Energy storage is important to the adoption of clean energy

Energy Storage Company Imergy Power Systems ( Solar Thermal Magazine) – Imergy Power Systems, a pioneer in advanced storage systems, this week announced that Energy Research Systems has signed a purchase order for four ESP5 vanadium flow batteries, marking the first orders for Imergy in the United States.

The ESP5 is capable of 5 kilowatts (kW) of capacity and can store up to 30 kilowatt hours (kWh) of electricity.

Currently, over 200 Imergy vanadium flow batteries are installed worldwide, with customers ranging from residential users to remote off-grid commercial users to institutional microgrids.

 

The four ESP5s ordered by Energy Research Systems will be used by:

  • Two residential customers, who are installing the ESP5 vanadium flow batteries in conjunction with new off-grid solar power systems.
  • One microgrid customer, who is installing the ESP5 vanadium flow battery as it works to develop an off-grid microgrid to test various solar, storage, hydrogen production and other advanced energy technologies.
  • One institutional customer, a technical school’s science center, recipient of both LEED™ Platinum and Living Building Challenge™ certifications. Their ESP5 vanadium flow battery will work in conjunction with a solar power system at the facility as the school evaluates how to take their entire campus off-grid using renewable energy and energy storage technologies.

With high energy costs, a stressed grid and ample renewable resources, Hawaii has been a leader in installing advanced energy technologies as it seeks to build a clean power grid for the 21st century.

“As these customers demonstrate, the combination of solar power systems and Imergy vanadium flow batteries are a cost effective solution for areas with high electricity prices or limited grid capabilities,” said Dr. Herve Mazzocco, Director of Business Development for Imergy Power Systems.

From residential island homes to advanced energy technology power testing facilities, a rapidly growing number of customers around the world are choosing to install Imergy vanadium flow batteries.

Vanadium Flow Batteries Imergy specializes in a proprietary, vanadium flow battery system, the most cost-effective energy storage technology available today. Flow batteries essentially store electricity 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 without impact on its lifespan. Integrated power electronics manage the charging and discharging processes, but the unique architecture allows the system to be scaled up in size by simply increasing the electrolyte volumes. The Imergy product inherently lasts longer than conventional batteries, with lower maintenance costs and fewer thermal management concerns.

This year, Imergy unveiled how it can produce vanadium-based storage systems with low-grade vanadium from mining slag and other environmental waste. By extracting vanadium from slag, Imergy will lower the cost of obtaining and processing vanadium—the principal active ingredient in many flow battery electrolytes–by 40% relative to competitors. As a result of this technology and other developments, Imergy will be able to lower the cost of its turnkey flow battery solutions (including PCS) from $500 a kilowatt hour, already an industry benchmark, to under $300 per kilowatt hour.
