Residential vanadium flow battery systems under development for Australia’s solar-storage market
Energy storage systems based around vanadium redox flow batteries (VRFBs) are being developed for residential use in Australia by partners Australian Vanadium (AVL) and Gui Zhou Collect Energy Century Science and Technology.
AVL made an announcement of the news to the Australian Securities Exchange yesterday. While the vast majority of new household battery systems are based around lithium-ion, an AVL representative told Energy-Storage.news that the advantages of a flow battery could include the ability to “store a lot more energy”, while the product is “inherently non-flammable”. The spokesperson also pointed out that the vanadium electrolyte can be reused at the end of the battery’s mechanical lifetime.
A 5kW / 30kWh system will be installed in Perth, Western Australia, to test out the technology and concept and provide feedback for product development. The system is being connected to the grid using an inverter approved by the national Clean Energy Council, which means it can be connected to a solar PV system and used to store energy for self-consumption at the site or for export.
