Aberdeen rolls out world’s first hydrogen double decker

Manufactured by Wrightbus, the zero-emission double decker was modified with the help of Luxfer Gas Cylinders, whose multi-cylinder system stores low-pressure hydrogen at the rear of the bus. The hydrogen feeds an onboard fuel cell which in turn charges a battery pack beneath the vehicle floor, which then powers a compact electric motor to drive the bus. The vehicle is one of a 15-strong fleet that Luxfer has converted for Wrightbus.

“Luxfer has pioneered hydrogen storage systems and valve technology, and we were brought into this project by Wrightbus in 2017 to help design how the hydrogen system could work to deliver the best range, in a cost effective solution,” said Mark Lawday, director at Luxfer Gas Cylinders.

“Aberdeen has been at the forefront of hydrogen, proving it is viable, and we worked with them on introducing an original fleet of 10 hydrogen buses to the city too. It’s fantastic that these new double deckers will begin their journeys with passengers soon.”
