Fuel Cells: Carbon Emissions
- Question
-
To ask the Secretary of State for Transport, what assessment has been made of the role that hydrogen fuel cell vehicles could play alongside electric vehicles in achieving net zero transport, particularly in light of vehicle weight, raw material availability and grid capacity constraints.
- Answer
-
The Government is technology neutral in its approach to road decarbonisation. Road transport accounts for 90% of domestic transport greenhouse gas emissions, making the transition to zero emission vehicles essential to achieving our climate obligations.
The market will decide which zero emission technologies are ultimately successful, and it is likely that battery electric vehicles will be the most cost effective and practical in the majority of applications. Battery electric vehicles with vehicle to grid capability are likely to play an important role in managing grid capacity, providing grid flexibility. However, hydrogen technology may be adopted in some cases where it makes sense to do so.
