Abstract

Produksi amonia hijau merupakan salah satu upaya dekarbonisasi industri pupuk melalui pemanfaatan hidrogen hasil elektrolisis berbasis energi terbarukan. Tantangan utama implementasinya adalah tingginya kebutuhan energi listrik yang bersifat kontinu, sementara Pembangkit Listrik Tenaga Surya (PLTS) memiliki karakteristik intermiten sehingga memerlukan integrasi dengan sistem penyimpanan energi maupun jaringan listrik. Penelitian ini bertujuan untuk menganalisis kelayakan teknis dan ekonomi berbagai konfigurasi sistem penyediaan energi untuk produksi amonia hijau di kawasan industri pupuk Aceh Utara. Simulasi dan optimasi dilakukan menggunakan HOMER Pro dengan membandingkan empat skenario, yaitu PLN Grid, PV On-Grid, PV On-Grid dengan Battery Energy Storage System (BESS), dan PV Off-Grid. Parameter evaluasi meliputi Net Present Cost (NPC), Levelized Cost of Electricity (LCOE), Levelized Cost of Hydrogen (LCOH), dan Levelized Cost of Ammonia (LCOA). Hasil penelitian menunjukkan bahwa konfigurasi PV On-Grid merupakan alternatif paling optimal dengan nilai LCOH sebesar Rp105.222/kg H₂ dan LCOA sebesar Rp. 22.567.875/ton NH₃, serta memiliki keseimbangan terbaik antara biaya investasi, keandalan pasokan energi, dan pemanfaatan energi surya. Sebaliknya, konfigurasi PV Off-Grid menghasilkan biaya investasi dan NPC tertinggi akibat kebutuhan kapasitas PLTS dan sistem penyimpanan energi yang besar. Integrasi PLTS dengan jaringan PLN melalui skema Renewable Energy Certificate (REC) berpotensi menjadi solusi transisi yang layak untuk mendukung pengembangan amonia hijau dan pencapaian target dekarbonisasi industri di Indonesia.

Green ammonia production has emerged as a promising decarbonization strategy for the fertilizer industry by utilizing hydrogen produced through renewable energy-powered water electrolysis. However, its implementation is challenged by the continuous electricity demand of the ammonia synthesis process, whereas Solar Photovoltaic (PV) systems are inherently intermittent. Therefore, integrating PV systems with energy storage and the utility grid is essential to ensure reliable power supply. This study aims to evaluate the technical and economic feasibility of various energy supply configurations for green ammonia production in the fertilizer industrial area of North Aceh, Indonesia. System modeling and optimization were performed using HOMER Pro by comparing four scenarios: PLN Grid, PV On-Grid, PV On-Grid with Battery Energy Storage System (BESS), and PV Off-Grid. The evaluation was based on Net Present Cost (NPC), Levelized Cost of Electricity (LCOE), Levelized Cost of Hydrogen (LCOH), and Levelized Cost of Ammonia (LCOA). The results indicate that the PV On-Grid configuration is the most feasible option, achieving the lowest LCOH of RP. 105,222/kg H₂ and an LCOA of Rp. 22,567,875/t NH₃, while providing the best balance between investment cost, energy supply reliability, and solar energy utilization. In contrast, the PV Off-Grid configuration requires substantially larger PV and energy storage capacities, resulting in the highest capital investment and NPC. The integration of PV systems with the PLN grid through the Renewable Energy Certificate (REC) scheme represents a practical transition pathway for supporting green ammonia development and industrial decarbonization in Indonesia.
