Redflow batteries deliver 24-hour power and save $10,000 in diesel per year for off-grid WA station

Yallalong Station, a 348,000-hectare cattle property 650km north of Perth, has deployed a Redflow battery-based energy storage system to boost its energy independence and save thousands a year in diesel costs.

The cattle station, in the dry Murchison region north east of Geraldton, can swelter for months in summer temperatures higher than 40 degrees Celsius – sometimes as high as 48 degrees Celsius.

Yallalong Station owner Lyndon Brown said a 24-hour power supply was essential to attract staff to work at this remote location. “If you want people to live out there in those isolated places, you do need 24-hour power to run all your fridges, air-conditioning and comforts of life that they expect,” he said.

CEO Video: Redflow’s latest 4C statement shows progress on executing the company’s growth strategy

Redflow CEO and Managing Director Tim Harris provides an update on how the business is performing, in a video released after today’s 4C quarterly cash flow report.

Mr Harris said Redflow had made further progress executing on its growth strategy during Q2.  “Revenue for the quarter was steady, which means that revenue for just the first half of FY20 will exceed the total revenue generated by our business in FY19,” he said. 

“I am also very happy to announce that we received our R&D tax rebate of over $2m which is a 15% increase over the previous year. Q2 was also the quarter where we were able to name two key strategic end customers, the Rural Connectivity Group (RCG) in New Zealand and Vodacom in South Africa.  Both have begun deploying our batteries.”

Other highlights from the past quarter include:

  • Attractive growth opportunities for Redflow batteries in South Africa and sub-Saharan Africa due to increasingly severe power outages in South Africa and frequent theft or vandalism of lead-acid batteries 
  • Delivery of Redflow’s unique, compelling solution for the telco market, based on its long duration batteries, with an ability to work in harsh conditions, and anti-theft features
  • A remote WA deployment of Redflow’s temperature-tolerant batteries, which are well-suited for the Australian rural community requiring an energy storage solution that can thrive in harsh conditions without the fire risk of other chemistries.

“In summary, we have made very good progress over the last 3 months and are very focused on converting initial orders with key customers into run rate business and generating new business with new customers,” said Mr Harris.

Vodacom deploys Redflow batteries to reduce theft and vandalism at South African mobile tower sites

One of Africa’s leading telecommunication companies Vodacom is deploying Redflow zinc-bromine flow batteries at mobile base stations in South Africa to reduce the vandalism and theft associated with lead-acid and lithium batteries. 

In a statement to the Australian Securities Exchange (ASX), Redflow reported that Vodacom’s new use of Redflow ZBM2 batteries specifically to manage battery theft and vandalism is a significant commercial development for Redflow in the large African market. 

This development provides meaningful external validation by a major player in the African telco market of Redflow’s belief that the ZBM2 battery’s resistance to theft and vandalism is an important competitive advantage for the product in the large African market and other emerging economies.

Podcast: Redflow CEO Tim Harris explains why flow batteries are vital to the renewable energy ecosystem

In his latest Wildcatter podcast, veteran stock analysis Peter Strachan asks Redflow managing director and CEO Tim Harris about the opportunities for the company’s zinc-bromine flow batteries.

In this interview, Mr Strachan – a self-described “lover of the oil and gas game” – examines how Redflow has grown to become an Australian-owned technology leader in the area of battery energy storage with a market capitalisation of about $46m.

Redflow’s zinc-bromine flow battery technology is ideally suited for stationary power storage applications that shift energy availability from intermittent generation sources such as wind and solar photovoltaic, enabling that power to be used at night, or when the wind is not blowing.

Mr Harris describes Redflow’s zinc-bromine flow battery as more of a marathon runner than a sprinter for energy storage. “We see ourselves very much as the workhorse of the renewable energy storage ecosystem,” he said.

In this 25-minute interview, Tim Harris outlines his telecommunications industry background, the unique benefits of Redflow’s batteries and the exciting opportunities the company is targeting.

Redflow has identified off-grid and micro-grid applications, including the supply of power to remote telecommunications facilities and remote communities, where traditional back-up generation can also play a part. Redflow’s product has a long working life and can be cycled continuously, coming with a 3650 full-cycle warranty, which far outstrips its peers in the battery storage industry.

Vodafone uses Redflow batteries to store energy for remote telecom tower site in New Zealand

Zinc-bromine flow batteries from Redflow have stored and supplied more than 50 MWh (megawatt-hours) of renewable energy for a Vodafone telecommunications tower in New Zealand during the past three years.

Vodafone NZ’s Kauaeranga Valley tower site is located east of Thames by the Coromandel Forest Park in a remote part of New Zealand’s North Island, Sites such as the Kauaeranga Valley are so remote that it is unfeasible to lay or connect power cables. Alternative power sources, such as diesel generators, come with their own set of challenges including a second generator for redundancy, high maintenance costs and expensive and difficult diesel deliveries.

Vodafone New Zealand has met the challenge of bringing broadband connectivity to the remote site, where no grid power is available, by deploying a best-in-class green energy cell site, powered by Vertiv’s Hybrid Energy Storage System (HESS) with energy stored by Redflow batteries. The site, which contains five Redflow ZBM2 zinc-bromine flow batteries, has improved mobile phone coverage and high-speed wireless broadband for thousands of locals and visitors in the region.
