CumulusEnergyStorage

Cumulus Energy Storage is a leading brand that specializes in manufacturing and developing grid-level energy storage batteries with the lowest levelised cost of storage (LCOS) globally. In an era where renewable electricity is becoming increasingly important, Cumulus aims to provide large-scale storage solutions that enable industry to have instant access to renewable electricity, ensure the grid's capacity for secure supply, and facilitate time-shifting for renewables like solar energy after sunset. The need for energy storage is backed by legislation, as the growth in distributed renewable generation, especially solar PV, creates challenges for grid infrastructure and incumbent generators worldwide.

Cumulus has pioneered a groundbreaking approach by combining a 200-year-old battery technology with industrial-scale mining and water treatment processes. The result is the creation of a patent-granted, low-cost grid-scale rechargeable Copper/Zinc battery. With the backing of the UK government and equity investment, Cumulus plans to establish pilot line production and subsequently expand into full production capacity.

By partnering with global component manufacturers and forming and assembly plants at a continental level, Cumulus aims to provide super-storage products and services to customers through local project developers.
