Moomba Gas Plant CCS

Located at the Moomba Gas Plant in South Australia’s northeast, the Moomba Carbon Capture and Storage project is Australia’s first large-scale onshore hub for the capture and geological storage of carbon dioxide (CO2). The project is designed to store up to 1.7 million tonnes of CO2 per year, depending on availability of CO2, with a lifecycle cost of less than US$30 per tonne of CO2, it is one of the lowest-cost CCS projects globally. The Moomba CCS project utilizes depleted oil and gas reservoirs for CO2 storage. These reservoirs are ideal storage sites and have previously stored hydrocarbons for tens of millions of years. In October 2024, Santos announced that the Moomba CCS project was operational and had commenced capturing, injecting and storing CO2 in the Cooper Basin, following a successful commissioning process and ramp-up. Moomba CCS is now fully operational and is delivering real emissions reduction for South Australia and Australia.
