What is a VRFB energy storage system?
This next-generation energy storage system is designed to enhance large-scale energy storage with greater longevity, improved energy density and increased cost efficiency. Additionally, the VRFB improves economical effectiveness through advancements in material development and optimized system design.
What does VRFB stand for?
Japanese manufacturer Sumitomo Electric has released a new vanadium redox flow battery (VRFB) suitable for a variety of long-duration configurations. Unveiled at Energy Storage North America (ESNA), held in San Diego from February 25–27, , the system applies “newly developed long life materials” which allows for a 30-year operational lifespan.
How does the new VRFB system work?
Furthermore, the new VRFB is said to “reduce the overall costs by 30% through optimized system design, improved electrolyte circulation control, and enhanced manufacturing processes”. The system comes in three versions with six, eight and ten hours of storage duration.
How long does a VRFB last?
Through optimized system design, improved electrolyte circulation control, and enhanced manufacturing processes, the new VRFB reduces overall costs, making it a more economical choice for large-scale energy storage projects. By developing long-life materials and ensuring proper maintenance, the VRFB offers an operational lifespan of up to 30 years.
Does Sumitomo Electric's VRFB technology support long duration energy storage (LDEs) applications?
At ESNA, visitors will have the opportunity to explore real-world deployment examples and gain insights into how Sumitomo Electric’s VRFB technology supports Long Duration Energy Storage (LDES) applications. Visit Booth # to explore the product’s capabilities and discuss potential applications with our experts.
Is a VRFB flammable?
As in all VRFBs, electrolyte is not flammable and all components use flame retardant materials, meaning the system is not classified as hazardous under fire safety regulations. “No special hazardous material permits or on-site hazardous materials handlers are required,” Sumitomo says.
