For the short-medium term, new EU and national energy and climate plans agree on a strategy based on the combination of increasing shares of electric vehicles with the promotion of sustainable fuels, especially if produced from residual feedstock and routes with low or zero net carbon emission. Hydrogen stands out among these fuels for its unique properties. This work analyses the potential of using hydrogen in a dual-fuel, compression-ignition engine running with three diesel-like fuels (conventional fossil diesel, advanced biodiesel and hydrotreated vegetable oil-HVO) and different hydrogen energy substitution ratios. The results were confronted with conventional diesel operation, revealing that dual-fuel combustion with hydrogen demands higher EGR rates and more advance combustion, leading to a remarked reduction of NOx emission at the expense of a penalty in energy consumption due mainly to unburnt hydrogen and wall heat losses. Unreacted hydrogen was ameliorated at high load. At low load, the use of biodiesel dual combustion permitted higher hydrogen substitution ratios and higher efficiencies than diesel and HVO.Recientemente se ha avanzado hacia la descarbonización del transporte, responsable de una cuarta parte de las emisiones mundiales de dióxido de carbono. A corto y medio plazo, los nuevos planes energéticos y climáticos nacionales y de la UE coinciden en una estrategia basada en la combinación del aumento de la cuota de vehículos eléctricos con el fomento de combustibles sostenibles, especialmente si se producen a partir de materias primas residuales y rutas con baja o nula emisión neta de carbono. El hidrógeno destaca entre estos combustibles por sus propiedades únicas. En este trabajo se analiza el potencial del uso de hidrógeno en un motor dual de encendido por compresión que funciona con tres combustibles similares al diésel (diésel fósil convencional, biodiésel avanzado y aceite vegetal tratado con hidrógeno-HVO) y diferentes ratios de sustitución energética del hidrógeno. Los resultados se confrontaron con el funcionamiento con gasóleo convencional, revelando que la combustión dual con hidrógeno exige mayores tasas de EGR y una combustión más avanzada, lo que conduce a una notable reducción de la emisión de NOx a expensas de una penalización en el consumo de energía debida principalmente al hidrógeno no quemado y a las pérdidas de calor en la pared. El hidrógeno no reaccionado se mejoró a alta carga. A baja carga, el uso de la combustión dual con biodiésel permitía mayores ratios de sustitución del hidrógeno y eficiencias superiores a las del diésel y el HVO.Johnson Matthey Technology Review202320232023info:eu-repo/semantics/articleapplication/pdfapplication/pdfhttps://hdl.handle.net/10578/32464reponame:RUIdeRA.
