📄 Abstract（原文）
Abstract Nepal’s heavy-duty vehicle fleet relies entirely on imported fossil fuels, posing significant environmental risks due to high particulate matter (PM) emissions. Battery-powered alternatives are unsuitable for large fleets due to trade-offs between range and vehicle weight, which is not an issue for hydrogen-powered fuel cell electric vehicles (FCVs). Shifting to hydrogen fuel offers a promising solution for sustainable, emission-free heavy-duty vehicle operation. Fuel cell buses (FCBs) represent a transformative step in transportation, prioritizing environmental protection, decarbonization, and achieving net-zero carbon emissions by 2045. This paper reviews the critical components for developing an on-site hydrogen refueling station (OHRS). It analyzes the power requirements of vehicles operating on inclined roads based on vehicle modeling. By studying existing diesel buses on the route, the specifications needed for FCBs are determined. It involves Excel-based calculations of fuel demand, vehicle drive cycle modeling, infrastructure assessment, and capacity determination for a fleet of ten hydrogen buses. The analysis reveals that the maximum tractive power required is 119.85 kW, with buses averaging a velocity of 6.8 m/s, reaching a maximum of 20.75 m/s, and achieving a maximum acceleration of 0.96 m/s 2 . The average motor power required is 13.09 kW, with a maximum of 151.48 kW. Each bus requires 8 kg of hydrogen per day, necessitating an OHRS capable of producing 80 kg per day for a fleet of 10 buses. Consequently, the sizing of components such as the electrolyzer, compressor, storage, and dispenser is dictated by a hydrogen production flow rate of 4 kg per hour. This study provides a comprehensive framework for implementing and operationalizing OHRS to support the deployment of FCBs in heavy-duty transportation.
