Cumulus Energy Storage, one of the UK’s most promising cleantech SMEs, has obtained seed funding after attending Missions run by Innovate UK and the Department for International Trade.

Cumulus uses technology similar to that already used in the mining industry, to produce a rechargeable Copper/Zinc battery that is safe, reliable and sustainable. The process allows this to be used as a re-chargeable grid-storage battery, using inexpensive, recyclable materials.

In 2014, Cumulus set up a research and development facility in San Francisco, California, using lab facilities to develop full-scale prototypes that were grid connected. California is the first state to mandate energy storage, with a target of 1.3GW of energy storage by 2020.

In August 2016, having grown to a team of 6 in Rotherham and 10 in San Francisco, Cumulus moved into a new 800 sq.ft. office space at the Technology Centre where it is now preparing a development line capacity of 1MWh/year and plans to move into a 26,000 sq.ft. facility at the Advanced Manufacturing Park to facilitate this in 2017.
