The company currently has two installed fueling stations at Heathrow and East London with plans for a second East London station besides a centrally located one, as part of the Clean Hydrogen In European Cities Project.

A fifth station is just north of London at the Millbrook Proving Ground in Bedford is also expected to be part of the network.

Air Products hydrogen energy systems business development manager Emma Guthrie speaking on the project remarked that the future of hydrogen transport is based around clusters of hydrogen infrastructure for which London is well suited.

"Air Products is providing the hydrogen and the fuelling station for this project because we believe it is exactly these kind of innovative ideas that will get the general public, industry and Government to take notice of hydrogen.

"If the UK is to cut emissions from transport then hydrogen has to be part of the transport mix," added Guthrie.
