redox flow battery

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.

Conceived for the storage of residential and large scale renewable energy, the device has a rated power of over 150mW/cm², an energy density exceeding 40Wh/L, and a power density of 72.5mW/cm². The battery was built with an anode made of inexpensive viologen and its cost, according to its creators, may be lower than $100/kWh.

Canadian companies Invinity and Elemental Energy are planning to couple a 21 MW solar plant under development in Alberta with 8.4 MWh of vanadium redox flow battery storage capacity.

Brisbane-based flow battery company Redflow has completed its single biggest installation to date, a 2 MWh storage system in California for biowaste technology firm Anaergia.

Australian energy storage company VSUN Energy claims to have identified the ‘missing piece of the renewable energy jigsaw’ after successfully testing a standalone electric vehicle battery charger using solar PV supplied by a vanadium redox flow battery.
