Whitepaper: Redflow ZBM and telecommunications integration

This article reports about the successful demonstration of Redflow’s unique zinc-bromine flow batteries integrated into a standard telecommunication (Telco) DC system at -48V.  Redflow ZBM2s, installed directly on the DC bus, can replace standard lead acid batteries and support the load when the power from the grid or from a diesel generator (DG) is not available. In this specific study, Redflow’s first generation ZBM batteries are used to integrate renewable sources (PV) with an existing DG allowing the coexistence of multiple sources, absorbing the load and PV fluctuations and most importantly reducing the DG run time. The DG is simulated using the grid supply. This also demonstrates the excellent response of the ZBM in brown sites (where there is no reliable grid support). To learn more, download Redflow’s telecommunications white paper.

Whitepaper: Understanding the Redflow Battery

Flow batteries are a well-understood class of energy storage device. Before Redflow, commercial flow batteries were too large, in terms of both physical size, storage capacity, for common commercial and residential energy storage applications.
Redflow has successfully designed and commercialised a small, modular, flow battery based on zinc-bromine reactants and referred as ZBM (Zinc Bromide Module). Redflow’s ZBM2 zinc-bromine flow battery has proved versatile and successful for a range of energy storage applications.

In this white paper, Redflow’s world-leading zinc-bromine flow battery technology is described to highlight flow battery advantages, resilience and robustness. After introducing the battery, its underlying composition is discussed. Key advantages of this technology are listed, along with the design choices that made the ZBMd a reliable and robust battery. The white paper also broadly addresses the topic of ZBM2 installation and integration. Specific application notes and design guidelines can be found on the Redflow website.

Case Study: Redflow Smart Grid Smart Cities Trial

NEWINGTON, NSW, AUSTRALIA, 2012: The Australian Government has chosen Ausgrid to lead a $100 million initiative across five sites in Newcastle, Sydney and the Upper Hunter regions (see Figure 1). Smart Grid, Smart City creates a testing ground for new energy supply technologies. At least 30,000 households will participate in the project over three years. The demonstration project gathers information about the benefits and costs of different smart grid technologies in an Australian setting. Building a smart grid involves transforming the traditional electricity network by adding a chain of new, smart technology. It includes smart sensors, new back-end IT systems, smart meters and a communications network.

Demonstration trial partner – AusGrid

Ausgrid and the Australian Government


Ausgrid is a major utility in New South Wales Australia.  In conjunction with the Australian Government’s Smart Grid, Smart City trial, Redflow installed sixty R510 residential energy storage units in Newcastle and the Hunter Valley as part of the Australian Government’s Smart Grid, Smart City project.  Redflow’s involvement with this part of the project extended from late 2011 to mid-2013.  Another R510 was also installed as part of the Newington Smart Home sub-project.  Redflow began its involvement with this trial in 2010 with a lead-acid energy storage system, after which the system was upgraded to an R510 in late 2011 before ending its time at the Smart Home in mid-2013.  Please see the Smart Grid, Smart Cities R510 Case Study for more information regarding Redflow’s experience with Australian utility, Ausgrid, of the design, installation and operation of 61 R510 electricity storage systems in New South Wales, Australia. Redflow’s Whitepaper also provides an overview of key results and lessons learnt from the project.

Demonstration trial partner – Ergon Energy

Ergon Energy Corporation

Ergon Energy

Ergon Energy is the Queensland Government-owned electricity distributor to regional Queensland, with an asset base of $8 billion and more than 650,000 residential and business customers. RedFlow supplied 30 ZBM systems for installation and integration within the Ergon Energy electricity supply network, as part of the Australian Government’s Advanced Electricity Storage Technologies (AEST) program. The systems were used for managing peak electricity demand within three locations in Ergon Energy’s rural network and were remotely monitored by both RedFlow and Ergon Energy.
