About Redflow

Redflow Limited, a publicly-listed Australian company (ASX: RFX), produces small 10kWh zinc-bromine flow batteries that tolerate daily hard work in harsh conditions. Redflow batteries are designed for high cycle-rate, long time-base stationary energy storage applications in the telecommunications, commercial & industrial and high-end residential sectors, and are scalable from a single battery installation through to grid-scale deployments. Redflow batteries are sold, installed and maintained by an international network of energy system integrators. Redflow’s smart, self-protecting batteries offer unique advantages including secure remote management, 100 per cent daily depth of discharge, tolerance of high ambient temperatures, a simple recycling path, no propensity for thermal runaway and sustained energy delivery throughout their operating life.

Hitech Solutions Chief Technology Officer Derek GaethAustralian energy storage company Redflow Limited has shipped zinc-bromine flow batteries made at its new factory in Thailand to fulfil its largest-ever order for use in a digital television network in Fiji.

New Zealand-based telecommunications infrastructure specialist Hitech Solutions last year chose Redflow’s ZBM2 batteries to provide energy storage for Fiji’s new digital television network which it is deploying for the Fiji Government throughout the Pacific nation, including remote islands.

Hitech Solutions ordered US$1.2 million worth of Redflow ZBM2 batteries to store and supply renewable energy to power the Fijian digital TV network. The company, which has operated a five-battery trial site in Fiji during the past year, intends to scale up its deployment of solar panels and Redflow batteries during the next six months. Hitech will install from five to 60 ZBM2 batteries at more than 10 sites in Fiji, many of which are on hills with no access to the country’s electricity grid.

Unveiled in December last year, the digital TV network will provide Fijians, even in the most remote parts of the country, with access to eight free-to-air television channels through a set top box, plus an option for catch-up TV. Digital television will also provide a platform to telecast important messages to people in maritime zones and rural areas in times of disaster, such as cyclones.

Hitech Solutions selected Redflow’s zinc-bromine flow batteries for the challenging project because of their robustness, long life, safety, temperature tolerance and straightforward recycling process. Hitech saved 40 tonnes of battery weight by choosing Redflow batteries over lead-acid batteries - the typical choice for telecommunication network energy storage.

Hitech Solutions Chief Technology Officer Derek Gaeth said Redflow batteries offered many benefits for the Fijian deployment. “The primary need was for a robust design with a long service life,” he said.

Redflow CEO Tim Harris with ZBM2 4 WRedflow CEO Tim Harris with completed ZBM2 batteriesAustralian energy storage company Redflow Ltd last month began manufacturing complete zinc-bromine flow batteries at its new factory in Thailand, which it is now shipping to customers in Australia and internationally.

Redflow reports the factory now has the capacity to consistently produce as many as 90 ZBM2 batteries per month. The company will synchronise production volumes with customer demand.

Redflow CEO Tim Harris said manufacturing complete batteries from the factory marked an important milestone for the company. “This achievement is underpinned by our ongoing focus on ensuring the consistent supply of quality batteries from this new facility,” he said.

YourDC CEO Scott Hicks: "I decided that Redflow was the far superior option "Australian technology entrepreneur Scott Hicks has saved thousands of dollars a year in power costs at his riverside holiday house by adding solar panels and a Redflow ZCell zinc-bromine flow battery.

Mr Hicks, CEO of private data centre provider YourDC, bought the spacious house at Mannum, a Murray River town 84 kilometres east of Adelaide, as an accessible hideaway from the working week. The 10-year-old holiday house is on the banks of the Murray River, among gum trees and wildlife.

However, during his first year, Mr Hicks discovered this peaceful repose came a price - the high cost of electricity. “During the first year, we found that our power bills were huge,” he said. “Our usage peaked at the most expensive time of day because we had lots of air con running.” 

After researching solar panels and energy storage systems, Mr Hicks said Redflow’s ZCell zinc-bromine flow battery stood out. “I decided that Redflow was the far superior option out at Mannum where it’s a couple of degrees warmer than in the Adelaide metro area,” he said.
