Ann: New Generation Electrolyte Developed for V-KOR Battery, page-10

Excerpt ----
--- An important attribute of VRFB systems is that their energy storage capacity is independent of the power rating, allowing them to be designed for highly specific energy and power requirements and making them well suited to applications with large energy storage capacity specifications. These batteries are currently used for grid scale energy storage applications where large-scale and long duration electrical energy storage is required. They are an ideal solution for rapidly growing intermittent renewable energy generation sources such as solar and wind.

More suitable for larger scale commercial purpose !
