From Ballymena to London | England’s first hydrogen double deckers hit the streets


Mayor launches England’s first hydrogen double deckers to reduce London’s carbon footprint and tackle toxic air in the capital


The Mayor of London, Sadiq Khan, will today launch England’s first ever hydrogen double decker buses, marking another major step towards making the bus fleet zero-emission and cleaning up London’s toxic air.

The 20 new environmentally-friendly buses, the first of their kind to be launched in England, built by Wrightbus, will produce no pollution from their exhausts and join more than 500 electric buses in the core fleet which are already zero-emission. The new hydrogen fuel cell double decker buses are first being introduced on route 7 between East Acton and Oxford Circus.

Hydrogen used in a fuel cell is free from harmful emissions. The only by-product is water from the chemical reaction of hydrogen with oxygen from air, a process that produces electricity to power the bus. The buses will help clean up the air and improve the health of Londoners by reducing the level of harmful nitrogen oxide in the air. Passengers will benefit from smoother, quieter journeys due to fewer vibrations and will be able to take advantage of free-to-use USB charging points.

The Mayor’s green transport investment is also supporting jobs across the UK. The buses were manufactured by Wrightbus in Northern Ireland, helping to create new jobs, and the gas cylinders are manufactured by Luxfer in Nottingham. The hydrogen for the buses is currently being produced at Air Liquide’s plant in Runcorn, harnessing waste hydrogen as a by-product from an industrial chlor-alkali plant. Oxford-based Ryze Hydrogen is responsible for transporting the fuel to the fuelling station. From 2023, the hydrogen will be even greener as it will be produced by electrolysis powered by a direct connection to an offshore windfarm.

A new, state of the art fuelling station completed by Danish engineering firm Nel Hydrogen will top up each hydrogen fuel cell bus just once per day in as little as five minutes.

The Mayor will today visit Perivale bus depot in Ealing to see the new hydrogen double decker and new hydrogen refuelling station.




The Mayor of London, Sadiq Khan, said:


“We have made real progress in London to clean up our air, but we still have a long way to go because toxic air pollution in our city is still leading to thousands of premature deaths every year and is stunting the growth of children’s lungs. As part of our world-leading ongoing efforts, I’m proud to announce England’s first hydrogen double decker buses, which don’t produce any harmful emissions, will now be put into service.

“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.

“I’ve worked hard to ensure TfL’s entire core bus fleet across London now meets the ULEZ standards, and this includes 500 electric buses. Our new investment in hydrogen buses will move us even closer to our ambition of making all London buses zero-emission by 2030.”

Wrightbus CEO, Buta Atwal, said:


"At Wrightbus, we're incredibly proud to be launching our world-first zero emission hydrogen double deckers onto the streets of London to help turn its iconic red buses green.


“London residents - and visitors to the capital from around the world - can experience what it's like to ride in a UK-made hydrogen-fuelled vehicle that produces no harmful emissions from its exhaust.


“Thanks to TfL's visionary approach, the city will have the first fleet of hydrogen double deckers in England and the benefits to the city in terms of CO2 reduction will be significant. We hope that other cities around the country will follow London's lead and help us in our ambition to decarbonise public transport and improve air quality.”
