Distributed Storage

Integrated clean home energy and smart appliances platform lets users run appliances on battery-stored solar energy in pre-determined time frames.

Quick and versatile, batteries are providing a growing number of services to homes, businesses, and on the grid. Electricity network operators are beginning to adopt grid-scale batteries, with the initial applications potentially opening the way for renewable energy to flow more freely and across larger distances than ever before.

Australia’s first lithium-ion battery giga-factory is expected to begin operations soon with battery manufacturer Energy Renaissance announcing the successful completion of a $1.47 million pilot program designed to develop and test its manufacturing processes, systems and plant design.

A former car manufacturing site turn “innovation precinct” in Tonsely Adelaide is now home to one of Australia’s largest rooftop arrays at 4.83 MW. Completed by CleanPeak Energy, the system will supply around 75% of the energy needs of the 56 hectare site, with batteries set to arrive before summer.

A team of Australian researchers have developed a way to use rooftop solar PV to run air conditioners to pre-cool residential and commercial buildings. They have identified several factors that could help reduce a building’s energy costs.

Unprecedented volatility in global commodity markets, disruption to logistics and supply chains, and unrelenting growth has driven up the cost of Li-ion batteries since the middle of 2021. Sam Wilkinson and Oliver Forsyth of IHS Markit expect to see rapid manufacturing expansion that will still struggle to keep up with demand, and ultimately lead to the establishment of a smaller group of battery-makers specialized in supplying stationary energy storage systems.

South Korean solar and battery manufacturer Qcells says its Australian arm has seen 194% growth in energy storage system (ESS) sales in July 2022 compared to the first quarter of the calendar year.

Combining satellite images of Australian rooftops with those of real-time cloud cover to create accurate forecasts of distributed solar output for suburbs and perhaps even whole regions and states is the focus of a new Australian startup, Solstice AI. “We’re kind of at a point now where there’s so much solar that it’s causing all these issues but, if we can forecast it, many of these issues can be alleviated or managed much better,” the company’s cofounder and CEO, Julian de Hoog, tellspv magazine Australia.

Indian researchers have developed a new hybrid system featuring a conventional rooftop PV system, a solar tree, two gravity power modules for building (GPMBs), and a vanadium redox flow battery (VRFB), with power exclusively provided by the two solar installations.

Hype and hope for solid-state batteries (SSBs) continues to grow as industries from automotive to storage bet big on the technology. Leading battery manufacturers and a roll call of start-ups are jostling to get from lab to fab. The reality of SSBs is in question though. As Marija Maisch reports, the window of opportunity for the decades-old technology to make the next big step toward commercialisation is now.
