vanadium redox flow batteries

Vanadium redox flow batteries are a type of rechargeable energy storage system that uses liquid solutions of vanadium ions to store and release electrical energy. These solutions are stored in large tanks and circulated through a cell stack, where chemical reactions generate electricity. Because the energy capacity depends on tank size, they can be scaled up easily, making them ideal for large-scale applications like grid power storage. They are durable, can be charged and discharged repeatedly, and have long lifespans, making them a reliable solution for balancing electricity supply and demand from renewable sources like wind and solar.
