flow batteries

Australian Vanadium Limited’s plan to establish a major vanadium mine in Western Australia’s mid-west have firmed up with its proposal receiving the tick of approval from the state’s Environmental Protection Authority.

As flow battery technology comes of age, Australia’s capacity to mine the critical minerals required, and manufacture flow batteries has a promising future on the back of embracing automation and supported by government funding.

The need for long-duration energy storage in a net-zero world is undeniable but with conventional battery prices tumbling, can anything dislodge the mainstream grip of lithium ion? S&P Global’s Susan Taylor provides an update on non-lithium storage technologies.

A global team of researchers and industry collaborators, led by RMIT University in Melbourne, have invented recyclable “water batteries” that potentially mitigate safety concerns for large-scale grid energy.

The global flow battery market will expand from USD 289 million in 2023 to USD 805 million by 2028, driven by increasing investments in renewable energy and flow batteries’ advantages over conventional products. The newly released report also highlighted Australia, noting the nation has numerous flow battery projects for various applications.

Queensland zinc-bromine flow battery maker, Redflow, has announced its batteries have successfully been integrated with Chinese brand Deye’s hybrid inverters. Redflow says the integration “provides a range of new capabilities previously unavailable to the Australian market.”

US researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.

Bromine-based flow batteries have the potential for high energy density in renewable energy storage. Their commercial adoption, however, remains challenging due to the cathode materials used for their construction. New research from China seeks to shed light on how to overcome these hurdles.

Developed by Dutch start-up AquaBattery, the storage technology is claimed to independently amend power and energy capacity. The battery system utilises three storage tanks, one with fresh water, one with concentrated salt water and one with diluted salt water, and also relies on membrane stacks.

Brisbane-based flow battery company Redflow has completed its single biggest installation to date, a 2 MWh storage system in California for biowaste technology firm Anaergia.
