The biggest fleet of Hydrogen buses in Europe have hit the roads in Crawley as operators bet big on Hydrogen fuel, rather than electric batteries.

They're more expensive to produce than electric vehicles and refuelling stations are few and far between, but can Hydrogen transport help us on the road to net zero?

On this week's ClimateCast Tom Heap boards a Hydrogen bus to explore how it's improving air quality in Surrey, and he explores if Hydrogen can be used to decarbonise other heavy road transport with David Cebon, director of the Centre for Sustainable Freight at Cambridge University and Helena Bennett from climate policy thinktank Green Alliance.
