‘Australian first’ compressed CO2 battery project takes shape

Victoria's State Electricity Commission (SEC) is partnering with Energy Dome to deploy a 10-hour duration compressed CO2 battery energy storage system near Morwell in the Latrobe Valley, marking Victoria's first long-duration energy storage facility and Australia's first commercial compressed CO2 battery. This technology aims to ensure around-the-clock reliability of supply for renewable energy generation from wind and solar, supporting Victoria's transition to clean energy and helping meet its 2030 clean energy targets. Additionally, stakeholder and community consultation has begun for the new SEC Energy Works energy innovation precinct in the Latrobe Valley, which will focus on developing new energy infrastructure and storage technologies to further support the state's future energy system. Projects at SEC Energy Works will contribute to the government-owned renewable energy company's portfolio, including the Melbourne Renewable Energy Hub and the SEC Renewable Energy Park, emphasizing the importance of energy innovation, early investment, and confidence building for new energy technologies.
