Energy Storage

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.

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.

Queensland’s transition to a renewable energy future is set to progress with the state government calling for tenders for the proposed 1 GW Borumba Dam pumped hydro energy storage project while work on a nearby 176 MW solar farm has also reached a new milestone.

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.
