What is battery box?

Enter Battery Box: a local energy storage solution that helps manage the timing differences between intermittent energy generation and electricity usage.

How will UK energy storage demonstration projects help achieve net zero?

The four longer-duration energy storage demonstration projects will help to achieve the UK’s plan for net zero by balancing the intermittency of renewable energy, creating more options for sustainable, low-cost energy storage in the UK.

Can electricity be stored in EDF's existing gas storage facilities?

The final project will explore how electricity, converted into compressed air, can be stored in EDF’s existing gas storage facilities, where EDF Thermal Generation and R&D will partner with io consulting and Hydrostor.

Why do we need a battery box?

By maximising UK renewable energy sources, we can reduce reliance on imported oil and gas. Renewable energy stored in Battery Boxes will be used to support local businesses, communities and organisations and reduce the risk of localised power cuts.

How will energy be stored?

Energy will be stored as compressed air in the underground cavities at times of surplus, and then released when required to meet system demand – in a low carbon manner and while providing other system benefits, such as grid stability and flexibility services.

How does a battery box work?

Each Battery Box connects directly into the local electricity network, the same network that supplies homes, businesses, schools, and hospitals. Battery Boxes charge when the cost of electricity is low, which is normally on windy or sunny days when we have excess renewable power, or overnight when the demand for power is low.
