Ameresco’s portfolio includes energy efficiency, infrastructure upgrades, asset sustainability, and renewable energy solutions delivered to clients throughout North America and Europe. The company’s renewable energy assets and customer projects have delivered a carbon emission reduction equivalent to 95+ million metric tons of carbon dioxide since 2010.

Redflow’s non-lithium energy storage system will be used by Ameresco for medium- to long-duration deployments and daily cycling applications in its integrated cleantech solution portfolio. 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.

Redflow Chief Executive Officer and Managing Director, Tim Harris said, “It is an honor for Redflow to partner with Ameresco as they look beyond conventional lithium technologies. Our zinc-bromine flow battery offers a non-lithium solution that is fire-safe, has an innovative hibernation feature, and suits a wide range of environments and use cases.”

“Additionally, we hope our partnering with Ameresco will initiate other exciting opportunities for our business pipeline and, over time, new markets globally,” said Mr. Harris.

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. Redflow’s 4-battery enclosure is a compact yet scalable energy storage solution for smaller commercial and industrial customers.

“We’re excited to partner with Redflow and leverage their commercial track record to globally deploy non-lithium energy storage systems,” said Doran Hole, EVP and Chief Financial Officer, Ameresco. “This aligns with our relentless pursuit of best-fit solutions for our customers, both in project design and technology fit. The demand for longer-duration energy storage is a critical and rapidly growing market opportunity that can unlock our customers’ ability to cost-effectively meet an increasing amount of their energy needs through renewable sources.”
