AUSTIN, Texas – October 4, 2016 – ViZn Energy Systems Inc. (ViZn), a leading provider of non-toxic flow battery energy storage systems, announced today that it is offering an optional 95 percent power guarantee on their large scale energy storage systems for up to 20 years. This guarantee will be available to supplement ViZn’s best-in-class comprehensive warranty which is offered in multiple durations up to 20 years, twice the industry average. The guarantee is straightforward, simple, and is independent of battery duty cycle or energy throughput.
“Lithium-ion battery life and their constrictively weak warranties have been one of the limiting factors for the widespread adoption of energy storage,” said Ron Van Dell, CEO of ViZn Energy Systems. “Our flow batteries have been thoroughly evaluated by Black and Veatch for longevity and performance over a long system life. The system’s long term warranty and ability to deliver 95 percent of the rated power for 20 years will give utilities, developers, and banks confidence that their energy storage is engineered to last as long as the infrastructure or generation system it is typically coupled with. We hope to bring simplicity and consistency to a space that has been riddled with partial-coverage warranties.”
ViZn’s unprecedented guarantee is made possible because, unlike lithium-ion batteries, their flow batteries avoid traditional wear out mechanisms that can degrade battery power and capacity over time. Contrast this with other stationary storage systems that are frequently oversized up to 40 percent to account for anticipated power losses and have life-limiting dependencies on temperature, discharge power, and cycle count. In economic terms, developers, installers, and integrators can count on a ViZn Energy stationary storage system to provide unmatched ROI as it delivers high power services and high energy capacity for the life of their system. There is no longer a need to account for added costs such as cell replacement, out-of-coverage O&M, and reduced performance like with a typical lithium-ion system.
ViZn’s flow batteries are manufactured by Jabil’s ISO 9001-certified production team in Florida and the technology utilizes a non-toxic, low-cost zinc and iron chemistry that makes sighting and permitting relatively painless. Unlike lithium-ion systems, ViZn’s versatile flow batteries are capable of performing both high-power and long-duration applications, which allows end users to incorporate multiple value
streams and realize more favorable ROI than other energy storage technologies. ViZn is currently building the largest flow battery in North America and is on track to be the largest global producer of flow batteries by the end of the year.
