Our Heat in Buildings Strategy, which will be published in due course, outlines four key no and low regrets areas strategic technologies for the transition, including energy efficiency, heat pumps in on and off gas grid areas and low and zero emissions heat networks. It also highlights that here may be a small number of buildings for which bioenergy, including HVO among others, may play a role for home heating if displacing fossil fuels in off-gas-grid areas where electric heating or heat pumps are unsuitable.
