Vanadium Redox Flow Battery - Energy Storage System (VRB-ESS™)

The VRB-ESS can economically store and supply large amounts of electricity on demand and is focused on stationary applications. It is a long life, cost effective, low maintenance, efficient technology that allows for the scalability of power and storage capacity independently. The VRB-ESS is particularly beneficial to renewable energy providers, utilities and end users through its ability to “inventory” electricity, allowing for the optimal match of supply and demand. The VRB-ESS is well suited for a variety of applications. Enabling the provision of “firm” capacity from intermittent renewable generation such as wind and solar; more cost effective and efficient generation of electricity in remote areas; capital deferral for utilities; and load leveling (peak shaving) applications. The VRB-ESS is also capable of providing backup power solutions including applications for utility sub-stations and telecommunication sites. The VRB-ESS is characterized by having the lowest ecological impact of all energy storage technologies and is unlike most other conventional energy storage systems that rely on substances such as lead or cadmium.
