Overview on the potential role of hydrogen in the decarbonization of ports areas. The case of teh port of Valencia and the port of Trieste

Abstract

[ES] Analizar la demanda de calefacción, refrigeración y energía de los puertos de Valencia/Trieste, y realizar un análisis detallado de la demanda potencial de hidrógeno para los vehículos portuarios y la industria ubicada en la zona portuaria.

[EN] Decarbonization of ports is an important topic to address in order to ensure sustainability and environmental care. The use of fossil fuels associated with port operations and activities is a cause of air and water pollution. Decarbonization involves reducing harmful emissions in pursuit of an energy and ecological transition that combats climate change. To achieve this, it relies on renewable energy, electrification of vehicles and machinery, efficient infrastructure, and ecofriendly practices. The literature mentioned provides examples of actions and research being carried out within the port sector with the objective of making port operations as eco-friendly as possible. Given the complexity of this sector, improvement proposals have a wide range of applications, from mitigating emissions during ship berthing to optimizing container movements within the terminal. To conduct this study, various data from previous works on the operations of the ports of Valencia and Trieste have been analyzed with the aim of creating an adaptable improvement model for other ports. Through the study of these data, it has been concluded that there are various aspects that can be improved, which could lead to a satisfactory change in terms of emissions and costs. Once the ideas were formulated, the necessary calculations were performed to assess their viability. To achieve this, it has been necessary to formulate equations that yield useful results, research among possible options to choose those that will have the greatest impact and define conversion factors for energy generation and emissions of the proposed fuels. Through this process, we apply the literature to a practical case, namely the ports of Trieste and Valencia, to determine whether these measures are suitable for ports with different characteristics. The main results you will find include savings in terms of costs, emissions, and energy consumption that would result from implementing the measures explained in the study. Additionally, there is a brief analysis describing how the ports currently operate and highlighting areas in which improvements should be made. Finally, there is a comparation between the two ports under study.
