The demonstration will integrate AVESS’ VFB prototype and solar PV into an existing disconnected microgrid to power non-essential loads on the Windimurra Vanadium Mine campsite.

The Atlantic partnership signifies a transformational opportunity for AVESS to validate its VFB technology with a proven vanadium developer while cementing AVESS’ position in the Australian mining sector and growing its VFB market share.

The two businesses will now work towards regulatory approvals and definitive agreements.

AVESS Energy managing director Young Yu said, “We are grateful for this opportunity to showcase our VFB, and we look forward to growing our partnership with Atlantic.

“The deployment of our 50Kw/250Kwh VFB at Windimurra represents a significant milestone for AVESS Energy.

“This exciting partnership is another step towards the development of the local vanadium supply chain.”

Unicoh ESS Co Ltd will invest AUD$10.2 million to build a 500-tonne vanadium electrolyte sulfate manufacturing plant on a 24,235sqm site in South Korea’s Yeongil Port Industrial Complex Foreign Investment Zone.

The manufacturing plant is expected to create more than 60 direct jobs in Pohang City. The company is expected to invest AUD$4 million in Unicoh ESS Co Ltd to provide general working capital while strengthening its positioning in the global VFB market.

AVESS is now expected to pursue vanadium offtake opportunities with local vanadium developers to enhance Australia’s vanadium value chain.

AVESS Energy managing director Young Yu said, “The creation of Unicoh ESS and the signing of this vanadium electrolyte manufacturing MoU strengthens AVESS’ capabilities and positioning in the global vanadium electrolyte market, as we edge closer towards Australian-made vanadium batteries.

“Unicoh ESS comes at an exciting time as we synergise decades of complementary capabilities and expertise across the electrolyte space, while this MoU is another demonstration of our readiness to locally manufacture commercial-scale VFBs.”

The global vanadium electrolyte market size is projected to be worth US$126.3 million (2023) and is expected to reach US$537.8 million by 2030, growing at a CAGR of 23% between 2023 and 2030.

The rebranding to AVESS Energy closely follows the company’s successful commissioning of a 50kW VRFB in Perth on January 19, 2024, signifying the Australia-first manufacture of a commercial-scale single-module VRFB.

AVESS Energy is preparing its 50kW VRFB for commercial demonstrations in the mining sector.

AVESS Energy managing director Young Yu said, “Our rebrand to AVESS Energy supports a deeper decarbonisation purpose to provide sustainable, safe, and efficient VRFBs to the energy, mining, and utility sectors.

“The name AVESS Energy represents the capabilities, expertise, and insights that our team brings to Australia’s energy storage mix.

“We understand the complexities and language of energy, mining, and utilities, and our new branding brings us in closer alignment with these sectors.

The vanadium electrolyte facility has the potential to produce up to 33MWh of high purity electrolyte per annum, catering to the growing demands of the vanadium flow battery (VFB) market.

Also on display at the facility was a 78kW/220kWh VFB manufactured by Invinity Energy Systems, which is destined for a Horizon Power project in Kununurra and also a prototype residential 5kW/15kWh VFB.

In 2021, AVL was awarded a $3.69M Federal Government grant, with part of the funding allocated to building and operating a commercial vanadium electrolyte manufacturing facility in Western Australia to support the commercialisation of VFBs and the design of the prototype residential battery.

AVL has used US Vanadium LLC’s (USV) proven electrolyte manufacturing technology for the plant’s design, which has de-risked construction and start-up. USV currently manufactures vanadium electrolyte for the North American market.

AVL holds the exclusive licence for Australia and New Zealand for USV’s vanadium electrolyte manufacturing technology. Until production of vanadium oxides from AVL’s processing hub commences, vanadium oxide feedstock for the electrolyte facility will be sourced from USV’s vanadium production facility in the US.

VFBs were invented in the 1980s at the University of New South Wales by Emeritus Professor Maria Skyllas-Kazacos and her team. They have been commercialised overseas and their popularity as an energy storage device is growing.

Hon. Minister Madeleine King MP said, “Vanadium flow batteries were invented in Australia, and Australian vanadium will play a key role in the energy transition.

“Vanadium production is highly concentrated internationally, and it is on Australia’s Critical Minerals List.

“The Australian Government supports critical minerals projects through measures including the Critical Minerals Facility and the Northern Australia Infrastructure Fund.”

Horizon Power CEO Stephanie Unwin said the pilot would support the organisation’s focus on solving the important technical problem of long duration storage and performance in harsh conditions, providing a pathway to reaching its decarbonisation goals.

“Long duration energy storage provides backup power during times of peak demand or when the power supply is interrupted, storing high volumes of excess energy when demand is low and the ability to shift energy storage into the night. It can also minimise the need for costly fossil fuel generation and grid infrastructure upgrades,” Unwin said.

“The vanadium flow battery is specifically designed to deliver large amounts of energy over a long period of time and is temperature resilient, which is critical for our unique regional and remote networks.

“This is an exciting trial which will allow us to increase our understanding of the technology in a regional energy system and its ability to provide long periods of 100% renewable energy.”

Invinity Energy Systems chief commercial officer Matt Harper said, “Due to their durability, safety and reliability, vanadium flow batteries have a vital role to play in reducing the use of fossil fuels in power generation, particularly in remote communities. Invinity is pleased to be supplying this proven and commercialised technology, that has its roots in Australia, for VSUN Energy and Horizon Power who are spearheading the use of alternative-to-lithium batteries in an important market for Invinity.”

The use of long duration energy storage, in the form of vanadium flow batteries, could assist Horizon Power to accelerate the decarbonisation of its energy network, which covers 2.3 million square kilometres.

The vanadium flow battery will be used for Horizon Power’s long duration energy storage pilot which aims to increase understanding of how this technology can provide long periods of 100% renewable energy supply in regional and remote energy systems across Western Australia.

Site planning and development work is underway, with the battery to be delivered and installed later this year.
