This paper provides a comprehensive exploration of Liquefied Natural Gas (LNG) as a maritime fuel, addressing its technical, environmental, economic, and industry adoption aspects. The study reviews LNG's historical context, current status, and trends, emphasizing its potential to meet stringent emission standards. Technical considerations encompass LNG storage, handling, engine technologies, and safety. Environmental impacts, regulatory frameworks, and economic viability are analyzed, including case studies illustrating industry adoption. The paper scrutinizes LNG's role as a basic or transitional fuel, concluding that it serves as a transitional solution. Despite offering environmental benefits, challenges like methane slip and evolving regulatory targets position LNG as a temporary measure in the industry's shift toward zero-carbon fuels. The analysis contributes valuable insights for all the involved parties navigating the evolving landscape of sustainable shipping fuel alternatives, recognizing LNG's pivotal but temporary role in fostering environmentally conscious practices within the maritime sector.
