Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what representations he has received on the development of compressed air energy storage.

The Secretary of State has received correspondence from stakeholders across the energy sector on electricity storage technologies, including Compressed Air Energy Storage (CAES). Details of Ministers' and Permanent Secretaries' meetings with external individuals and organisations are published quarterly in arrears on GOV.UK. This government introduced a Long Duration Electricity Storage (LDES) Cap and Floor investment support scheme as part of our clean energy superpower mission. The scheme is being delivered by Ofgem and CAES projects, as well as many other LDES technology projects, have applied, details of which can be found on the Ofgem website.
