Energy storage innovator Redflow has taken a significant step towards local manufacturing through a Memorandum of Understanding (MoU) with Queensland’s Stanwell Corporation.

Redflow and Stanwell will collaborate on the development and deployment of Redflow’s new X10 battery solution for use in a large-scale project of up to 400MWh, which will serve as a potential anchor order for Redflow’s planned manufacturing facility in Queensland.

The federal government has highlighted zinc-bromine flow batteries as one of a handful of battery technologies that are cheaper to scale, have long cycle-life and are specifically relevant for large-scale systems.

Stanwell and Redflow will undertake a preliminary due diligence pre-feasibility study for an initial 5MWh project using Redflow’s new X10 battery at the Stanwell Future Energy Innovation Training Hub (FEITH) near Rockhampton, Queensland.

The MoU and proposed projects with Redflow form part of Stanwell’s strategy to develop alternative technologies and build a renewables portfolio including 9-10GW of generation and 5GW of storage by 2035 to support the Queensland Government’s renewable energy targets.

Redflow CEO and managing director Tim Harris said, “Stanwell is a leader in developing renewable energy solutions to accelerate Queensland’s energy transition and we are excited to be partnering with them on these studies and pilot project to further advance our new X10 product.

“With the launch of the Queensland Government’s Battery Strategy and Energy and Jobs plan, and the recently released Australian Government National Battery Strategy, this announcement reinforces the incredibly critical role that energy storage and more specifically long-duration energy storage, will play in Australia becoming a renewable energy superpower.”

Stanwell CEO Michael O’Rourke said, “Stanwell has ambitious targets for energy storage within our portfolio, and we see longer duration energy storage solutions such as Redflow’s as being crucial to meeting our customer demand for firmed renewable solutions.

“We already have a number of battery storage projects in the pipeline, and this new partnership will ensure the battery technologies deployed in the future are the best fit to serve our communities and customers through our renewable transformation.

“We are looking forward to working with Redflow to develop the roll out of their new X10 solution at Stanwell’s Future Energy Innovation and Training Hub”.

The feasibility study is scheduled to be completed in early 2025 followed by a decision to proceed with the 5MWh X10 battery project, which is expected to be deployed in the first half of 2026.
