Interesting developments are being made in battery technology with Gelion demonstrating its automated solar light tower at the university of Sydney last month.

“Sydney-based energy storage start-up Gelion has officially launched onto Australia’s booming battery market, with a new take on zinc bromine chemistry it says can offer a cheaper, safer and more sustainable alternative to lithium-ion.
The company unveiled the first commercial application of its Gelion Endure battery storage platform – a battery-integrated portable, automated solar light tower – at the home of its conception, the University of Sydney, at a live demonstration in February 2019.
The technology was unveiled as part of a $1 million contract with the University – the company’s first such commercial deal – which starts with the installation of battery integrated solar light poles across the Sydney campus, followed by plans to add storage to the Universities rooftop solar systems.'‘
And from there, the company’s plans get considerably loftier. With the help of a new $10 million fundraising round – also launched on Wednesday night – Gelion expects to be mass producing its zinc bromine gel battery technology for applications ranging from residential to grid, at a cost of below $100/kWh by the end of 2021.”
While their first focus seems to be more aimed towards commercial/industrial and solar farms their clear intention to move to the residential market could mean competitively priced batteries for on grid homes could be available in the near future.
