海洋运输部门负责消耗大量降解燃料油，是全球变暖和空气污染的主要贡献者之一。这些影响是美国和世界各地大量过早死亡的原因。由国际海事组织（海事组织）执行的被称为《2008年防污公约附件六修正案》的国际法规对海洋船舶的排放施加了越来越严格的限制。生物柴油是一种环保、可再生、清洁、低碳的燃料，被认为是最适合船舶使用的替代燃料。然而，在水上运输中推广使用生物柴油被认为是一个比在陆地应用中更成功的发展更大的挑战。在这项研究中，主要的障碍，以促进生物柴油混合物在海上运输。提出了克服这些障碍的策略，包括在各种代表性类型的船舶上对生物柴油混合物进行全面的现场测试，建立船用级生物柴油规范，通过降低其制造成本来提高船用级生物柴油的价格竞争力，提供减税，免税和政府补贴，增加生物柴油在船舶应用中的使用量，在燃料供给系统和储罐中采用相容的弹性体和金属材料，采用适合改善生物柴油混合物低温流动性的方法或技术，提高精制甘油的附加值。这些策略的有效应用将使生物柴油在海洋应用中得到更广泛的应用，大幅减少船舶排放，改善全球空气质量，保护生态环境，提高人民健康水平。
The marine transportation sector, responsible for consuming a large amount of degraded fuel oil, is one of the major contributors to global warming and air pollution. These effects are responsible for a large number of premature deaths in the US and throughout the world. The international regulation known as the 2008 MARPOL Annex VI Amendment, which is enforced by the International Maritime Organization (IMO), has imposed progressively more stringent limits on emissions from marine vessels. Biodiesel, an environmentally friendly, renewable, clean, and low-carbon fuel, is regarded as the most appropriate alternative fuel for marine vessels. However, the promotion of biodiesel use in water-borne transportation is considered to be a bigger challenge than its more successful development in land-based applications. The major obstacles to promoting biodiesel blends in marine transportation are examined in this study. The strategies proposed to overcome these obstacles include the comprehensive field testing of the biodiesel blends in marine vessels of various representative types, establishing a marine-grade biodiesel specification, increasing the price competitiveness of marine-grade biodiesel by reducing its manufacturing costs, providing tax cuts, exemptions, and government subsidies, increasing the amount of biodiesel use in marine applications, adopting compatible elastomers and metallic materials in fuel feeding systems and storage tanks, applying approaches or technologies suitable for improving the low-temperature fluidity of biodiesel blends, and increasing the added value of purified glycerol. The effective application of these strategies will enable the more widespread use of biodiesel in marine applications, significantly reducing emissions from ships, improving global air quality, protecting the ecological environment and improving people’s health.
