Redflow batteries at Swansea University in Britain

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 provided 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.”

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.”

Joel Harman 2 WAfter the summer bushfires, the coronavirus pandemic and associated economic shutdown, “unprecedented” must be a standout favourite for Macquarie Dictionary’s Word of the Year for 2020.  For the first time in living memory, Australians - with people around the world - face the dual dangers of dire economic uncertainty along with a truly existential threat from COVID-19 contagion.

Governments globally responded with increasingly severe restrictions to prevent spread of the virus, from insisting on “social distancing” in and lockdowns in several states in Australia to a four-week nationwide lockdown in New Zealand. This coronavirus crisis invites more than just the anxiety of worry, nervousness, or unease about an uncertain outcome: It creates the quite legitimate fear of very real potential danger or harm. So, to get through this crisis as individuals, as well as a community, we need to maintain our mental health as well as protecting our physical wellbeing by observing social and health protocols.
