VIONX Energy has developed a grid-scale, long duration energy storage system delivering unmatched performance over a 20+ year life which is certified non-flammable, safe and bankable. The unique long-duration discharge of up to 10 hours at full rated power is enabled by its world leading flow battery stack technology operating at 3X higher power density than any competitor and proprietary vanadium electrolyte processing.
The VIONX system delivers unrivaled Levelized Cost of Storage at discharge durations greater than 4 hours due to low capital and operating cost and a product life of over 20 years with no performance degradation.
The VIONX VNX product family employs a modular architecture based on 1 MW power and 2 MWh energy building blocks that have been engineered to meet grid reliability standards and have undergone significant durability testing demonstrating up to 40 years of stack life.
VIONX Energy, together with National Grid and the Department of Energy, has installed its second 6-hour duration energy storage system in Shirley, MA. Adjacent to National Grid’s largest solar system, the system will deliver long duration storage in concert with solar power enabling a dispatchable solar solution. The Shirley project employs VIONX Energy’s latest grid-scale architecture offering true power and energy independence through a modular design.

The VIONX Energy storage system delivers unprecedented performance and system reliability. Unlimited deep discharge cycling and the learning from decades of reliability testing combine to deliver greater than 97% uptime and low maintenance cost over a 20 year life and beyond.
The VIONX flow energy storage system is not affected by the depth or frequency of the charge-discharge cycles.
The VIONX flow energy storage system has no performance degradation over the life of the system. Power and duration of discharge remain constant for 20 years and beyond.
The VIONX Flow energy storage system does not require any system augmentation or replacement over the greater than 20- year system life.
The VIONX flow energy storage system is engineered for the grid in modular blocks of up to 2.4MWs and 20MWhs. The only flow energy storage system to employ an architecture separating power and energy to leverage the fundamentally lower cost structure of flow at durations of 4 hours and beyond.
The VIONX flow energy storage system delivers industry leading performance at unmatched cost of storage. Combining low upfront capital cost with substantially lower operating expense provides outstanding project returns. On a total life cycle cost basis, the VIONX flow system can be 20% lower over a 20-year life than conventional storage solutions while retaining substantial residual system value due to the long system life.
The VIONX Energy Corporation has recently demonstrated industry leading energy storage performance by completing four 10-hour energy discharge cycles at full rated stack power over a consecutive four-day period. The nameplate 6 Hour, 3MWh system commissioned in partnership with National Grid over one year ago is being used to conduct the performance demonstration. The VIONX energy storage system located at the Holy Name High School in Worcester is already one of the largest energy storage systems in Massachusetts and one of the largest flow batteries installed in the United States.
The VIONX flow energy system is certified safe for use in urban applications in proximity to adjacent structures. The system employs an aqueous non-flammable electrolyte and physically separated reactants. Double wall containment with integral leak sensing is engineered into every system.
An aqueous, non-flammable electrolyte with physically separated reactants. Double wall containment integral to every container.
Decades of validation with world-class suppliers.
A patented flow field delivers high power at low pressure, minimizing operating stresses. A simple, efficient design lowers cost and maximizes reliability.
The VIONX flow energy storage system is bankable due to the inherent system performance and reliability backed by A+ rated performance warranty insurance from XL Catlin underwritten by New Energy Risk.
