Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate he has made of the number of hydrogen fuel cell electric vehicles on UK roads.

Hydrogen fuel cells in vehicles is an exciting technology with the potential to revolutionise transport. Though the number of hydrogen fuel cell electric vehicles on UK roads is still in the early hundreds, we have seen some exciting developments with the technology.

The Mayor of London recently announced the first fleet of hydrogen double decker buses in the world and a number of companies are also developing hydrogen fuelled trains which may one day run up and down our network. We are committed to working with industry to identify how we can use hydrogen-powered vehicles to decarbonise our future transport system.
