• As Australia shifts to 100% renewable energy, long-duration storage solutions are vital for managing the imbalance between excess solar and wind energy during low demand and shortages during peak demand times.
• Hydrostor’s Silver City Energy Project in Broken Hill uses excess energy by compressing air underground, which can be converted back to electricity when required.
• Implementing large-scale long-duration storage could lead to substantial reductions in electricity costs, improving grid flexibility and resilience while minimizing the need for costly transmission infrastructure. Australia is actively developing various storage technologies, such as compressed air and concentrated solar thermal systems, to significantly boost energy storage capacity and facilitate the transition to a renewable-powered grid.
