Abstract

Indonesia berkomitmen mencapai Net Zero Emission (NZE) 2060 sehingga diperlukan pengembangan energi rendah karbon, salah satunya melalui produksi green hydrogen sebagai alternatif green hydrogen pada sektor industri. Studi ini bertujuan merancang pabrik hidrogen hijau melalui water electrolysis dengan kapasitas produksi 26.000 ton/tahun di Palembang, Sumatera Selatan. Teknologi produksi dipilih menggunakan metode Analytical Hierarchy Process (AHP), dengan Alkaline Water Electrolysis (AWE) terpilih karena memiliki tingkat kematangan teknologi tinggi, biaya investasi rendah, dan umur stack yang panjang. Air baku berasal dari Sungai Musi yang diolah melalui rangkaian water treatment berupa fine screening, koagulasi-flokulasi, ultrafiltrasi, reverse osmosis, dan ion exchange hingga memenuhi standar ASTM Type II untuk kebutuhan elektroliser. Produk hidrogen yang dihasilkan memiliki kemurnian ≥99,95% sesuai standar CGA G-5.3-2004 Type I-B, dengan oksigen sebagai produk samping yang dapat dimanfaatkan secara komersial. Berdasarkan hasil perancangan, kebutuhan energi listrik elektrolisis sebesar 167,344 MW dengan total kebutuhan listrik pabrik sebesar 177,29 MW. Evaluasi ekonomi menunjukkan total capital investment (TCI) sebesar Rp9,73 triliun dengan fixed capital investment (FCI) Rp8,76 triliun dan working capital investment (WCI) Rp978 miliar. Analisis kelayakan menghasilkan nilai NPV sebesar Rp374 miliar, IRR sebesar 8,9%, Pay Out Time (POT) ±9,1 tahun, Break Even Point (BEP) sebesar 36,36%, dan variabel yang paling berpengaruh terhadap nilai IRR adalah harga jual hidrogen. Berdasarkan aspek teknis, ekonomi, dan lingkungan, desain pabrik hidrogen hijau ini dinyatakan layak untuk didirikan.

Indonesia is committed to achieving Net Zero Emissions (NZE) by 2060, requiring the development of low-carbon energy sources, one of which is green hydrogen production as an alternative to conventional (grey) hydrogen in the industrial sector. This study aims to design a green hydrogen plant based on water electrolysis with a production capacity of 26,000 tons/year in Palembang, South Sumatra. The production technology was selected using the Analytical Hierarchy Process (AHP) method, with Alkaline Water Electrolysis (AWE) chosen for its high technology readiness level, low investment cost, and long stack lifetime. Raw water is sourced from the Musi River and treated through a series of water treatment processes, fine screening, coagulation-flocculation, ultrafiltration, reverse osmosis, and ion exchange to meet ASTM Type II standards for electrolyzer feedwater. The hydrogen product achieves a purity of $\ge$99.95%, complying with CGA G-5.3-2004 Type I-B standards, with oxygen produced as a commercially valuable byproduct. Based on the design results, the electrolysis electrical energy requirement is 167.38 MW, with a total plant electricity demand of 177.33 MW. Economic evaluation shows a total capital investment (TCI) of IDR 9.73 trillion, comprising a fixed capital investment (FCI) of IDR 8.76 trillion and a working capital investment (WCI) of IDR 973.36 billion. Feasibility analysis yields an NPV of IDR 374 billion, an IRR of 8.9%, a Pay Out Time (POT) of $\pm$9.1 years, a Break Even Point (BEP) of 36.36%, with hydrogen selling price identified as the variable most influential on IRR. Based on technical, economic, and environmental aspects, this green hydrogen plant design is deemed feasible for construction.
