Redflow Limited had a high profile at the Australian Energy Storage Conference & Exhibition 2018, held in Adelaide on May 23-24. As well as demonstrating its range of zinc-bromine flow batteries at the exhibition, Redflow technology evangelist and non-executive director Simon Hackett gave a keynote address at the conference on Thursday, May 24.
Simon, who spoke about “Energy storage technology as the enabler of new energy applications and of new business models”, has published his keynote speech from AES 2018 on his website. Click here to listen to and view Simon’s presentation.
In this synchronised audio recording and PowerPoint deck, Simon poses the question: Will a future grid with large amounts of renewable energy storage necessarily use lithium-ion or other conventional battery systems for most of that large-scale energy storage – or are there better ways? Simon’s presentation examines the role of flow batteries and other energy storage technologies in using renewable energy to build this future energy grid in which “baseload” power generation is on the wane. Simon specifically addresses the need to identify the lifetime environmental impact of ‘environmentally friendly’ energy generation and storage as distinct from just its up-front cost.
At the exhibition, Redflow showcased its ZBM2 zinc-bromine flow battery, which is used for telecommunications, commercial & industrial and grid-scale applications, and its ZCell residential system, which encloses a ZBM2 battery within an attractive weatherproof enclosure.
Redflow Sales Director Andrew Kempster said the stand highlighted the benefits of zinc-bromine flow battery chemistry. “Redflow batteries offer unique advantages over legacy battery types such as lithium and lead-acid,” he said. “These include 100 per cent daily depth of discharge for a warranted 10 years, sustained energy storage capacity of 10 kilowatt-hours for its operating life and tolerance of ambient temperatures as hot as 50 degrees Celsius. In a nutshell, Redflow batteries thrive on heat and hard work.”
Redflow batteries are deployed successfully at locations around Australia and internationally including:
- A six-ZCell off grid deployment on a rural property in western Queensland
- A South African factory that uses 14 ZBM2 batteries to avoid power cuts and high energy prices
- A cottage in rural Victoria that uses two ZCells to live completely off the energy grid.
