Question to the Department for Transport:

To ask His Majesty's Government whether they favour the deployment of hydrogen fuel cells in trains and heavy goods vehicles in replacement of diesel engines.

The Government recognises the important role of hydrogen in decarbonising the economy, and expects hydrogen and its derivatives to play a role in sectors where there are limited alternative solutions with each transport mode driving progress on the solution that is most appropriate to them.

The Department is supporting the transition to low carbon fuels in surface transport through the Renewable Transport Fuel Obligation, alongside driving hydrogen research, development and deployment through programmes such as the SAF and ZEV Mandates, ZEHID, UK SHORE, the Advanced Fuels Fund, and the CAA’s Hydrogen in Aviation Regulatory Challenge. The Government will also be publishing a renewed Hydrogen Strategy in 2026 to sharpen priorities and deepen industry collaboration, alongside a forthcoming Zero Emission HGV and Coach Infrastructure Strategy.
