This article proposes a calculation methodology that starts from the demand calculation to supply a fleet bus with renewable hydrogen based on the electrolysis process until the energetic, economic, and environmental analyses, involving all the processes of the productive chair. Also considering the dynamic behaviour of the following hydrogen processes: production, storage, and use. The simplified scheme of the proposed system configuration to be studied consists of the use of alternative and renewable sources of energy (solar-wind-biogas) to generate electrical energy in order to produce hydrogen from electrolysis of the water, which is stored in its gaseous state and subsequently redirected to a filling station to be used as vehicle fuel in buses. The results show that to feed one bus the hybrid system generates an average of 78,110 kWh/month with an installed capacity of 1101.905 kW, producing 1209.90 kgH₂/month through the electrolysis process from water. The results also show a range of electricity generation costs between 1.130 and 0.123 US$/kWh and H₂ production between 0.963 and 0.110 US$/kWh. Concluding that the application of renewable energies to produce hydrogen and electricity for the public transport sector is an attractive alternative in the future throughout the country, because the proposed system is technically, economically and ecologically viable.

本文提出了一种计算方法，该方法从需求计算开始，以电解过程为基础，向车队客车提供可再生氢，直到进行涉及生产椅子的所有过程的能量，经济和环境分析。还应考虑以下氢过程的动态行为：生产，储存和使用。将要研究的拟议系统配置的简化方案包括使用替代性和可再生能源（太阳能-风-沼气）来产生电能，以便从电解水中产生氢，并将其存储在气态中状态，然后重定向到加油站，以用作公共汽车中的车辆燃料。结果表明，混合动力系统向一辆公交车供电时，平均产生了78辆，₂ /月通过水电解过程。结果还显示，发电成本的范围介于1.130和0.123美元/千瓦时之间，H _2的生产成本介于0.963和0.110美元/千瓦时之间。结论是，由于拟议中的系统在技术，经济和生态上都是可行的，因此在全国范围内，将可再生能源用于为公共交通部门生产氢气和电力是一种有吸引力的选择。
