ViZn Energy Systems wins flow battery system contract from INL


ViZn Energy Systems Inc. (ViZn), a leading provider of energy storage systems for microgrid and utility applications, has received an order for a 128 kW/320 kWh redox flow battery system based on its zinc-iron chemistry from Idaho National Laboratory (INL), part of the U.S. Department of Energy’s (DOE) complex of national laboratories.

INL will install the ViZn flow battery system as part of a microgrid research, development and demonstration testbed and is expected to be commissioned in the second quarter of 2016.

“We are seeing increasing interest in our flow batteries from both private and public organizations looking to initiate large-scale energy storage for various applications,” said ViZn president and CEO Ron Van Dell.

“Flow batteries, in general, are well suited for applications requiring large-scale, long-duration capabilities. Our systems, however, are particularly good at providing both energy services and power services in one system while utilizing a low cost, inherently safe alkaline chemistry.”

Kurt Myers, INL’s Clean Energy Market Area lead, added that the characteristics of the ViZn battery were of significant interest for island grids and microgrids that support various services in heavy-use and challenging environments, particularly for renewable energy integration challenges. “We are interested in the potential for lower cost energy storage systems, with 20-plus-year lifetimes and the ability to fulfill aggressive duty cycle requirements as well as long duration energy dispatch.”

ViZn said its zinc-iron redox flow battery was the only flow battery on the market with a non-toxic, non-flammable, non-explosive alkaline chemistry, allowing it to be deployed safely in densely-populated areas or adjacent to utilities and sub stations without the risks associated with other battery technologies. The company stressed that the battery’s chemical components were “globally abundant and inexpensive, providing favorable ROIs for utilities and commercial and industrial customers.”
