Redflow Limited, a publicly-listed Australian company (ASX: RFX), produces small 10kWh zinc-bromine flow batteries that tolerate daily hard work in harsh conditions. Marketed as ZCell and ZBM2, Redflow batteries are designed for high cycle-rate, long time-base stationary energy storage applications in the residential, commercial & industrial and telecommunications 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.
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.
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.
Australian energy storage company Redflow Limited has integrated bi-directional converters from global electronics manufacturer TRUMPF Hüttinger into its innovative Energy Pod Z scalable modules to deliver large-scale energy storage for major projects.
The first deployment of Redflow’s new Energy Pod Z grid-scale modular architecture is for a two megawatt-hour energy storage system at a major US bioenergy facility for a global technology leader in recovering value from waste. The project in southern California marks Redflow’s first major project in the US and its largest global deployment to date.
Each Pod-Z module contains 16 Redflow batteries integrated with TRUMPF Hüttinger TruConvert bi-directional DC voltage converter/controllers. This integration allows the pods to deliver energy in the 700–900-volt DC range that is needed to construct and operate truly grid-scale energy system deployments.
By using TRUMPF Hüttinger power conversion modules to configure each of the 12 pods for a 50kW high voltage energy throughput, the total system at the California facility will achieve a continuous energy rating of 600kW. The Energy Pod Z architecture using TRUMPF DC converters has no limit on the number of Energy Pod Z modules that can be deployed, enabling the architecture to support much larger energy storage sites.
