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.

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 (http://www.thevale.com.au), 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 (https://tasmaniansolar.com.au).

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.

WA stockfeed company installs 600 kWh Redflow Large Scale Battery to slash energy costs

WA stockfeed supply company Semini Custom Feeds has ordered a 60-battery Large Scale Battery (LSB) – Australia’s largest Redflow-based energy storage system – to cut its fuel and energy costs by 80 per cent.

Working with Redflow’s WA partner, TIEC Electrical, Semini Custom Feeds expects the 600 kilowatt-hours (kWh) system to cut its costs by about $120,000 per year based on current expenditure on diesel, maintenance and mains power.

The Redflow LSB is a powerful integrated system for deploying as many as 60 Redflow zinc-bromine flow batteries in large energy storage systems, delivering as much as 600kWh of energy storage capacity and comprehensive redundancy capabilities.

Once the Redflow LSB and 400 kilowatts-peak (kWp) photovoltaic (PV) solar panel system is deployed, the family-owned business, located at Cowaramup, 260km south-east of Perth, near Margaret River, will also eliminate its need to buy electricity from the grid. The design aims to mitigate 80 per cent of the diesel and servicing costs and all costs for grid-connected services.

The Semini Custom Feeds order is the latest success for TIEC Electrical and Redflow in the WA agricultural sector. Last year, TIEC installed Redflow batteries at multiple rural sites including a WA orchard that has beaten bushfire blackouts and a rural “dream home” that has saved more than $100,000 by not connecting to the electricity grid.
