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 effectiveness of sand batteries in tackling climate change.
BEIS has not made any specific assessment of the effectiveness of sand batteries. However, sand batteries form part of a class of technologies known as thermal storage, all of which play a similar role in supporting the changes to the energy system needed to address climate change. These technologies are in an early stage of development and BEIS fund innovation in thermal storage as part of the Longer Duration Energy Storage Demonstration Programme.
