Energy Storage

Hydrostor has selected an engineering company to provide front-end studies for a 500 MW compressed air energy storage project in California.

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.

Renewable energy investors have proposed more than 40 new clean energy projects totalling more than 17 GW of generation and storage capacity for a coordinated renewable energy zone to be established in the Illawarra region on the New South Wales south coast.

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.

Construction has commenced on a $45 million grid-scale battery storage system that will support further uptake of solar PV among households and businesses in the Northern Territory and help the government achieve 50% penetration of renewables into its energy supply by 2030.

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.

The biggest battery yet connected to the grid in Queensland has commenced full commercial operations with developer Vena Energy announcing it has flicked the switch on the 100 MW/150 MWh Wandoan South battery energy storage system in the state’s south-west.

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.
