Energy storage in Australia

What is energy storage? Energy storage secures and stabilises energy supply, and services and cross-links the electricity, gas, industrial and transport sectors. It works on and off the grid, in passenger and freight transportation, and in homes as ''behind the meter'' batteries and thermal stores or heat pump systems.
