Abstract
[Resumen] La descarbonización del sector marítimo es clave para reducir las emi‐
siones contaminantes. Esto implica adaptar buques con la instalación de nuevos
equipos, desarrollar combustibles de bajas emisiones y crear la infraestructura
necesaria para su suministro.
El hidrógeno, como vector energético, jugará un papel central en los próximos 30
años. Este artículo examina los combustibles actuales, el impacto del hidrógeno y
las alternativas existentes en el sector marítimo, además de analizar el impacto de
la situación medioambiental en la demanda de nuevos buques, desde una perspec‐
tiva legislativa y económica.
Como conclusión, se destaca el Gas Natural Licuado (GNL) como un combustible
de transición hacia una tecnología basada en hidrógeno con el potencial de alcanzar
los objetivos de descarbonización para 2050. Sin embargo, hay retos importantes
que se deben abordar como el almacenamiento de hidrógeno, la falta de infraes‐
tructuras y el desarrollo normativo y tecnológico.
[Abstract] Decarbonisation of the maritime sector is key to reducing polluting emis‐ sions. This involves adapting ships by installing new equipment, developing lowemission fuels and creating the necessary infrastructure for their supply. Hydrogen, as an energy vector, will play a central role in the next 30 years. This paper discusses current fuels, the impact of hydrogen and existing alternatives in the maritime sector and analyses the impact of the environmental situation on the demand for new ships, from a legislative and economic perspective. In conclusion, Liquefied Natural Gas (LNG) is highlighted as a transition fuel towards a hydrogen technology with the potential to achieve decarbonisation targets by 2050. However, there are important challenges to be addressed such as hydrogen storage, lack of infrastructure and regulatory and technological development.
