In October 2024, Santos achieved a transformational milestone with the delivery of the Moomba Carbon Capture and Storage (Moomba CCS) project, marking a very significant step in Santos’ three hub CCS strategy.  In its first year of operations Moomba CCS safely stored 1.3 million tonnes of CO2e.  In November 2025 Moomba CCS achieved another major milestone with the largest single issuance of Australian Carbon Credit Units (ACCUs) from the Clean Energy Regulator.  This paper provides a project update on Moomba CCS covering the first year of operations.
