redox flow battery

Redflow, an Australian redox-flow battery manufacturer, will build one of the world’s largest zinc-based battery energy storage systems in the United States, after signing a multi-million-dollar deal with the California Energy Commission.

UK researchers have assessed the cost of a 24V soluble lead flow battery optimized for PV applications. They have found that a total component cost of GBP 50 ($62)/kWh could be achieved, which is half that of current nickel-manganese-cobalt (NMC) lithium-ion cells.

Infinity Turbine has developed a new system that uses the electricity stored in a saltwater redox flow battery to produce clean drinking water from seawater. It said the technology can be used by cruise ships and cargo ships.

Researchers in China have successfully prepared cobalt oxide-modified graphite felt as an electrode material for an iron-chromium flow battery. The electrode performance significantly improved due to the effects of cobalt, which in turn boosted the energy efficiency and overall performance of the battery.

Singapore-based VFLowTech is manufacturing compact, scalable vanadium redox flow batteries with 24/7 operation over lifespans of 25 years. It is now setting up a 200 MWh production line, with plans to scale up the production of modular, long-duration storage solutions.

Delectrik Systems says multiple units of its 200 kWh battery system can be connected to build MWh-scale energy storage systems for use in on-grid and off-grid applications.

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.

US startup Quino Energy has raised more than $7.8 million to scale up its quinone redox flow battery technology. Harvard University and University of Cambridge researchers came up with the initial research for the battery design.

Scientists in Hong Kong have designed a redox flow battery with electrolytes made of zinc and cerium. They claim to have solved the incompatibility issue posed by these two elements. The device achieved a record average Coulombic efficiency of 94% during cycling.

Dalian Rongke Power has connected a 100 MW redox flow battery storage system to the grid in Dalian, China. It will start operating in mid-October and will eventually be scaled up to 200 MW. The vanadium redox flow battery technology was developed by a division of the Chinese Academy of Sciences.
