description "This thesis evaluates the technical, economic and environmental performance of a hydrogen fueled hybrid bus, which uses an internal combustion engine as a power unit. Results are compared to those of a conventional diesel bus and to those of two commercially available hydrogen fuel cell buses. The performance of the different vehicles, under real driving conditions, is evaluated using validated models of these on the Autonomie simulation platform. On the other hand, the life-cycle GHG emissions of the buses are estimated with hydrogen being produced from different primary sources. Whilst the first scenario assumes that hydrogen is produced from natural gas via steam methane reforming, the other three assumes electrolytic production using different electricity production mixes. Finally the total cost of ownership of each hybrid bus is calculated and compared to that of the conventional bus. Results show that all hydrogen buses have a considerable lower energy consumption than that of the conventional vehicle. This is manly due to the use of the hybrid powertrain architecture. When comparing the different hydrogen buses, as expected, the fuel cell vehicles result in a higher efficiency than the internal combustion engine vehicles, but in a considerable higher cost, making the use of internal combustion engines a more cost effective way to reduce GHG emissions. The life cycle emission analysis shows that the environmental performance of all hydrogen vehicles is highly dependent on the carbon intensity of the hydrogen production. Overall, whilst fuel cells are more efficient than ICEs, the considerable lower cost of ICEs makes the H2ICE hybrid bus a more cost effective way of reducing GHG emissions."

"En esta tesis se analiza el rendimiento técnico, económico y ambiental de un bus híbrido alimentado a hidrógeno, que utiliza un motor de combustión interna (MCI) como unidad de potencia. Los resultados se comparan con los de un bus diesel convencional y con los de dos buses de celdas de combustible de hidrógeno disponibles comercialmente. El rendimiento de los mismos es evaluado con modelos computacionales utilizando la plataforma de simulación Autonomie. Dichos modelos son validados con información disponible en la literatura con ciclos de manejo reales. Por otro lado, las emisiones de GEI (Gases de Efecto Invernadero) del ciclo de vida de los buses son estimadas y se proponen diferentes escenarios según el origen del hidrógeno utilizado como combustible. Se analizan cuatro escenarios: en el primero se asume que el hidrógeno es producido mediante el reformado de vapor-metano y en los tres restantes se asume que es producido mediante electrólisis de agua utilizando energía eléctrica de la red con diferentes intensidades de carbono. Finalmente se calcula el costo de vida total de cada bus hibrido y se lo compara con el del bus convencional. Los resultados muestran que los buses a hidrógeno analizados tienen un consumo de energía sensiblemente menor que el de un bus convencional; esto se debe principalmente a la presencia de la arquitectura híbrida. Los buses híbridos con celda de combustible presentan una eficiencia global mayor que la del bus con MCI pero con un costo de vida total considerablemente mayor. Este resultado presenta al uso de MCI a hidrógeno como una alternativa económica para reducir los GEI. El análisis medioambiental muestra que el desempeño de los buses a hidrógeno es altamente dependiente de la intensidad de carbono de la red eléctrica considerada. Como conclusión, si bien las celdas de combustible son más eficientes que los MCI, el costo considerablemente menor de los MCI hace que el bus híbrido H2ICE sea una forma más económica de reducir las emisiones de GEI."
