Chinese scientists build polysulfide-iodide redox flow battery with 87.9% energy efficiency
Scientists in China designed a suplhuer-based redox flow battery with a peak power density of 95.7 mW cm2 and an average energy efficiency of 76.5% at 30 mA cm2 within 50 cycles.
Go with the flow (batteries)
There is a gap in the market for long-duration energy storage (LDES), according to US-based manufacturer ESS Inc. – one which can’t be plugged with lithium-ion chemistry. Hugh McDermott, of ESS Inc. tells pv magazine how he thinks iron flow batteries fit into the energy system of the future, as the company pursues global expansion.
World’s largest vanadium redox flow project completed
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-made vanadium flow battery project could offer storage cost of $166/MWh
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).
China to host 1.6 GW vanadium flow battery manufacturing complex
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.
Switzerland to host world’s largest redox flow storage project
