Energy storage is an essential element to balance the UK grid

Energy storage systems store energy generated by solar and wind. CX Energy was one of the first companies to enter the battery storage market, and we remain a pivotal player in this arena.

We try to reuse repurposed electric vehicle (EV) batteries, particularly from Volvo electric buses, trucks and machines, providing significant environmental and economic benefits.

We offer a full turnkey solution from design, build and connections to the distribution network operator (DNO). We have been involved in installing 500 MW of energy storage, including co-location with active solar farms.

The benefits of energy storage

Reduces carbon footprint compared to new batteries

Utilises repurposed batteries with up to 80% of original capacity

Helps manage peak load spikes and grid capacity constraints

Avoids costly grid upgrades

Supports EV charging with decarbonisation

Energy storage FAQs

Solid-state batteries and improvements in lithium ion technology are increasing storage capacity.

Rapid growth is expected, with UK battery storage capacity projected to increase from 2.1 GW to 24 GW by 2030.

Repurposed EV batteries can last for an additional 7–10 years in stationary storage applications. This will depend on usage patterns and maintenance.

Co-locating storage with solar farms allows excess solar energy to be stored and used during peak demand, improving energy availability and reducing the reliance on fossil fuels.

Energy storage enables better integration of renewable sources by storing surplus energy when production exceeds demand. It is typically released during peak times to support grid stability and helps to reduce the reliance on fossil fuels.
