£300m energy storage plant 'could make Greater Manchester a leader in the net zero transition'

The backers of a pioneering £300m energy storage plant set for Greater Manchester say it could play a key role in the º£½ÇÊÓÆµ’s net zero transition.

Highview Power has announced it has secured investment from energy giant Centrica and the º£½ÇÊÓÆµ Infrastructure Bank to build the first commercial-scale liquid air energy storage (LAES) plant in the º£½ÇÊÓÆµ. The consortium says work on the scheme will start immediately with the aim of completing it by early 2026, and says the scheme could support 700 jobs in construction and the supply chain while under construction.

The £300m funding package includes investment from mining and metals giant Rio Tinto, investment group Goldman Sachs, Danish fund KIRKBI, and Mosaic Capital.

The plant will be used to store excess energy generated by wind turbines, and then can release it when needed and when the turbines are not spinning.

The plant uses that energy to chill and liquefy air before storing it in insulated tanks. When power is needed, the air is heated and expanded and the resulting high pressure gas drives a turbine to generate energy that can be sent out of the plant again. No fuel is burned during the process.

Highview says its plant can store energy for longer than current batteries could. It plans to develop a network of storage plants across the º£½ÇÊÓÆµ, starting in Carrington,to provide a stable supply of green energy to the National Grid.
