Perth startup VSUN Energy is developing a home battery storage system that could help Australian households become independent of the electricity grid.
The residential Vanadium Flow Battery promises to revolutionise how households capture and store energy. The technology could mean suburban Australian homes become independent of the electricity grid.
The batteries are designed to be linked to household solar panels, now commonly seen on the roofs of millions of Australian homes.
The storage systems will help homes stay off the grid completely overnight or when the sun isn’t shining. The batteries are designed to capture and feedback electricity in down times for many hours.
The vanadium batteries are designed to last at least 20-years and are non-flammable.
The company began pushing ahead with plans to develop a Vanadium Redox Flow Battery (VRFB) for the Australian residential market in 2020.
VSUN, a subsidiary of Australian Vanadium Ltd (AVL), last year appointed Western Australian engineering firm Cadds Group to undertake design and consultancy work on its 5 kW/30 kWh residential VRFB in Cockburn south of Perth.
VSUN said the battery will be in market in 2021, as the company looks to benefit from a growing demand for battery energy storage systems in residential and small business settings.
“By initiating market growth in smaller systems we anticipate a knock-on effect for larger VRFB uptake, which in turn will grow the market for vanadium pentoxide in energy storage,” Managing Director Vincent Algar said.
