Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what steps her Department is taking to accelerate the use of (a) battery storage and (b) other energy storage installations to store renewable energy on the grid when it cannot accept it due to capacity constraints.

The Government is facilitating the deployment of electricity storage, including battery storage, through actions set out in the 2021 Smart Systems and Flexibility Plan.

On longer duration electricity storage, the Government has committed to developing an appropriate policy framework by 2024 to enable investment and deploy sufficient storage to balance the system. The Department is planning to consult on the framework this year.

On hydrogen storage, the Government has set out its preferred hydrogen storage business model to unlock private sector investment and remove barriers. The Government has secured amendments to the Energy Bill to introduce the primary powers to deliver this business model by 2025.
