Long-duration energy storage developer ESS Inc is partnering with Energy Storage Industries Asia Pacific to distribute and manufacture 12GWh of iron flow batteries in Australia, New Zealand and Oceania.
In the next 16 months, ESS will supply 70, 75kW/500kWh Energy Warehouse systems to ESI who will build a manufacturing facility in Queensland, Australia equipped to conduct final assembly of the ESS systems from 2024 onward.
Systems manufactured at the Queensland facility will use “core component kits” supplied by ESS including battery modules, proton pumps, and other components.
The core component kits are to be manufactured in Oregon, US.
The ESI manufacturing facility is designed to reach a production capacity of up to 400MW of energy storage annually.
Stuart Parry, managing director of ESI, said iron flow batteries were perfect for Australia’s harsh environment and the ability to locally source electrolyte provided insurance against supply chain risks and price escalation.
ESS iron flow technology provides long-duration energy storage and is ideal for applications that require 4-12 hours of flexible energy capacity, including: utility-scale renewable energy installations, remote solar + storage microgrids, grid load-shifting and peak shaving, and other ancillary grid services.
New South Wales announced the procurement of 2GW of long-duration energy storage systems in its Electricity Infrastructure Roadmap.
