vanadium redox flow batteries

Following their review of redox flow battery research, Norway-based scientists told pv magazine that despite its high upfront capital costs and lower energy density relative to metal-ion, the technology can offer safety, reliability, and scalability advantages for standalone, large-scale applications.

Dalian-headquartered Rongke Power has completed the construction of the 175 MW/700 MWh vanadium flow battery project in China, growing its global fleet of utility-scale projects to more than 2 GWh.

Australian Vanadium Limited (AVL) has moved a vanadium flow battery (VFB) project to design phase with the aim of developing a modular, scalable, turnkey, utility-scale battery energy storage system (BESS).

The all-vanadium liquid flow industrial park project is taking shape in the Baotou city in the Inner Mongolia autonomous region of China, backed by a CNY 11.5 billion ($1.63 billion) investment. Meanwhile, China’s largest vanadium flow electrolyte base is planned in the city of Panzhihua, in the Sichuan province.

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.
