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] 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] 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] 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] In 2025, average turnkey container prices range around USD 200 to USD 400 per kWh depending on capacity, components, and location of deployment. But this range hides much nuance—anything from battery chemistry to cooling systems to permits and integration.
[pdf] VRB Energy is a fast-growing clean technology innovator that has commercialized the largest vanadium flow battery on the market, the VRB-ESS®, certified to UL1973 product safety standards.
