Redflow Reports Largest Sale of ZBM2 Batteries to Power Hybrid Energy Storage Systems in the Tropics

09 May 2017

Australian energy storage specialist Redflow announces its largest single sale of ZBM2 zinc-bromine flow batteries, worth about US$600,000 (A$800,000), for multiple sites in the Pacific Islands.

Redflow partner Vertiv (formerly Emerson Network Power) will provide the batteries for an energy storage solution being designed by New Zealand-based Hitech Solutions.

Hitech is building advanced hybrid energy storage systems to provide reliable, remote power to multiple sites in a Pacific Island nation. This first ZBM2 order from Hitech supports the first stage of a multiple stage project.

Redflow CEO Simon Hackett said this major sector sale recognised the unique advantages of its batteries. “This high-workload deployment in the tropics is ideal for our zinc-bromine flow batteries,” he said.

“Redflow’s ZBM2 is the world’s smallest flow battery – uniquely qualifying it to replace lead-acid batteries in remote site deployments, such as telecommunication sites. The ZBM2 runs natively at 48 volts DC, making it simple to install. It is also easy to deploy in scalable parallel clusters for high availability, high scale deployments at the largest sites.

“The ZBM2 excels in hot environments, such as the tropics, for applications that require high cycle depth and cycle frequency, as in the deployment Hitech is planning. This sort of environment and application cycle kills lead-acid batteries in fairly short order, requiring their frequent replacement, whereas our batteries thrive on heat and hard work.”

Auckland-based Hitech Solutions specialises in providing telecommunications and infrastructure services for clients in New Zealand and internationally.

Hitech Solutions Chief Operations Officer Derek Gaeth said the company had chosen Redflow batteries as the best fit for purpose in this specific use case. “Redflow’s zinc-bromine flow batteries were our best choice because they meet the needs of this project,” he said.

“ZBM2 batteries are well suited to managing hybrid power, have a good charge/discharge profile and have a high tolerance of temperature variance, especially heat, which is important in the tropics.”

Vertiv is a mature Redflow system integrator that has previously deployed ZBM2 batteries for telco-related energy storage systems in New Zealand and Australia.

Vertiv Managing Director Australia/New Zealand Robert Linsdell said this order for Redflow’s zinc-bromine flow batteries supported Vertiv’s remote and black spot strategy for telecom. “Redflow is a smart Australian company that has developed a world-leading energy storage solution that we’re happy to offer,” he said. “Hitech is creating an environmentally sustainable solution that combines solar energy with the environmentally friendly ZBM2 battery.”
