Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment he has made of the long-term potential for hydrogen to lower the emissions required for the heating of residential properties.

The Department is currently undertaking work to strengthen and assess the evidence on the range of potential approaches to decarbonising heat, including on the use of hydrogen. There are a number of technologies with the potential to make a major contribution to decarbonisation. As well as hydrogen, these include, heat pumps, hybrid gas and electric heating systems and district heating networks. I plan to publish a report on the Department’s review of the evidence later this year.

The Department has also commissioned the Hy4Heat project which aims to provide essential technical evidence on the use of hydrogen for heat in buildings. This will include developing and testing hydrogen boilers. The project has a total budget of £25m and will run until 2021.
