Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government, in relation to their targets for decarbonisation by (1) 2030, and (2) 2035, what approximate proportion of homes they estimate are likely to be powered by (a) hydrogen-based gas, (b) air or ground source heat pumps, and (c) by other forms of electrification.

A range of technologies will be required to decarbonise the way we heat our homes. The precise mix of technologies in 2035 is unclear, in part because strategic decisions on the role for hydrogen heating are still to be taken. Heat Pumps and Heat Networks will have an important role to play in all future scenarios with at least 7.1 million homes using heat pumps in 2035.
