Vanadium Redox Flow Battery System
Vanadium Redox Flow Battery (VRFB) energy storage systems provide safe, long-lasting, and flexible energy storage solutions for renewable integration, grid stabilization, and power backup. Developed in partnership with Sumitomo Electric in Japan, these systems are engineered for reliable operation in both indoor and outdoor environments, supporting power generation, transmission, and consumption.
Key Features
The VRFB system uses non-flammable vanadium electrolyte, provides over 20 years of operational life, and supports flexible charge and discharge cycles. It allows 100% deep discharge without degradation, requires minimal maintenance, and the electrolyte is fully recyclable. The modular design allows capacity to be scaled to meet varying power and energy requirements.
