Flow Batteries for Grid-Scale, Commercial and Industrial Energy Storage
Imergy Power Systems today introduced its new ESP250 series of vanadium flow batteries. Featuring an output power capability of 250kW, 1MWh of energy storage capacity and a modular design that supports linking of multiple batteries into a single Energy Storage Platform (ESP), the ESP250 provides utilities, renewable energy developers and commercial and industrial customers with a low-cost, high-performance energy storage solution for large-scale energy storage applications.
Potential applications for the ESP250 include peaker plant replacement, transmission and distribution investment deferral, renewables management, microgrid implementation or back-up power system delivery. Customers can also use the ESP250 for multiple applications, such as frequency regulation and peak shaving, thereby increasing their return on investment (ROI).
"With the introduction of the ESP250, Imergy has broadened its product portfolio to include a product for every major energy storage market segment and application," said Bill Watkins, CEO of Imergy Power Systems. "From demand response for individual buildings, to frequency regulation for the grid, Imergy has a product designed to meet the market's growing demand for low-cost, high performance energy storage."
The ESP250 modules measure approximately 12 meters (two stacked 40 foot shipping containers), with available energy ranging from 2 to 12 hours of output duration. ESP250 modules can be linked together to form Energy Storage Platforms capable of delivering megawatts of power and storing megawatt hours of energy. The system provides power security (can operate in full islanded mode) and power quality (with fast response time for seamless power source transitions, load transients, and photovoltaic system firming).
The ESP250 also incorporates fast charge capabilities and state-of-the-art controls and electronics, and can be remotely managed using secure Linux- and Windows-based integrated dispatch optimization software.
The ESP250 operates within a far wider temperature range than lithium ion or other storage solutions and is air-cooled. The storage duration can be extended by increasing electrolyte concentration and volume. Built in a modular fashion from replaceable components, the ESP250 has a lifetime that is effectively unlimited. Worldwide customer delivery of the ESP250 will begin in the summer of 2015.
