Energy Storage

With large-scale battery developments emerging as an increasingly important component of Australia’s energy mix, India-headquartered multinational Sterling and Wilson Solar has revealed plans to expand its renewable energy offerings to include providing engineering, procurement and construction solutions for energy storage projects.

Researchers at Monash University have published a new study in which high voltage lithium batteries, such as those used in electric vehicles and grid scale energy storage systems, are tested with a novel lithium salt shown to be far less hazardous than current conventional materials.

Three PhD students from Melbourne are moving their research into recycling lithium-ion batteries from the labs into pitch meetings, vying to become one of the first companies in Australia to recover the metals and minerals from spent batteries. Their method, they say, is simpler, less toxic and more cost competitive than those widely used.

LG Energy Solution has agreed to take 100% of the cobalt and nickel from the proposed Sconi Project in Queensland. The company says the deal will give it an “upper hand” in EV battery production and improve its ESG competitiveness.

German scientists have applied a new combination of cathodes and electrolytes to improve the stability of lithium-metal batteries. They fabricated a device with an energy density of 560 watt-hours per kilogram and a Coulombic efficiency of 99.94%.

The South Australian Greens Party has proposed a tax-and-spend plan for the state that goes against everything the Federal Government advocates, in favour of massive funding of essential services and reducing carbon emissions in the process.

As solar and wind make up larger portions of the energy mix, energy storage is becoming an increasingly important piece of the puzzle in keeping electricity networks running smoothly. And as battery costs fall, new business models are emerging to increase the value of battery energy storage projects for both grid operators and project owners. Focusing on two leading countries – the United Kingdom and Australia – pv magazine looks at what’s in store for large-scale energy storage.

Australia’s proposed 26 GW Asian Renewable Energy Hub has encountered what appears to be a governmental double standard, as the country’s environment minister has rejected an expanded proposal. Thankfully, the project’s proponents have not become discouraged in the face of this double standard; in fact, they’re doubling down.

The tiny Tasmanian town of Derwent Bridge could provide a big boost for the state’s solar PV energy credentials with the small community to play host to a microgrid project that will evaluate how to better meet the energy needs of Australians living in regional and remote areas.

The operators of Australia’s largest solar farm have turned to a software-based bidding solution as they seek to optimise dispatch and manage the facility’s market trading and power purchase commitments amid increasingly market volatility.
