industrial chlor-alkali plant. Oxford-based Ryze Hydrogen will transport the fuel to the fuelling station. From 2023, the hydrogen will be produced by electrolysis via a connection to an offshore wind farm.
A new fuelling station completed by Danish engineering firm Nel Hydrogen will top up each hydrogen fuel cell bus once per day in around five minutes.
Commenting on the launch, Khan said: “Our investment in these hydrogen buses is not only helping us to clean up London's air, but is supporting jobs and local economics across the UK. This is a great demonstration of how tackling air pollution and the climate crisis and boosting economic growth is about regions working together, investing in the very latest technology.”
