Redflow aims to qualify its batteries for State-based adoption programs

Redflow is working with relevant authorities to identify paths that will enable Australians to buy our zinc-bromine flow batteries with the support of State-based home battery incentive programs.

These programs, designed to encourage the uptake of home-based energy storage, includes South Australia’s Home Battery Scheme and the Queensland Government’s Solar Battery rebate.

The obstacle is that inclusion of energy storage systems in these programs is linked to conformance with a battery Best Practice Guide developed by a number of government and industry bodies and managed by the Clean Energy Council (CEC).

This guide was developed specifically to address and reduce the safety hazards posed by lithium-based battery chemistries; notably their potential fire risk due to the volatility of the materials in these batteries.

The unintended consequence of these programs accepting only batteries listed in this Best Practice Guide is the exclusion of energy storage systems such as those from Redflow which do not contain lithium and thus do not experience the hazards associated with lithium batteries.

Redflow’s zinc-bromine flow battery chemistry offers safety advantages over traditional battery chemistries, including substantially lower fire risk: Indeed, the bromine in Redflow’s electrolyte is a substance that is widely used as a fire retardant.

As a proudly Australian energy storage technology company that has invested many millions of dollars in research and development during the past 10 years, it is frustrating to see multinational batteries benefit from taxpayer-funded incentive programs that exclude Australian-designed batteries.

Redflow recognises that safety is always the first priority in such initiatives, so we welcome full scrutiny of our battery’s safety record, evaluation of any risks and how they are mitigated.

Redflow is working with various industry organisations and State Government agencies to identify any path that will enable Australian consumers to buy a Redflow battery via State Government-supported battery incentive programs. We will keep you posted on progress as it occurs.

Redflow on growth trajectory after emerging from a two-year turnaround

Redflow batteries supply energy for remote Thai village

Redflow ZBM2 zinc-bromine flow batteries are now storing solar energy to provide a reliable power supply for a remote village in mountainous northern Thailand that has long lacked electricity.

In a project backed by the Thai Government, the village of Ban Pha Dan in Lamphun province is using solar cells to harvest energy and a high-performance hybrid battery system, including ZBM2s, to store energy for a village microgrid that is separated from the national electricity distribution network.

Ban Pha Dan, 70km south of the northern Thai city of Chiang Mai, is a small village that has lacked access to electricity because it is surrounded by a wildlife reserve where power poles are forbidden. This microgrid project was initiated by Thailand’s Energy Ministry and the Renewable Energy for Sustainable Association with financial support from the Energy Conservation Promotion Fund.

Redflow wins second South African telco battery sale

Australian energy storage company Redflow Limited (ASX: RFX) has won a follow-up sale of 32 zinc-bromine flow batteries to provide standby energy storage for mobile phone towers in South Africa.

This second sale follows an initial order last month for five batteries for use at mobile phone towers run by a leading South African telecommunication company. The towers are owned by a local company that is supported by the South African Government’s Black Economic Empowerment (BEE) affirmative action agenda.

Redflow CEO Tim Harris, who received the new order after a visit to South Africa last week, said it clearly demonstrated the technological and commercial viability of Redflow’s zinc-bromine flow batteries for telecommunication deployments. “Our batteries thrive on heat and hard work, which is what these sites in South Africa require.  Following yesterday’s Optus announcement, today’s new sale further highlights the value proposition that Redflow’s ZBM2 zinc-bromine flow batteries deliver to telecommunications companies, both in Australia and overseas,” he said.

Redflow batteries to power Optus mobile tower in Daintree rainforest

Redflow 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 batteries to store renewable energy for new children’s centres in Melbourne’s east

Redflow is pleased to announce that it has signed an agreement to supply 32 of its 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. Continue reading “Redflow batteries to store renewable energy for new children’s centres in Melbourne’s east”

Redflow supplies batteries for South African mobile phone towers

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.
