Ameresco & Redflow agree battery storage deal

US renewable energy company Ameresco and energy storage company Redflow Limited have entered a “strategic relationship” through which Redflow will supply Ameresco, on a non-exclusive basis, with its non-lithium battery energy storage technology. 

Redflow’s energy storage system will be used by Ameresco for medium to long-duration deployments and “daily cycling applications in its integrated cleantech portfolio”, a statement said.

It added that Ameresco plans to deploy Redflow’s zinc-bromine flow batteries as part of a “flexible and modular integrated solar and storage solution, which is being designed to meet the increasing need in the market for medium and long-duration systems”.

Currently, Redflow and Ameresco are working to deploy a commercial demonstration system incorporating Redflow’s 40 kWh 4-battery enclosure to one of Ameresco’s existing customer sites.
