Abstract: The International Energy Agency's Net Zero by 2050 Roadmap highlights the pivotal role of CCUS (Carbon Capture, Utilisation, and Storage) technologies in achieving global net-zero emissions. Worldwide plans project a substantial increase in CO2 capture volumes, with estimates rising from 40 Mt CO2 per year to 1.6 Gt CO2 by 2030 and further expanding to 7.6 Gt CO2 by 2050. In Southeast Asia, CCUS development is expected to grow from a limited base to 200 Mt or more by 2050, with around 95% of captured CO2 stored in permanent geological repositories. Identifying and determining CO2 storage resources are crucial for advancing CCUS. Indonesia offers promising opportunities for CCUS deployment due to its vast sedimentary basins suitable for CO2 storage, including oil and gas reservoirs and deep saline aquifers. This study assesses CO2 storage potential across Indonesia's sedimentary basins, estimating storage resources in saline aquifers and hydrocarbon reservoirs. Using advanced methodologies, it ranks basins in terms of CO2 storage suitability and integrates results into a GIS-based tool for visualisation. The study reveals Indonesia's significant CO2 storage potential, with estimated resources of 680.57 Gt in deep saline aquifers and 10.14 Gt in hydrocarbon fields. These resources are categorised as prospective and contingent storage resources, respectively, indicating substantial prospects for CCUS development. A GIS-based tool has been developed for visualising CO2 storage resources, positioning Indonesia as a key player in the regional CCUS landscape.
