Abstract

Peningkatan emisi karbon akibat penggunaan bahan bakar fosil menjadi penyebab utama perubahan iklim global. Salah satu upaya dekarbonisasi industri kimia adalah melalui produksi green ammonia yang tidak menghasilkan emisi CO2. Pada perancangan ini, green ammonia diproduksi menggunakan green hydrogen dari proses elektrolisis air dengan teknologi Polymer Electrolyte Membrane Water Electrolyzer (PEM-WE) serta nitrogen yang diperoleh dari PT Linde melalui air separation unit bertenaga listrik bersih. Pemilihan teknologi PEM-WE dilakukan karena mampu menghasilkan hidrogen dengan kemurnian tinggi dan efisiensi konversi besar. Proses sintesis amonia dilakukan melalui reaksi Haber–Bosch pada tekanan dan suhu tinggi untuk membentuk produk tanpa emisi karbon. Berdasarkan analisis ekonomi, diperoleh nilai CAPEX sebesar Rp 50 miliar, OPEX sebesar Rp 9 miliar per tahun, NPV sebesar –Rp 40 miliar, dan waktu pengembalian modal selama 14 tahun. Hasil ini menunjukkan bahwa pabrik belum layak secara ekonomi pada kondisi saat ini, namun secara lingkungan memiliki potensi besar dalam mendukung target Net Zero Emission 2060 sebagai alternatif produksi amonia berkelanjutan di Indonesia. Selain itu, pabrik ini tetap memiliki peluang besar di masa depan seiring meningkatnya nilai pasar global green ammonia dan kebijakan internasional yang semakin mengarah pada implementasi green processes untuk mencapai dekarbonisasi penuh di sektor industri.

The increase in carbon emissions from fossil fuel usage is one of the main causes of global climate change. One effective decarbonization effort in the chemical industry is the production of green ammonia, which generates no CO₂ emissions. In this design, green ammonia is produced using green hydrogen obtained through water electrolysis with Polymer Electrolyte Membrane Water Electrolyzer (PEM-WE) technology integrated with solar energy, while nitrogen is supplied by PT Linde through a clean electricity-powered air separation unit. The PEM-WE technology is selected for its high hydrogen purity and high conversion efficiency. Ammonia synthesis is carried out through the Haber–Bosch process under high pressure and temperature to form ammonia without carbon emissions. Based on the economic analysis, the plant requires a CAPEX of Rp 50 billion and an OPEX of Rp 9 billion per year, resulting in an NPV of –Rp 40 billion and a payback period of 14 years. These results indicate that the plant is not yet economically feasible under current conditions, but it has significant environmental potential to support Indonesia’s Net Zero Emission 2060 target as a sustainable alternative for ammonia production. Furthermore, this plant holds a strong future potential in the global market as many countries and international policies are increasingly shifting toward green processes to achieve full decarbonization across industrial sectors.
