redox-flow batteries

A Chinese-Finnish research team has identified composite membranes as the best future option for non-aqueous redox flow batteries.

Australia’s Redflow has unveiled its new Energy Pod Z module.

A new South Australian big battery will show the value of diverse storage deployments in the National Electricity Market.

Australian Vanadium filed a patent application this week for its vanadium processing route, while rival TNG signed a deal to commercialize vanadium redox flow batteries.

The factory will be built by VRB Energy in the Hubei province, where it also wants to deploy a 100 MW solar park linked to a 100 MW/500 MWh vanadium flow battery.

Redflow has agreed to supply biowaste specialist Anaergia with a 2 MWh energy storage system, while Perth-based Technology Metals has signed a deal with Japan’s LE System to potentially make vanadium electrolyte in Australia.

The Australian government has recognized TNG’s flagship Mount Peake Project – a mine that includes production plans for vanadium redox flow batteries and green hydrogen – as nationally significant.

Argonne National Laboratory researchers have found a way to use fluorescence to monitor the performance of redox flow batteries in real time. They used 2,1,3-benzothiadiazole as a redox-active molecule to store energy in the electrolytes. The molecule works as an energy carrier and signals a problem known as “crossover.”

UK researchers have used standard carbon paper electrodes modified with electrophoretically deposited nitrogen-doped graphene (N-G) to improve the electrochemical performance of hybrid redox flow cells utilized in redox flow batteries. According to their findings, these electrodes are capable of meeting the harsh electrochemical requirements for these HRFCs and offer enhanced performance and operability.

Australian Vanadium is pushing ahead with plans to develop a vanadium redox flow battery for the Australian residential market, via its VSUN Energy subsidiary.
