Report: The University of Queensland (Australia)

BRISBANE, QLD, AUSTRALIA, 2012: The University of Queensland (UQ) has installed the largest rooftop-mounted solar PV array in Australia (1.2 MW), located on three of its buildings at its flagship St Lucia campus in Brisbane, Australia.

In mid-2012, Redflow has installed its M90 energy storage system (90kW / 240kWh) alongside one section of the UQ solar field, marking our entry into the megawatt-scale class of energy storage systems.  It was designed to store solar power generated from a 390 kW section of UQ’s PV array in the daytime, and feed it back into the local network at times when it is needed most.

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.
