ViZn Energy, Inc. products

The GS200 Energy Storage System is self-contained, modular storage system delivering the most cost-effective and safest energy storage on the market. The zinc/iron flow battery incorporates the most efficient and worry free non-acid chemistry available today. The flexible GS200 modules can be interconnected for higher power and energy requirements.

The Z20 Energy Storage System is self-contained in a 20-foot shipping container. On-board chemistry tanks and battery stacks enable stress-free expansion and unmatched reliability. Three to five battery stacks per Z20 provide 48 kW to 80 kW power with 160 kWh energy. Automated ventilation is the only temperature control needed. Systems are easily interconnected for higher power and energy requirements.

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.
