摘要

由于越来越多的监管和部分船东社区承诺减少其对环境的影响,航运部门可能在未来几十年内经历燃料转型。如果航运业要按照国际海事组织2018年4月达成的协议和2015年《巴黎协定》限制其温室气体排放,使全球变暖保持在2°C以下,就需要在采用环保技术、运营措施和基于替代燃料的新推进形式方面采取紧急行动。虽然在过去十年中出现了一些关于旨在减少航运排放的操作和技术措施的研究,但对燃料转换的经济和环境影响的关注有限。本研究旨在分析可用于航运的替代燃料选择,并评估通过燃料转换可实现的减排。本文还提供了与这种燃料转换相关的成本的见解。通过基于现有替代燃料成本和可用性信息的模拟,本文表明使用替代燃料最多可以减少24%的温室气体排放。然而,这种减少可以在不同的成本水平上实现。为政策制定者和航运业提供了2050年的最佳船队组合指导。

Alternative Fuels for Shipping: Optimising Fleet Composition Under Environmental and Economic Constraints
The shipping sector is likely to go through a fuel transition in the coming decades as a result of the increasing regulation and the commitment of part of the ship-owning community to reduce its environmental impact. If shipping is to limit its greenhouse gas emissions so that global warming is maintained below 2°C as agreed by the IMO in April 2018 and in line with 2015 Paris Agreement, urgent action is needed in terms of environmentally friendly technologies uptake, operational measures and new forms of propulsion based on alternative fuels. While some research has appeared in the last decade on operational and technological measures aimed at reducing emissions for shipping, limited focus has been put on the economic and environmental impacts of a fuel shift. This research aims at analysing the alternative fuel options available for shipping and assess the emission reductions obtainable through a fuel shift. The paper also provides insights on the costs associated with such fuel transition. Through the development of a simulation based on existing information of alternative fuel costs and availability, the paper shows that a maximum of 24% greenhouse gas emission reduction can be achieved by using alternative fuels. Such reduction, however, can be obtained at varying cost levels. An optimal fleet mix is provided for 2050 as guidance for policy makers and the shipping sector.
