@phdthesis{10902/24342, year = {2022}, month = {3}, url = {http://hdl.handle.net/10902/24342}, abstract = {RESUMEN Los combustibles bajos en carbono son clave para la transición hacia un sistema energético sostenible con menos emisiones contaminantes y menos dependiente de los combustibles fósiles. El hidrógeno como vector energético permite una amplia implementación de las fuentes de energía renovables, con una generación de energía limpia más distribuida en las diferentes regiones del mundo. Además, el hidrógeno puede utilizarse en muchos sectores, como el marítimo, con una importante contribución al transporte de mercancías y pasajeros. Asimismo, hay corrientes residuales industriales con un elevado porcentaje de hidrógeno y alto contenido energético, permitiendo su recuperación con motores de combustión interna, una tecnología empleada mundialmente. La primera parte de esta tesis se enfoca en el análisis de un sistema energético europeo en 2050 basado en hidrógeno orientado a barcos, mientras que en la segunda parte se realiza el estudio del gas de coque en un motor, tanto experimentalmente como en un modelo CFD.}, abstract = {ABSTRACT Low carbon fuels are key to the transition to a sustainable energy system with lower pollutant emissions and less dependence on fossil fuels. Hydrogen as an energy vector allows a wide implementation of renewable energy sources, with a more distributed clean energy generation across the world. In addition, hydrogen can be used in many sectors, such as the maritime sector, with an important contribution to freight and passengers transport. Likewise, there are industrial waste streams with a high percentage of hydrogen and high energy content, allowing its recovery with internal combustion engines, a worldwide deployed technology. The first part of this thesis focuses on the analysis of a European energy system in 2050 based on hydrogen oriented to ships, while in the second part the study of coke oven gas in an engine is carried out, both experimentally and in a CFD model.}, organization = {This thesis has been financially supported by the European Regional Development Fund within the framework of the Interreg Atlantic Program through the project “HYLANTIC” – EAPA_204/2016 and within the framework of the Interreg SUDOE Program through the project PEMFC-SUDOE (SOE1/P1/E0293 – INTERREG SUDOE/FEDER, UE), “Energy Sustainability at the SUDOE Region: Red PEMFC-SUDOE”.
