New AEMC rules may create opportunities for Redflow

New Australian Energy Market Commission (AEMC) rules mean that networks could soon replace lengthy and costly poles and wires for households and businesses in remote and disaster-prone areas with stand-alone solar and storage systems.

This generates opportunities for Redflow’s robust long-duration energy storage technology which is well suited to these applications as shown by customers from Yallalong station in outback WA to remote Ban Pha Dan village in northern Thailand. https://reneweconomy.com.au/networks-can-now-replace-costly-poles-and-wires-with-solar-and-storage-micro-grids-93400/

Redflow Managing Director and CEO Tim Harris with ZBM2 batteries

Redflow receives subsequent order of flow batteries for New Zealand’s RCG

Redflow Limited (ASX: RFX) has received a subsequent order for its ZBM2 zinc-bromine flow batteries for deployment by New Zealand’s Rural Connectivity Group (RCG).

Redflow, which supplied an initial eight batteries for use by RCG in November 2019, has received a follow on order for an additional 10 batteries for installation at two new off-grid RCG telecommunications transmission towers in the North Island of New Zealand. Local RCG partner Switchboard Services has placed the order and will undertake ZBM2 installation works.

This repeat order follows the successful installation and commissioning of Redflow’s ZBM2 batteries at two RCG towers late last year.

Redflow Managing Director and CEO Tim Harris said this order for ZBM2 batteries at further RCG sites demonstrated the benefits that Redflow’s zinc-bromine flow battery technology delivered to telecommunications companies. “These benefits include long-life performance, heat-tolerance and theft-resistance,” he said.

“This builds on the interest and demand we have seen from Vodacom and Moropa in South Africa and Optus in Australia last year. We are extremely pleased to continue to solidify our product positioning as an energy storage technology of choice in the telecommunications market for off-grid and weak grid environments.”

About the RCG programme

The RCG programme is a venture between the New Zealand government and the three mobile network operators in New Zealand: Vodafone, Spark and 2degrees, to provide or enhance 4G mobile and wireless broadband coverage in New Zealand for off-grid and on-grid environments with a focus on rural areas and areas impacted by black-spots.  The Redflow ZBM2 zinc-bromine flow battery has been selected for use on off-grid sites and is particularly well suited to the requirements of this application. The batteries provide long duration run times for sites powered almost exclusively by PV solar panels, with a backup generator used in winter conditions.

The batteries provide 100% cycling capability each day to maximise the utilisation of the solar generation and that daily cycling capacity does not degrade with utilisation or at elevated temperatures up to 50ºC. The 10-year life of the Redflow ZBM2 with minimal maintenance makes for a cost-effective total-cost-of-ownership over the long haul.

Redflow batteries at Swansea University in Britain

Swansea University chooses Redflow flow-batteries for its renewable energy Active Building demonstrator

Swansea University, a research-led British university, has purchased Redflow’s unique ZBM2 zinc-bromine flow battery technology as the energy storage backbone for its Active Building demonstrator -– an award-winning classroom that generates, stores and releases solar energy at the point of use.

The microgrid is built around 120 kWh of Redflow batteries and is supplied with building-integrated, thin-film photovoltaic solar panels, as well as a solar wall that supplies the warm air to a heat-pump for space and water heating.  Since being built, the classroom has proven the Active Buildings concept by generating more energy than it has used over an annual cycle, and during high solar summer months, the system will return power to the local electricity grid.

Redflow’s small 10 kWh flow battery units are the only commercially available flow battery energy storage system that allowed accurate sizing for the 120 kWh system. Additionally, the Redflow battery operates “out of the box” with the Victron inverters and controllers that provide the power conversion for the Swansea University minigrid.

Tom Griffiths, Technology Transfer Fellow (Smart Systems), said Swansea selected the Redflow technology because of its ability to deliver 100% of the rated system energy every day, without degradation in capacity over a long – 10 year – life. “These characteristics were crucial considerations for us, and our application requires battery discharge duration of 4-8 hours depending on the time of year, making Redflow’s flow battery the ideal fit for our requirements in comparison to more conventional lead-acid or lithium alternatives.”

Off-grid WA orchard beats bushfire blackouts with Redflow batteries

After losing power as the night horizon glowed orange with bushfires last summer, WA orchardists Jeff and Kerry Murray installed Redflow batteries to take their property off-grid and make it energy-independent year-round.

Power outages have plagued the Murrays’ farm – called Kalyakool, a Noongah word meaning “forever more” – since they bought the 34-hectare property near Gingin, 90km north of Perth, in 1994.

Mr Murray said the threat from the December bushfire was “the last straw”. “Our water comes from two bores, so without power, we can’t get any water,” he said. “The summer fire didn’t get to us, but it impinged on us through the loss of power for a whole day, which was followed by multiple outages as they brought it back on. If fire does reach us, we need energy to run the pumps to defend our property, which is why the bushfire was the last straw for us.”

Coronavirus disruption has minimal impact on Redflow reports MD & CEO Tim Harris

In light of the World Health Organization’s declaration earlier this week that the COVID-19 coronavirus is a pandemic, I wanted to take a moment to let you know Redflow’s position and our response.

Overall, the widely reported disruption caused by the virus is having a minimal impact on Redflow’s operations. Redflow continues to operate its Thai manufacturing facility and we have a sufficient level of finished batteries to fulfil current orders and immediate sales opportunities. Our manufacturing facility in Thailand continues to operate on a business-as-usual basis under the supervision of our long-time Operations Manager, Praveen Kannankai.

Redflow currently maintains a healthy level of battery stocks in Thailand as well as in our main markets of South Africa and Australia. These finished batteries are available for immediate delivery while our Thai factory has a sufficient level of raw materials to fulfil our current manufacturing plans. Although we source materials from around the world, including China, we do not anticipate any significant impact from coronavirus disruption over the short to medium term. We continue to monitor the situation closely and remain in close contact with key suppliers. While the recent COVID-19 outbreak has delayed business development opportunities in China, Redflow plans to resume discussions with potential partners and customers at the appropriate time.

Given the dynamic nature of the virus and a prudent approach, we have undertaken appropriate travel protocols and contingency planning to maintain business operations if the situation deteriorates further.

We are monitoring the situation daily and will continue to implement any necessary measures to help protect our people and our business against the spread of the coronavirus, while we continue to execute on our growth strategy.

Thank you for your ongoing support of Redflow.

Kind regards
Tim Harris

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.
