How is energy stored in Australia?

Currently storage of electrical energy in Australia consists of a small number of pumped hydroelectric facilities and grid-scale batteries, and a diversity of battery storage systems at small scale, used mainly for backup. To balance energy use across the Australian economy, heat and fuel (chemical energy) storage are also required.

How will energy storage improve Australia's energy resilience?

It will develop storage at varying scales, using low environmental impact materials to expand Australia’s energy resilience. Energy storage is developing at a rapid speed, as it keeps up with advances in fuel technology. New management systems are needed to incorporate increasing proportions of renewable energy into the current power network.

Are energy storage projects progressing in Australia?

Since the release of the report three years ago, there has been a range of energy storage projects progressed in Australia. For example, in 2017, a large-scale energy storage facility in South Australia was constructed using Tesla’s lithium-ion battery system, with excellent results.

Is energy storage the next big change in Australia's electricity systems?

Energy storage is seen by many as the next big change required in Australia’s electricity systems. Storage can solve challenges that range from smoothing the intermittency of renewable generation to providing power quality support, and managing peak demand for consumers. For further details, refer to Appendix 1 of the full report.

Which energy storage technology is best for Australia's energy needs?

The CEC said emerging LDES technologies coupled with the energy storage systems in place, would be the best suite to appropriately manage Australia’s needs. In March this year, the ARENA held an Insights Forum which covered energy storage and technologies that can bring system security to the grid.

What are Australia's energy storage options?

The then most cost-effective storage options anticipated in 2030 were pumped hydro energy storage (PHES), lithium-ion batteries and zinc bromine batteries. Australia’s abundance of raw materials for batteries and our high level of relevant R&D make energy storage a significant opportunity for industry growth and job creation.
