The VRB® Energy VRB-ESS® electrolyte never wears out, and can be charged and discharged an almost infinite number of cycles. 

Our utility-scale systems last for 25+ years and offer the lowest lifecycle cost of energy (LCOE) of any type of battery storage.

VRB Energy’s deep-discharge, long-life utility-scale energy storage solutions are ideal for integrating renewable energy, increasing power grid system efficiency, providing operational flexibility and delivering grid resiliency.

To address the increasing threat of climate change, the world needs this combination of renewables and storage. This combination is already the most cost-effective energy solution in many parts of the US and the World.

On a global scale, VRB Energy has the most advanced flow battery technology and proven utility-scale deployment capabilities.

Our VRB-ESS® provides 4+ hours of energy storage for daily cycling to firm up wind energy, time-shift solar energy, and manage stability for microgrids.

ENERGY STORAGE SOLUTIONS

VRB-ESS® MW-Class

VRB-ESS® are based on a 250kW or 500 kW containerized module

Suitable for deployment at utility substations, as well as at commercial and industrial sites – in support of solar, wind or microgrids.

INTELLECTUAL PROPERTY

Our innovation is delivering a path to better, faster and more economical energy storage.

Our proprietary ion-exchange membrane, long-life electrolyte formulation and innovative cell stack flow field design yield numerous cost and efficiency advantages.  

VRB Energy currently has more than 40 major patents worldwide. These range from core stack design, to electrolyte composition, to system-level design, as well as application-level patents covering integration of energy storage into microgrid and grid balancing applications. 

Our proprietary technology ensures a battery that is safe for operation in a wide range of temperatures – and gives us cost and performance advantages over other flow battery providers.

“The world will see more than 1,000 gigawatts of battery capacity added between now and 2050 in support of integrating renewable energy, and our VRB technology is ideally suited for this.”

Robert Friedland, Chairman, VRB Energy

A SCALABLE APPROACH BUILT ON A COMMON BATTERY MODULE.

The result is that customers can expand their storage requirements from 4 hours 8 hours or more, simply by adding additional tanks and electrolyte in order to meet their needs.

VRB ENERGY AWARDED 3MW/12MWH PROJECT CONTRACT: THE LARGEST FLOW BATTERY INSTALLED IN CHINA.

"We selected a vanadium flow battery because they have superior safety, reliability and lifecycle economics compared to lithium-ion and other battery types. We selected VRB Energy because it is the leader in China with its VRB technology, and has a track record of performance with State Grid Corporation of China."

Mr. XIE Guanggua, Chairman, Hubei Pingfan
