An increased concentration of CO2 leads to an abnormal acceleration of climate change. Consequently, to keep global temperatures below 2°C and strive to limit them to 1.5°C, the Paris Agreement was formed in 2015. Indonesia has taken a role by committing to reducing emissions through the development of Carbon Capture Utilization and Storage (CCUS) technology. Implementing CCS/CCUS faces significant cost challenges. Besides the cost issues, there is a lack of detailed information about the networks connecting CO2 sources and sinks (hubs) and limited data on CCUS optimization. Therefore, this study aims to propose the optimal hub network route between CO2 source and sink, determine technical aspect of CCUS hub network optimization, and assess the economic feasibility of CCUS hub network optimization in Handil and Bekapai Fields, East Kalimantan. This study on CCUS Hub Network Optimization involves creating a source-sink map and path using Google Earth, and selecting the shortest route using Python. For the technical aspect of analysis, it involves designing the pipeline (including pipe length, pipe ID, pipe thickness, and OD) and booster pump (including number of pump and power each pump). Author conduct the economic analysis by determining revenue and profit through a sensitivity analysis of carbon price and oil price parameters to achieved the desire IRR of 15%. The study shows that Handil field is suitable as a CO2 sink for CCUS project. To optimize the CCUS hub network between Handil field and five CO2 sources, 23 booster pumps are needed, with pipelines totaling 167.475 km. The base case economic analysis yields an IRR of only 4%. However, the project becomes viable, achieving an IRR of 15%, if the carbon price reaches $107.78 USD/MT.
