US-based flow battery developer Imergy Power Systems (Imergy), known as Deeya Energy, has introduced a vanadium flow battery that costs $300/kWh.
According to Imergy, the 50kW battery comes with a minimum 20-year cycle life and can store up to 200kWh of electricity. The storage duration can be extended by increasing electrolyte concentration and volume. The ESP30 battery can be used at up to 131°F (55°C).
The Silicon Valley startup claimed that the use of recycled vanadium electrolytes from mining and power combustion industries as well as environmental waste lowers the cost of the product from $500 to $300/kWh.
The battery is designed for peak shaving, demand response, energy shifting, renewable energy firming, and microgrid or back-up power.
“The additional power capability and capacity of the new ESP30 series makes this battery one of the lowest cost storage options for solar arrays, wind turbines, and behind-the-meter grid applications,” said Bill Watkins, CEO of Imergy.
Imergy was founded 10 years ago as Deeya Energy. Since then, the company researched and developed its flow battery, backed by $100m in funding. Imergy plans to launch a flow battery that can store 1MWh of electricity by next year.
