Abstract

Perubahan iklim akibat meningkatnya emisi karbon dioksida (CO₂) mendorong Indonesia untuk menurunkan emisi melalui komitmen Nationally Determined Contribution (NDC) dan target Net Zero Emission (NZE). Sektor ketenagalistrikan, khususnya PLTU batu bara, merupakan salah satu penyumbang emisi CO₂ terbesar sehingga penerapan Carbon Capture and Storage (CCS) menjadi salah satu strategi mitigasi yang memerlukan sistem distribusi CO₂ yang efisien. Penelitian ini bertujuan merancang dan mengevaluasi sistem distribusi CO₂ dari PLTU Tanjung Jati B, PLTU Rembang, dan PLTU Tanjung Awar-Awar menuju Reservoir North East Java dengan mempertimbangkan aspek operasional dan keekonomian. Potensi emisi CO₂ dari ketiga PLTU mencapai 28.209.369 ton CO₂/tahun. Penelitian ini menggunakan tiga skenario efisiensi penangkapan sebesar 50%, 70%, dan 90%. Pemodelan dilakukan menggunakan pendekatan simulasi diskrit untuk membandingkan dua skenario distribusi, yaitu Skenario 1 dengan pola single trip pada seluruh PLTU dan Skenario 2 dengan kombinasi single trip untuk PLTU Tanjung Jati B serta point to point untuk PLTU Rembang dan PLTU Tanjung Awar-Awar, menggunakan variasi kapasitas kapal sebesar 51.000 m³, 84.000 m³, dan 91.000 m³. Hasil simulasi menunjukkan bahwa kedua skenario mampu mendistribusikan CO₂ menuju platform injeksi, namun Skenario 2 memberikan kinerja operasional yang lebih baik dengan biaya transportasi kapal yang lebih rendah pada seluruh tingkat efisiensi penangkapan. Analisis keekonomian menunjukkan bahwa implementasi CCS meningkatkan nilai Levelized Cost of Electricity (LCOE) dan tarif listrik seiring meningkatnya efisiensi penangkapan CO₂. Pada efisiensi penangkapan 90%, nilai LCOE mencapai Rp444,90/kWh dengan kenaikan tarif listrik sebesar 32,96%, sedangkan pada efisiensi 50% nilai LCOE sebesar Rp399,20/kWh dengan kenaikan tarif listrik sebesar 29,57%. Hasil penelitian menunjukkan bahwa kombinasi pola single trip dan point to point pada Skenario 2 merupakan alternatif distribusi CO₂ yang paling efisien untuk mendukung implementasi CCS pada sektor pembangkitan listrik.

Climate change driven by increasing carbon dioxide (CO₂) emissions has encouraged Indonesia to reduce greenhouse gas emissions through its Nationally Determined Contribution (NDC) commitment and Net Zero Emissions (NZE) target. The power generation sector, particularly coal-fired power plants, is one of the largest contributors to CO₂ emissions. Therefore, the implementation of Carbon Capture and Storage (CCS) has become an important mitigation strategy, requiring an efficient CO₂ transportation system to ensure its successful deployment. This study aims to design and evaluate a CO₂ distribution system from Tanjung Jati B, Rembang, and Tanjung Awar-Awar coal-fired power plants to the North East Java reservoir by considering both operational and economic aspects. The total CO₂ emissions generated by these three power plants reach 28.21 million tons per year, with CO₂ capture efficiencies of 50%, 70%, and 90% evaluated in this study. The distribution system was modeled using a discrete simulation approach to compare two distribution scenarios: Scenario 1, which applies a single trip pattern for all power plants, and Scenario 2, which combines a single trip pattern for Tanjung Jati B with a point to point pattern for Rembang and Tanjung Awar-Awar, using carrier capacities of 51,000 m³, 84,000 m³, and 91,000 m³. The simulation results indicate that both scenarios are capable of transporting CO₂ to the injection platform; however, Scenario 2 demonstrates superior operational performance by achieving lower marine transportation costs under all capture-efficiency levels. The economic analysis further reveals that implementing CCS increases the Levelized Cost of Electricity (LCOE) and electricity tariffs as the CO₂ capture efficiency increases. At a 90% capture efficiency, the LCOE reaches IDR 444.90/kWh, resulting in an electricity tariff increase of 32.96%, while at a 50% capture efficiency, the LCOE is IDR 399.20/kWh, corresponding to a 29.57% tariff increase. Overall, the results demonstrate that the combination of Single Trip and Point-to-Point distribution patterns in Scenario 2 provides the most efficient CO₂ transportation system, supporting the implementation of CCS in Indonesia's coal-fired power generation sector.
