摘要

电动公交在减少温室气体排放、减少对化石燃料的依赖和应对气候变化方面至关重要。然而，向电动公交车的过渡需要一个全面的计划，以优化资源分配、技术选择、基础设施部署和组件规模。本研究开发了纯电动巴士（beb）和氢燃料电池巴士（hfcb）的系统配置优化模型，使所有相关成本（即资本和运营成本）最小化。这些模型在三种运行方案中优化了充电/加气站的组件规模、车队配置和能源/燃料管理系统：beb机会充电、beb夜间充电和电解驱动的hfcb夜间加油。结果表明，BEB机会制度是最经济可行的选择。与此同时，HFCB的成本（134.5%）和排放量（215.7%）都高于BEB过夜充电系统。敏感性分析表明，要在经济上与BEB系统竞争，需要大幅降低HFCB机组和电力成本。

Optimal configuration of hydrogen- and battery-based electric bus transit systems

Electric bus transit is crucial in reducing greenhouse gas (GHG) emissions, decreasing fossil fuel reliance, and combating climate change. However, the transition to electric-powered buses demands a comprehensive plan for optimal resource allocation, technology choice, infrastructure deployment, and component sizing. This study develops system configuration optimization models for battery electric buses (BEBs) and hydrogen fuel cell buses (HFCBs), minimizing all related costs (i.e., capital and operational costs). These models optimize component sizing of the charging/refueling stations, fleet configuration, and energy/fuel management system in three operational schemes: BEBs opportunity charging, BEBs overnight charging, and electrolysis-powered HFCBs overnight refueling. The results indicate that the BEB opportunity system is the most economically viable choice. Meanwhile, HFCB requires a higher cost (134.5%) and produces more emissions (215.7%) than the BEB overnight charging system. A sensitivity analysis indicates that a significant reduction in the HFCB unit and electricity costs is required to compete economically with BEB systems.

期刊介绍： The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc. The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
