redox flow battery

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.

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.

UK scientists have designed a new type of aqueous organic redox flow battery based on ion-exchange membranes made of a polymer of intrinsic microporosity. The battery showed a very low-capacity decay rate of 0.0335% per day for 2,100 charge-discharge cycles.

Australian redox-flow battery specialist Redflow has upped the ante on its plans to expand into the US market, announcing that it has completed testing to pave the way for its battery energy storage system to be used in conjunction with hybrid inverters manufactured by US solar engineering company Sol-Ark.

MSE international and its partners have concluded the feasibility study for an organic large-scale flow battery project in Portsmouth, England. The 650 kW/6.1 MWh project might end up having have a lower levelized cost of electricity than lithium-ion or vanadium redox flow batteries.

A Dutch-Danish research group has provided a proof of concept for the use of Blatter radicals in electrochemical energy-storage applications. It tested these compounds in a small electrochemical cell that was found to remain stable over 275 charge/discharge cycles.
