Redflow Limited, a publicly-listed Australian company (ASX: RFX), produces small 10kWh zinc-bromine flow batteries that tolerate daily hard work in harsh conditions. Marketed as ZCell and ZBM2, Redflow batteries are designed for high cycle-rate, long time-base stationary energy storage applications in the residential, commercial & industrial and telecommunications 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.

 

Redflow CEO Tim HarrisAustralian energy storage company Redflow Limited (ASX: RFX) today has announced an order to provide six ZBM2 zinc-bromine flow batteries for energy storage at an Optus mobile phone tower in the environmentally sensitive Daintree rainforest.

The Redflow ZBM2 batteries will store and supply 60 kilowatt-hours (kWh) of energy for the Optus mobile phone tower at Alexandra Range, in the Cape Tribulation section of the Daintree rainforest, a remote headland and ecotourism destination in Far North Queensland. Situated 1500km north of Brisbane, the Daintree National Park became a World Heritage Site in 1988.

Optus selected Redflow’s ZBM2 batteries for deployment at their Cape Tribulation site because of the batteries’ sustained energy storage capacity, tolerance of warm temperatures, remote management capability and environmentally-friendly design. 

Redflow CEO Tim HarrisAustralian energy storage company Redflow Limited (ASX: RFX) has signed an agreement to supply 32 zinc-bromine flow batteries for two new state-of-the-art children’s centres in Melbourne’s eastern suburbs.

The Knox Children and Family Centres at Wantirna South (due to open in January 2019) and Bayswater (due to open in March 2019) will each include 100 kilowatts of photovoltaic solar panels and 16 Redflow ZBM2 batteries, storing as much as 160 kilowatt-hours of energy.  Renewable energy with Redflow storage is expected to generate annual energy cost savings of $140,000 for each site.

The advantages of Redflow’s zinc-bromine flow batteries include:

  • The ability to discharge 100 per cent of their stored energy daily without damaging the battery
  • Sustained energy storage capacity for 10 years
  • Tolerance of warm temperatures, and
  • Inherent safety with a non-flammable electrolyte.

Redflow partner Torus Group, which is installing both solar panels and batteries, will install the first ZBM2 zinc-bromine flow batteries next week.

Redflow CEO Tim HarrisRedflow CEO Tim HarrisAustralian energy storage company Redflow Limited has received an order to supply five zinc-bromine flow batteries for a pilot project to provide standby energy storage for mobile phone towers in South Africa.

This order will see Redflow provide the project with batteries for five identified sites with the first batteries to be deployed in November. The project will see Redflow’s zinc-bromine flow batteries provide energy storage for the mobile phone towers, operated by one of South Africa’s leading telcos. The towers will be owned by a local company, supported by the South African Government’s Black Economic Empowerment (BEE) affirmative action agenda.

The sale was made through Redflow’s long-term South African partner, Specialized Solar Systems (SSS), which has formed a joint venture company with specialist telco supplier Amber Energy. Called SSS Gauteng, the new company will deliver the energy storage and telecommunications skills to deploy the batteries on remote mobile phone towers.

Redflow has worked with SSS to enable its batteries to operate in Standby Power System (SPS) mode. In this newly created operating mode, Redflow batteries can be charged and then placed in a dormant state, with no self-discharge, until a power outage. When energy is required, the battery can boot up to full operational status in a similar timeframe to a standby generator – with no internal combustion engine and no fuel storage required on the site.

Redflow Managing Director and CEO Tim Harris said this sale created a significant opportunity for the company. “The Standby Power System, which Redflow has developed with our partners, will help open the door for access to other cellphone network operators in Africa and internationally,” he said.
