vanadium redox flow batteries

Australian researchers are proposing a novel, learning-based H∞ control method to enhance the performance of vanadium redox flow batteries in DC microgrids.

Researchers in the US have demonstrated that replacing the planar lithium anode in a redox mediated lithium-sulfur redox flow battery with a high surface area scaffold enables 10 times faster cycling, up to 10 mA cm−2, without short circuit or voltage instability.

Chinese scientists have analyzed reports of thermal issues with vanadium redox flow batteries (VRFB) and existing thermal management methods. They say the operating temperature should be maintained in the range of 10 C to 40 C to ensure VRFBs with high efficiency, weak side reactions, high electrolyte stability, and low crossover.

Indian researchers have presented a new way to develop effective electrode materials for superpower redox flow battery (RFB) systems. Their flow cell with heat-treated nickel-rich platinum-nickel coating on the graphite felt delivered an impressive ever-best power density of around 1,550 mW cm−2.

AMG Advanced Metallurgical Group has energized its first hybrid storage system based on lithium-ion batteries and vanadium redox flow batteries in Germany. The system reportedly combines the advantages and electrochemical properties of both storage technologies.

Indian researchers have developed a new hybrid system featuring a conventional rooftop PV system, a solar tree, two gravity power modules for building (GPMBs), and a vanadium redox flow battery (VRFB), with power exclusively provided by the two solar installations.

A major Western Australian mine targeting the global vanadium battery market was this week found to be bankable, with feasibility studies confirming the project’s “strong commercial case for development,” its owner Australian Vanadium Limited said.

Researchers in Spain have assembled a 10kW/20kWh vanadium redox flow demonstrator that paves the way for a 50kW battery.

A Spanish consortium is equipping one of Madrid’s largest metro and bus stations with a hybrid system that combines PV, geothermal pumps, and vanadium redox flow batteries to provide cooling and heating.

The US Department of Energy’s Pacific Northwest National Laboratory has made a third semi-exclusive commercial license for vanadium redox flow battery technologies, in order to help bring the technology to market.
