Abstract

Peningkatan emisi karbon dioksida (CO₂) akibat aktivitas industri merupakan salah satu faktor utama yang berkontribusi terhadap perubahan iklim global. Untuk mencapai target Net Zero Emission, Indonesia perlu mengembangkan teknologi mitigasi emisi karbon yang efektif dan berkelanjutan. Indonesia memiliki potensi besar dalam penerapan teknologi Carbon Capture and Storage (CCS). Penelitian ini bertujuan untuk melakukan pemodelan dan simulasi injeksi CO₂ ke dalam media batuan berpori, mengevaluasi pengaruh kondisi operasional terhadap kapasitas penyimpanan CO₂ serta menghitung kapsitas penyimpanan CO₂, pada formasi batuan berpori di Indonesia. Metodologi penelitian meliputi pemodelan numerik menggunakan ANSYS Fluent. Karakterisasi sifat batuan dilakukan menggunakan X-Ray Diffraction (XRD) sebagai dasar penentuan parameter batuan dalam simulasi. Analisis optimasi dilakukan menggunakan pendekatan Response Surface Methodology (RSM) dengan rancangan Central Composite Design (CCD). Hasil validasi model terhadap data referensi menunjukkan error rata-rata sebesar 3,08%, yang menegaskan bahwa model mampu merepresentasikan dinamika aliran dan perpindahan massa CO₂ dengan baik. Analisis kuantitatif menunjukkan bahwa interaksi antara laju injeksi dan tekanan operasi merupakan faktor paling dominan yang memengaruhi karakteristik aliran CO₂ dan efisiensi mekanisme trapping. Berdasarkan hasil simulasi, kapasitas penyimpanan CO₂ yang diperoleh mencapai 27,6 GtCO₂ pada wilayah Northeast Java Basin, yang mengindikasikan potensi signifikan kawasan tersebut sebagai kandidat lokasi penyimpanan CO₂ dalam skala besar. Hasil penelitian ini memberikan dasar bagi pengembangan dan implementasi teknologi CCS di Indonesia sebagai strategi mitigasi emisi karbon jangka panjang.

The increase in carbon dioxide (CO₂ ) emissions due to industrial activities is one of the main factors contributing to global climate change. To achieve the Net Zero Emission target, Indonesia needs to develop effective and sustainable carbon emission mitigation technologies. Indonesia has great potential in the application of Carbon Capture and Storage (CCS) technology. This study aims to model and simulate the injection of CO₂ into porous rock media, evaluate the influence of operational conditions on CO₂ storage capacity and calculate CO₂ storage capacity, in porous rock formations in Indonesia. The research methodology includes numerical modeling using ANSYS Fluent. Characterization of rock properties is carried out using X-Ray Diffraction (XRD) as the basis for determining rock parameters in the simulation. The optimization analysis was carried out using the Response Surface Methodology (RSM) approach with a Central Composite Design (CCD) design. The results of the model validation of the reference data showed an average error of 3.08%, which confirms that the model is able to represent the dynamics of CO₂ flow and mass transfer well. Quantitative analysis shows that the interaction between injection rate and operating pressure is the most dominant factor influencing the characteristics of CO₂ flow and the efficiency of the trapping mechanism. Based on the simulation results, the CO₂ storage capacity obtained reached 27.6 GtCO₂ in the Northeast Java Basin region, which indicates the significant potential of the area as a candidate for large-scale CO₂ storage locations. The results of this study provide a basis for the development and implementation of CCS technology in Indonesia as a long-term carbon emission mitigation strategy.
