Redflow selects TRUMPF electronics to deliver scalable high-voltage grid-level energy storage deployments

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.

Redflow Pod Z scalable module with integrated bi-directional converters from TRUMPF Hüttinger

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.

Redflow enters a high-capacity, high-voltage, grid-scale future with Energy Pod Z energy storage modules

Redflow has today released a YouTube video introducing its new Energy Pod Z energy storage module, which provides access for the company to a high-voltage, high-capacity, grid-scale future

Each Redflow Energy Pod Z module, which integrates 16 Redflow batteries with world-leading power conversion technology, can deliver high-voltage energy and can scale as large as required.

In the video, Redflow Managing Director and CEO Tim Harris and Redflow’s System Integration Architect, Simon Hackett – also the company’s largest shareholder – explain the benefits of the new Energy Pod Z, which was designed to provide two megawatt-hours (2MWh) of energy storage for the Anaergia Rialto Bioenergy Facility in southern California.

“We’re seeing here the start of the high-voltage, high-capacity, grid-scale future for Redflow,” said Simon “This is a great design, this is the first instance of it. We’ve got a pod that has got 16 of our batteries and a set of advanced electronics that take that system, take that battery voltage, and bring it up to the high voltage that’s needed for grid-scale applications.

“Normally our batteries are 48-volt batteries. What we’re adding here is some technology from a great European company that makes power electronics that’s suited to flow batteries, that’s suited for our applications, that turns that low voltage into 800-900 volts.

“The point of doing that is when you want to deploy many megawatts of power, when you don’t just have a few batteries – you want hundreds of batteries, ultimately thousands of batteries – you need to do that at high voltage. 

“So this is the key for us. Once you have this thing in the field, you can essentially have as many as you like…once you run this sort of advanced high-voltage system, the sky’s the limit.”

Tim explains that the Anaergia project is more than Redflow’s largest battery order: “It’s really the foundation for us to go into large megawatt-hour systems,” he said.

Simon Hackett deploys 280kWh Redflow-based rural microgrid at his farm in northwest Tasmania

Redflow’s largest shareholder Simon Hackett has successfully deployed a Redflow-based rural microgrid that delivers energy independence for buildings and equipment on his family farm in northwest Tasmania.

The Vale (, a working sheep farm with the largest private runway in Tasmania, is a 73-hectare property including a number of farm buildings and multiple houses.

The Vale’s 100 kilowatt-peak (kWp) solar array and 28-battery Redflow-based energy storage system caps an extensive design, development and deployment project undertaken during the past year by DMS Energy of Spreyton, Tasmania (

Simon, who leads Redflow’s software and integration efforts as its Systems Integration Architect, said the system would eliminate grid electricity costs for the property. “The system also gives us energy resilience by automatically switching to off-grid mode during any grid power failures,” he said.

Why it’s not all about lithium batteries

Redflow CEO Tim Harris recently briefed Eureka Report’s Alan Kohler about the company’s achievements to date including its recent breakthrough sale to Anaergia in the US.

In the 35-minute interview linked and transcribed below, Tim explains to Alan how zinc-bromine flow batteries are uniquely suited to specific energy storage applications, such as storing power at hot and remote locations such as mobile phone towers in rural areas.

Redflow signs its largest global battery sale with Anaergia to supply energy storage in California

Australian energy storage company Redflow Ltd (ASX: RFX) has signed an agreement to supply a 2 MWh energy storage system comprising of 192 zinc-bromine flow batteries to Anaergia, Inc. (Anaergia), a global technology leader in recovering value from waste.

The batteries will support two-megawatt hours (MWh) of energy and reduce peak energy use at Anaergia’s Rialto Bioenergy Facility (Facility) as part of the Facility’s microgrid. The Facility is located in San Bernardino County, California, and owned by Rialto Bioenergy Facility, LLC, an Anaergia company.

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-fueled cogeneration unit, and a microgrid control system.

This agreement represents Redflow’s largest single sale and deployment of batteries globally.

“Anaergia selected Redflow’s zinc-bromine flow batteries because they are uniquely suited to meet the demands of the Rialto site,” said Yaniv Scherson, Anaergia Chief Operating Officer.

Once fully operational, the Facility will be North America’s largest landfill diverted organic waste digester facility. The Facility will convert 700 tonnes per day of organic waste and 300 tonnes per day of biosolids into renewable natural gas and Class A fertilizer. The Facility is located 80 kilometres (50 miles) east of Los Angeles and services the organic waste recycling needs of Los Angeles and the Southern California region.

Redflow commences first customer trial of new Gen3 battery

Redflow Limited (ASX: RFX) is pleased to announce the commencement of the first customer trial of its new Gen3 battery.    

Using two new Gen3 batteries, the trial will take place in Mount Tamborine in Queensland where Redflow already has four Gen 2 batteries supporting an off-grid energy system with end customer James Emmett.  The two new Gen 3 batteries at the Mount Tamborine site will run for a number of weeks before returning to Redflow for further analysis and testing. 

Commenting on the deployment, Redflow CEO and Managing Director Tim Harris said: “This is an important development milestone for Redflow’s Gen3 battery to become customer and production ready in 2021.  Having previously outlined our goal to commence customer trials of the Gen 3 battery by the end of 2020, we are pleased that the Gen 3 battery development and program is on track.  There is no substitute for real-life customer testing and this trial will be very valuable to understand how the Gen3 battery performs in a live environment.” 

“With Gen3, we are confident of achieving a 30% reduction in manufacturing costs through supply chain and engineering productivity impacts.  We also believe further savings can be targeted through further production and scale benefits.  The Gen3 battery will underpin Redflow’s ability to expand into larger systems and more rapidly increase take-up of our world-leading Australian technology.”
