Abstract

Amonia, dengan potensi pembakaran nol karbon, metanol, yang mudah ditangani dan kompatibel dengan infrastruktur yang ada, dan LNG, yang terkenal dengan kandungan energinya yang tinggi dan emisi yang rendah, semuanya dievaluasi menggunakan berbagai indikator kinerja. Temuan menunjukkan bahwa, meskipun LNG saat ini memimpin dalam hal efisiensi bahan bakar karena kepadatan energinya yang tinggi, amonia dan metanol memberikan manfaat jangka panjang yang cukup besar, terutama mengingat dampak lingkungan yang minimal dan skalabilitasnya di masa depan. LPG, yang terkenal dengan sifat pembakarannya yang bersih, juga menghadirkan alternatif yang layak dengan emisi CO2 dan partikulat yang lebih rendah. Studi ini memberikan data penting bagi operator kapal dan regulator untuk membuat keputusan tentang penggunaan bahan bakar alternatif dalam industri maritim.
Tujuan dari penelitian ini adalah untuk memberikan perbandingan komprehensif amonia, metanol, LPG, dan gas alam cair (LNG) sebagai bahan bakar alternatif pelayaran maritim, dengan fokus pada penghematan bahan bakar.

Ammonia, with its zero-carbon combustion potential, methanol, which is easy to handle and compatible with existing infrastructure, and LNG, which is known for its high energy content and low emissions, are all evaluated using a variety of performance indicators. The findings show that, while LNG presently leads in fuel efficiency due to its high energy density, ammonia, and methanol provide considerable long-term benefits, particularly given their minimal environmental effect and future scalability. LPG, known for its clean combustion properties, also presents a viable alternative with lower CO2 and particulate emissions. This study provides vital data for ship operators and regulators to make informed decisions about the use of alternative fuels in the maritime industry.
The purpose of the study is to provide a comprehensive comparison of ammonia, methanol, LPG, and liquefied natural gas (LNG) as alternative fuels for maritime shipping, with a focus on fuel economy.
