Cost-effective electricity storage for residential and commercial renewable energy installations has moved a step closer following the Australian Government’s backing of a pilot project featuring the Ecoult Deka Ultrabattery technology.

Sydney, Australia – 20 March, 2013. Australian energy storage company Ecoult has been awarded Australian Government funding through the Australian Renewable Energy Agency (ARENA) to conduct small/mid-sized storage project development using Deka UltraBattery technology to deliver cost effective storage solutions for homes and businesses in Australia and around the world.

This pilot will develop a battery storage system prototype for three types of deficit charge/distributed energy applications:

  • Off-grid renewable power solutions (Remote Area Power Supply);
  • Distributed grid connected storage to support voltage and power fluctuations that arise where there is dense concentration of small roof-top solar installations in residential areas; and
  • Hybrid generation (such as diesel plus renewables) to improve fuel efficiencies.

Ecoult CEO John Wood said the ARENA grant was a strong vote of confidence in the Australian-invented technology.

“Ecoult has already demonstrated the success of the Deka UltraBattery technology in MW scale applications in a range of field conditions,” Mr Wood said.

“We are now in the process of extending our products and solutions from MW-scale to commercial and residential applications. Our objective is to reduce the cost of energy storage applications and boost the competitiveness of small-scale renewable energy sources such as roof-top solar panels.

“This backing from the Australian Government will help us continue our work in enabling affordable and effective integration of renewable energy into the Australian grid as well as in remote, off-grid applications.

The pilot project will extend the successful collaboration between Ecoult, its US-based parent company East Penn Manufacturing and the Commonwealth Scientific and Industrial Research Organisation (CSIRO).

Research partner CSIRO, which originally invented the Deka UltraBattery technology, will also play an important role in this pilot project, developing intelligent algorithms that improve the integration of Deka Ultrabattery units with the Solar PV panels and increase the value derived from each kWh of energy storage.
