Seattle-based energy storage manufacturer UniEnergy Technologies (UET) has launched its grid-scale flowbattery system, Uni.System.
The Uni.System vanadium flow battery provides short and long duration buffering capabilities to integrate intermittent resources into the grid. The modular factory-integrated battery consists of five 20 feet standard containers providing 500kW of power for four hours, power up to 600kW and up to 2.2MWh of energy.
The Uni.System uses a new generation of vanadium electrolyte developed at Pacific Northwest National Laboratory, supported by the US Department of Energy’s Grid Storage Programme, with double energy density and a broader temperature range from -40C to 50C (-40F to 120F). “The Uni.System is fully containerized including for the first time at grid-scale integrated electrolyte tanks, field-proven large-scale stacks, and optimized controls and power electronics”, said UET President & CEO Gary Yang.
The impact of Hurricane Sandy on New York in 2012 and the demands placed on utilities by renewables and smart grids, show the need of resilient utilities. The Uni.System aims to meet these challenges in safety, reliability, 20-year system life and affordable upfront cost.
