Indonesia benefits from advantageous geological conditions, providing basins with significant
potential for CO2 storage. Supported by Indonesia's Ministry of Energy and Mineral Resources
(MEMR) Regulation No. 2 of 2023, Indonesia aims to reduce gas emissions ambitious CCS (Carbon
Capture and Storage) and CCUS (Carbon Capture, Utilization, and Storage) projects. Previous studies
by LEMIGAS (2023), in South Sumatera Basin, the total CO2 storage is around 40 Giga tones in
saline aquifer, gas and oil reservoirs.
This study focuses on optimizing the CCS-CCUS hub network in the Jambi Area. By using Dijkstra's
algorithm and Mixed-Integer Linear Programming (MILP), the study aims to minimize transportation
costs, considering factors like the shortest path distance, CO2 injection rates, storage capacity, and
costs. The optimization results in source-sink pairs, pipeline designs, and booster pump designs, with
economic feasibility evaluated under the Gross Split fiscal scheme at a carbon price of $3.12/ton in
Indonesia.
Key findings include the selection of Betara Gas Plant as the source, with Gemah and Bajubang fields
as sinks. Amount of CO2 injected from Betara Gas plant is 84,000 tons/year (reduced to 49,560
tons/year for Gemah due to CO2 recycle) and 60,000 tons/year for Bajubang, these fields can only
accommodate 9% of the total annual CO2 emissions of 1,325,571 tons. Economically, at the current
Indonesia’s carbon price, the Betara Gas Plant-Gemah project has an NPV of 1.67 MMUSD, an IRR
of 11%, and a POT of 7.6 years, considering these values along with the MARR, the project isn’t
economically feasible to implement but has still reached its breakeven point. In contrast, Betara Gas
Plant-Bajubang remains economically unfeasible with significantly negative NPV and IRR values.
