ViZn Energy - Flow Rechargeable Batteries
A flow battery is a type of rechargeable battery where the battery stacks circulate two chemical components dissolved in liquid electrolytes contained within the system. The two electrolytes are separated by a membrane within the stack and ion exchange across this membrane creates the flow of electric current while both liquids circulate in their own respective space. The maximum power, in kilowatts, of any flow battery is determined by the number of stacks in the power unit as voltage is built up with more stacks. The amount of energy any flow battery, in kilowatt hours, can deliver is determined by the volume of the tanks. Larger tanks lead to longer duration.

Why ViZn Energy is Revolutionary
ViZn Energy’s core technology, chemistry and robust packaging is the result of more than 8 years of engineering and R&D into the most promising energy storage technology available. Our value lies in our ability to simultaneously deliver high-power and long-duration energy services. (Most battery technologies can only excel at one aspect.) The ViZn battery achieves this unique performance blend by utilizing a hybrid flow battery in which alkaline electrochemical components are dissolved in the electrolyte.
Counter to nearly every commercially available energy storage solution, our systems run on a safe chemistry that is non-toxic, non-flammable, and non-explosive. The electrolytes used in the ViZn system are food grade and found in abundance at commodity prices. ViZn’s products deliver unmatched level of performance without sacrificing safety.
The Fundamental Benefits
Energy storage is the enabling technology for the modern electric grid. ViZn Energy storage systems are the safest and most robust solutions under all operating conditions. Our systems can tolerate extreme high-temperature environments and deliver under intense duty cycling across the full state of charge.
Reliability
Our systems require minimal maintenance over their 20-year life and they are designed to be easily recycled at the end of their life. Our 20-year warranty places zero limitations on duty cycle, depth of charge/discharge, or ambient cell temperature. Our products are manufactured by our strategic partner Jabil Circuit Inc. in state-of-the-art manufacturing facilities.
Protecting your investment for decades, the 20-year Performance Guarantee Program covers 20-years of operation and maintenance costs, including parts, labor and expenses for the best-in-class energy storage system.
The confidence we have in our products is echoed in our comprehensive 20-year warranty. ViZn offers the industry’s leading warranty and support services.
20-years of expected cell life exceeds other technologies by up to 3X. Our system is engineered for reliability. Our use of alkaline electrolytes eliminates the pump and component erosion that other flow batteries face with their acidic chemistry. Built in and robust remote monitoring ensures that the owner can keep an eye on the system and obtain low cost operation & maintenance.
Feel free to cycle our battery at full power, from 100% state of charge to 0% and back to 100% again multiple times a day. We have achieved over 1 million cycles (the equivalent of 27-years) without any capacity changes or impacts on revenue-grade performance.
Frost & Sullivan recognized ViZn Energy Systems with “Entrepreneurial Company of the Year Award” for Energy Storage. Intersolar, the World’s Largest Exhibition for Solar Industry recognized ViZn for it’s “excellence and innovation” in Energy Storage.
ViZn System’s flow batteries are self-contained, modular storage system delivering the most cost-effective and safest energy storage in a format that scales easily from 50 kW to 100 MW. We employ the most efficient and worry-free non-acid chemistry available today to yield a solution that is inherently non-toxic, non-explosive and non-flammable.
- High power, short duration: Millisecond switching between charge and discharge cycles enables rapid- response applications such as demand charge reduction and wholesale grid regulation services.
- High capacity, long duration: More than 8 hours discharge at nominal rated power output, and up to 4 hours continuous discharge at maximum rated power output.
- State of charge access: Access to full capacity of the battery (100% state of charge) without damage, enabling more usable output than competitive batteries.
- Heavy duty cycle: Cycle for more than 20-years at high frequency and at high power several times per day without degradation, cell replacement or life reduction.
- Safety: Non-toxic, non-explosive and non-flammable materials that do not pose a risk to people, communities or the environment.
- Efficiency: No HVAC for regulating internal temperatures results in competitive “all-in” round trip efficiency with nearly all commercially available energy storage systems.
