摘要

对船舶利用岸上供电系统（OPS）和过渡到使用替代燃料的能源和峰值电力需求进行了可行性研究。研究以普利茅斯港为案例。港口有四种类型的船舶在运营，分别是滚装客船、油轮、散货船和普通货船。每种类型的船舶都选择了一艘具有代表性的船舶，以模拟船舶的平均载货能力和发动机功率。模拟了港口一年的实际运营情况，包括物料装卸设备和卡车。经计算，OPS 系统的峰值功率和年能源需求分别为 5.95 兆瓦和 7.1 千兆瓦时。实施 OPS 系统可节省 83.6% 的二氧化碳总量。对传统燃料和替代燃料的燃料体积进行了计算，液氢的体积约为传统燃料的 3.5 倍，而甲醇所需的质量和体积均小于氨和氢。

Port energy demand model for implementing onshore power supply and alternative fuels

A feasibility study was conducted on the energy and peak power demand of ships for utilising the Onshore Power Supply (OPS) and transitioning to using alternative fuels. The port of Plymouth was adopted as a case study. Four types of ships, Ro-Pax, Tanker, Bulk Carrier and General Cargo, were in operation at the port. A representative vessel was selected for each ship type to simulate the average ship’s cargo capacity and engine power. One year of real port operations, including material handling equipment and trucks, were simulated. The peak power and annual energy demand for the OPS system were calculated to be 5.95 MW and 7.1 GWh, respectively. Implementing an OPS system saved 83.6 % of total CO₂. Fuel volumes were calculated for conventional and alternative fuels, the volume of liquid hydrogen was around 3.5 times that of the conventional fuel, whereas methanol required less mass and volume than ammonia and hydrogen.

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
