To ask the Secretary of State for Transport, whether his Department has made a comparative assessment of the (a) costs and (b) benefits of (i) hydrogen and (ii) electricity as energy sources to power motor vehicles.
2 December 2020
In 2018, the Department for Transport published the outputs of the Transport Energy Model. The model provides a clear assessment of the relative environmental impacts of a range of fuel and powertrain options for cars, vans, buses and heavy goods vehicles over the period to 2050, including battery electric and hydrogen fuel cell vehicles. The Department is further assessing the potential role of hydrogen and electricity in vehicles and this will be published in the Transport Decarbonisation Plan by Spring 2021.
