Vanadium Flow Battery

Imergy Power Systems is a USA based organisation specializing in the manufacture of Vanadium Flow Batteries.

“The world needs radical new energy solutions. Imergy is supplying them now. Our paradigm-shifting Energy Storage Platform (ESP) fits as seamlessly into a remote village as it does into a large-scale commercial application. Cost savings and ROI are deep and fast. Scaling up is simple and inexpensive. Smart technology ensures efficient consumption. And the sustainable design meets today’s highest standards for responsible energy systems.”

Imergy Power Systems specializes in a proprietary, vanadium based flow battery system – the most cost-effective energy storage technology available today. Flow batteries store energy in a liquid electrolyte that circulates between tanks. The simplicity of the design creates a robust and efficient system that can be charged and discharged completely, and cycled thousands of times a year without impact on its lifespan. Integrated power electronics manage the charging and discharging processes, and the unique architecture allows the system to be scaled up in size by simply increasing the electrolyte volumes. Imergy’s Energy Storage Platforms (ESP) products inherently last longer than conventional batteries, with lower maintenance costs and fewer thermal management concerns.

Solutions exist for the following applications

  • Commercial and Industrial
  • Utilities
  • Telecom
  • Residential

Whether you are powering a cell tower or large industrial complex, Imergy has a simple, reliable and cost-effective energy storage solution to meet your requirements.
