UltraBattery® is an Australian technology, invented by the Commonwealth Industrial and Scientific Research Organization (CSIRO). CSIRO recognized that UltraBattery® provided a path to cost-effective, grid-scale energy storage solutions and in 2007 formed Ecoult to address this market.

The ABC report features one of Ecoult’s first demonstration projects at the Hampton wind farm in NSW, Australia, where Ecoult provided and integrated a MW scale wind power storage system using UltraBattery® technology. Ecoult demonstrated the ability to limit the 5-minute ramp rate to 1/10 of the raw output while applying wind power storage with a usable capacity (in kWhs) of 1/10 the rated output of the farm (in kW).
