The Government supports the use of hydrogen trains on the railway where appropriate to deliver our legally binding target to reach net-zero greenhouse gas emissions from the UK by 2050. Network Rail is developing a Traction Decarbonisation Network Strategy which will examine which parts of the network are best suited to use of hydrogen trains, as well as battery and electrification. This will inform Government decisions in 2020. Our innovation programmes have supported the development of hydrogen technology, such as the ‘Hydroflex’ train, and continue to provide funding opportunities for innovative environmental projects. The Government is also funding work on safety and wider issues that will have to be considered to allow the smooth entry into service on the network of hydrogen trains.
