Stationary Energy Storage

The rapid growth and large-scale integration of renewable energy presents both opportunities and challenges.

Renewable energy produced by photovoltaic (PV) panels or wind turbines is inherently variable. This variability is a major challenge for electricity providers trying to integrate renewable generation into the electricity grid.

To operate reliably and be stable, grids need to continuously balance supply and demand – a task complicated by the intermittency of renewable energy. UltraBattery® energy storage technology offers a solution that can efficiently deliver smooth and predictable power to the grid.

Ecoult has a trial wind smoothing project running at Hampton Wind Farm (New South Wales, Australia)

UltraBattery’s® ability to store energy and access it quickly allows it to control the ramp rates of renewable energy output before presenting it to the grid. It also stores energy for later use in times of unfavourable weather conditions or peak demand, making renewable energy reliable and enabling to adjust their power output on demand.
With its high cycle life, high conversion efficiency, low operating costs and recyclability, UltraBattery® therefore offers an economical, safe and environmentally sound solution for megawatt (MW) to kilowatt (kW)-scale stationary energy storage applications.
The services provided by UltraBattery® include:

  • grid ancillary services
  • smoothing the intermittent signal of solar and wind energy
  • energy shifting (storing energy for later use)
  • diesel efficiency optimization on standalone power systems.

UltraBattery® also provides energy storage solutions for remote microgrid applications and uninterruptible power supply (UPS) as well as multi-purpose backup for data centers, enabling conventional UPS services to be combined with revenue-generating and/or cost-saving functions such as demand management or peak shaving.

UltraBattery® can:

  • smooth the intermittency of renewable energy
  • control ramp rates of renewable energy output
  • provide grid ancillary services
  • shift energy by storing it for later use
  • improve diesel generator efficiencies.
