Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether he has considered the potential merits of promoting the use of hydrogenated vegetable oil for domestic heating.

The Government is currently investigating what role renewable liquid fuels such as Hydrotreated Vegetable Oil could play in the future low carbon heating mix. As sustainable biomass is a limited resource, the Government believes that the use of biofuels in heating is likely to be limited to properties where heat pumps cannot be used. The Government will prioritise its use in sectors that offer the greatest opportunity to reduce emissions, and where there are fewest options to decarbonise through alternative low carbon technologies.
