About Redflow

Redflow Limited, a publicly-listed Australian company (ASX: RFX), produces small 10kWh zinc-bromine flow batteries that tolerate daily hard work in harsh conditions. Redflow batteries are designed for high cycle-rate, long time-base stationary energy storage applications in the telecommunications, commercial & industrial and high-end residential sectors, and are scalable from a single battery installation through to grid-scale deployments. Redflow batteries are sold, installed and maintained by an international network of energy system integrators. Redflow’s smart, self-protecting batteries offer unique advantages including secure remote management, 100 per cent daily depth of discharge, tolerance of high ambient temperatures, a simple recycling path, no propensity for thermal runaway and sustained energy delivery throughout their operating life.

Underwriters Laboratories Inc. has selected Redflow ZBM batteries to carry out research to characterize the operating and safety profile of redox flow batteries under nominal and off-nominal conditions. 

The Electrochemical Safety Research Institute at Underwriters Laboratories has undertaken the test program in collaboration with Stress Engineering Services Inc. (SES) and Redflow to understand key technical attributes of redox flow batteries, study their cycle life and aging properties and to understand how the batteries behave under off-nominal conditions of overcharge, over-discharge and external short-circuit conditions. Six Redflow batteries were purchased by Underwriters Laboratories in 2021 and arrived at the SES facility in Texas in December. The test program commenced in January 2022 and will run for a number of months.

“We are delighted to be working with industry leaders Underwriters Laboratories and SES to verify the performance and safety characteristics of flow battery storage using our Redflow batteries,” said Tim Harris, managing director and CEO of Redflow. “Redflow’s CTO Steve Hickey and I were able to meet the Underwriters Laboratories and SES teams at their Texas facility last month to advise on the setup of the Redflow batteries and provide broader input on the test program.”

Redflow Energy Pods deployed at Anaergia’s Rialto Bioenergy Facility in CaliforniaRedflow Energy Pods deployed at Anaergia’s Rialto Bioenergy Facility in California

Redflow completes the 2 MWh energy storage system for Anaergia in California.

The 2 MWh sale was announced on March 9, 2021 and represents Redflow’s largest single sale of batteries to date.

The energy storage system, comprising 192 zinc-bromine flow batteries, is designed to store up to two megawatt hours (MWh) of energy and reduce peak energy use at Anaergia’s Rialto Bioenergy Facility as part of the Facility’s microgrid. The microgrid project was funded in part by a grant from the California Energy Commission and consists of the batteries, a biogas conditioning system to support a 2.0MW biogas-fuelled cogeneration unit, and a microgrid control system. The battery system is comprised of 12 x 160 kWh Redflow Energy Pods which are clustered into four strings tied to four 125 kW Dynapower inverters.

  • IZA members represent 60 per cent of worldwide zinc production and 80 per cent of Western Hemisphere production
  • IZA’s Zinc Battery Initiative aims to promote Zinc batteries’ substantial advantages over competing chemistries such as lithium-ion and lead-acid, especially in Redflow's focus of long-duration energy storage
  • Joining the IZA and Zinc Battery Initiative benefits Redflow’s focus on developing the market for zinc-bromine flow batteries in North America and other core markets.

Australian energy storage company Redflow Limited today announces that it has joined the International Zinc Association (IZA) to contribute to a global initiative promoting the benefits of zinc-based energy storage.

The International Zinc Association is a Group whose members represent 60 per cent of worldwide production of zinc and 80 per cent of production in the Western Hemisphere. In addition, it has more than 150 affiliate members from key zinc-consuming end-user groups.
