ViZn Energy Systems Expands Capabilities of its Best-in-Class Grid-Scale Flow Battery Energy Storage System

Vanguard II enhances current technology, enabling fully dispatchable revenue grade power across full range of storage applications

AUSTIN, Texas, - ViZn Energy Systems Inc. (ViZn), a leading provider of energy storage systems for microgrid, commercial & industrial and utility applications, announced today that it has built upon its best-in-class proprietary flow battery technology to enhance the capabilities, reliability and lifetime of all next generation flow battery systems for multi-megawatt energy storage applications. The Vanguard II battery stack further expands the operating range of ViZn's systems, strengthening their industry-leading long-duration energy services by enhancing the fast switching and high power cycling capabilities required for many applications, further maximizing ROI and providing industry-leading payback periods.


The Vanguard II battery stack has demonstrated 20 percent greater capacity and is immune to cycle life degradation, providing more headroom to handle spikes in power requirements for demanding and unpredictable applications on both sides of the meter. All ViZn flow batteries incorporate the new Vanguard II stack control technology which eliminates life-limiting issues such as dendrite growth, simplifies cell balancing, and removes thermal and electrolyte breakdown issues associated with high frequency power switching. This unique multi-use capability is necessary for frequency regulation and other high power applications while adding value to longer duration storage. All of ViZn's systems are highly scalable, adding value for even the largest utility requirements. By interconnecting multiple units, both power and energy capabilities can be increased to offer utilities, as well as commercial & industrial customers the optimal fit for any size project.

ViZn's current flow battery systems can be seamlessly upgraded with the Vanguard II battery stacks, increasing the capabilities and application flexibility of customers' current assets and making existing systems even more efficient across the remaining life of the battery.

"We're seeing an increasing interest in a flexible large-scale energy storage platform," said Ron Van Dell, CEO of ViZn. "Our customers are deploying ViZn systems because of the unique mix of applications requiring both energy and power capabilities that only our flow battery systems can address. Our continuous innovations in flow battery stack advancements give users an inherently versatile battery that can be run at very high power for short durations with millisecond response times and also dispatch energy over a long period of time, addressing both frequency regulation and peak shaving simultaneously without concern for battery state of charge (SOC). The ability to stack revenue streams and applications on both sides of the meter addresses the uncertainties about the kind of services customers will require 10 or 20 years down the road, future-proofing ViZn's technology against a changing mix of applications requirements."

All of ViZn's systems utilize the inherently safe, non-toxic, non-explosive zinc-iron electrolyte that incorporates ViZn's industry-leading performance guarantee over the life of the system.
