Distributed Storage

Lithium-based energy storage volumes in the U.S. are expected to grow by multiple orders of magnitude in the coming years, with a 1000% capacity increase by 2023.

As technology redefines the delivery of network services, grid operators in remote areas the world over are searching for more cost-effective and reliable alternatives to traditional poles and wires. Standalone power systems are the solar application that is at the forefront of the switch, and they’re ramping up fast.

Victorian distribution network provider United Energy will deploy 40 custom-built community batteries across Melbourne’s southeast as part of an $11 million project designed to better manage the increasing penetration of rooftop solar PV and periods of peak demand on the network.

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%.

Japanese scientists have developed a new lithium-sulfur battery by using titanium oxide and titanium nitride to prevent the formation of polysulfides during the fabrication process. This allows the battery to retain 85% of its capacity after 500 cycles at 2 C.

Ambri has secured US$144 million ( AU$195 million) to commercialise its calcium-antimony liquid metal battery chemistry and open manufacturing facilities to deliver projects in 2023 and beyond.

Energy Source, a Brazilian battery specialist, is currently providing energy storage services with reused and recycled batteries. Battery recycling and related metals recovery are conducted separately, without the burning of materials.
