MoU for vanadium redox flow battery collaboration in Australia


ASX-listed Australian Vanadium Limited (AVL) has signed a non-binding Memorandum of Understanding (MOU) with EPC provider and supplier of high-end critical uninterruptible power supply systems Metrowest Power Systems, to pursue opportunities for deployment of vanadium redox flow battery technology (VRFB) in Australia. The companies hope to push forward with larger projects and pave the way for the VRFB technology to demonstrate its strengths.

The new alliance will rely on Metrowest’s track record and connections in industrial and utility sectors and the financial, marketing and technical capabilities of AVL and its 100%-owned subsidiary VSUN Energy, provides promotion, installation and maintenance of energy storage solutions using VRFB. “This agreement will allow the companies to work together to bring to fruition some of the bigger project opportunities that we’ve been unable to tackle on our own,” AVL Managing Director, Vincent Algar, said. “VSUN’s marketing and energy analysis has been very successful, but with a lack of experience in implementation it has certainly been difficult to persuade government agencies, for example, about the aptitude of the company and the VRFBs it offers.”

The MOU is for an initial term of 12 months, during which time the parties will investigate the potential to formalise the partnership. VSUN Energy alongside Metrowest will continue to offer VRFB from a variety of manufacturers, with joint projects being focused on 250kW/1MWh up to the multi-megawatt size.

Looking to become a new low-cost vanadium producer, AVL is developing its Australian Vanadium Project, one of the highest-grade vanadium projects globally with 183.6 million tonnes at 0.76% vanadium pentoxide. Proved ore reserves amount to 9.82 million tonnes at 1.07% and the project holds a probable reserve of 8.42 million tonnes at 1.01%. The project is based on a proposed open pit mine; crushing, milling and beneficiation plant and refining plant for final conversion and sale of high quality vanadium pentoxide for use in steel, specialty alloys and energy storage markets. The company has also developed a local production capacity for high-purity vanadium electrolyte, which forms a key component of VRFB.

As for other grid-scale VRFB developments, Canadian company CellCube Energy Storage Systems and Pangea Energy have signaled intention to install a 50 MW/200 MWh vanadium redox flow battery storage system in South Australia. The Pangea Storage Project is in the latter stages of pre-development at a 79-hectare Port Augusta site. Pending due diligence and review the constructions are set to take place in late 2019.
