An iron-chromium flow battery, a new energy storage application technology with high performance and low costs, can be charged by renewable energy sources such as wind and solar power and discharged during peak hours.
[pdf] Disadvantages are also very obvious, vanadium battery energy density is low, can only reach 40Wh/kg, with a lithium-ion battery difference of more than ten times; vanadium battery cost compared to other liquid current batteries, such as iron and zinc, is much higher, and covers a large area, the working temperature range is narrow, limiting the application of vanadium batteries.
[pdf] Breaking down a typical 100kW/400kWh vanadium flow battery system: Recent projects show flow battery prices dancing between $300-$600/kWh installed. Compare that to lithium-ion's $150-$200/kWh sticker price, but wait—there's a plot twist.
[pdf] A AU$20.3 million (US$15.36 million) project to demonstrate the capabilities of utility-scale vanadium flow battery storage in combination with solar PV has been announced in South Australia, with the Federal government helping to fund the project.
[pdf] Sumitomo Electric is pleased to introduce its advanced vanadium redox flow battery (VRFB) at Energy Storage North America (ESNA), held at the San Diego Convention Center from February 25–27, 2025.
[pdf] Relying on Panzhihua's rich vanadium and titanium resources, the project will invest approximately 1.6 billion yuan to build Sichuan Province's first vanadium liquid flow energy storage demonstration base with the largest single unit and the longest storage time, with a storage scale of 100MW/500MWh.
