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.
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.
Batteries based on vanadium or zinc bromide represent the cutting edge of redox flow storage tech, an international research team has claimed. They have identified challenges and opportunities for about a dozen redox flow storage technologies, while providing estimates of their current and projected levelized costs of storage.
Australian Vanadium is pushing ahead with plans to develop a vanadium redox flow battery for the Australian residential market, via its VSUN Energy subsidiary.
Scientists in the United States claim that further research is needed to gain a deeper understanding of kinetic stabilization strategies to increase cell voltage in redox flow batteries and bring them closer to commercial viability.
Spanish and Finnish scientists have developed a solar vanadium redox flow battery paired with commercially available CIGS solar panels. The open-circuit voltage values were high enough to achieve unbiased photocharge, they said.
