ScienCity es una actividad que viene siendo continuada desde 2018 con el objetivo de dar a conocer los conocimientos y tecnologías emergentes siendo investigados en las universidades, informar de experiencias, servicios e iniciativas puestas ya en marcha por instituciones y empresas, llegar hasta decisores políticos que podrían crear sinergias, inc...

Water‐based hydrogen production is currently an attractive research field, as it provides a greener method to produce hydrogen than existing alternatives. Green hydrogen is expected to progressively replace fossil fuels, which are highly harmful environmentally. This paper presents a critical analysis over time of the main water splitting technolog...

The increasing use of renewable sources requires systems able to manage supply, store energy and meet demand, both locally and distributed to the main grid. The generation management, as well as storage and supply of energy to end users, requires adequate strategies and control systems, frequently based on simulations. This work proposes a methodol...

Green hydrogen has been postulated as an alternative of great interest in the sustainable storage of energy [1], [2]. Its production by electrolysis does not produce pollutants. In addition, if the electricity necessary for its production comes from renewable sources, [3]-[5]. Electrolysis technology is increasingly reaching milestones in its devel...

This paper presents a comprehensive experimental analysis about the influence of supercapacitor banks as energy storage system (ESS) in renewable energy sources-based (RES-based) microgrids with high voltage DC bus. The analysis includes a comparison between the microgrid performance supported by conventional ESS such as batteries (lead-acid and li...

This paper presents the design, modelling and control simulation of the Balance of Plant (BoP) for a medium- size PEM (Proton Exchange Membrane) electrolyzer. Taking into consideration the main chemical process that occurs in the electrolysis of a PEM electrolyzer, the BoP must be clearly divided into two main parts: water management and hydrogen p...

The percentage of the population in urban areas has increased by ten points from 2000 (46%) to 2020 (56%); it is expected to reach up to 70% by 2050. This undoubtedly will encourage society to use alternative transports. On the other hand, the widespread fear of pandemics seems to be here to stay, and it is causing most people to leave public trans...

Energy management linked to building technology is a key factor within the objectives of the European Green Deal, as well as the Sustainable Development Goals. Towards climate neutrality, and the flexible and sustainable management of energy demand, many residential developments have installed photovoltaic systems in recent years, as well as batter...

Actualmente, nuestras ciudades están experimentando una verdadera transformación digital que requiere una atención inmediata en energía, transporte, movilidad, comunicación, seguridad, educación, turismo y aspectos sociales, así como fomentar todas aquellas actuaciones que persigan mejorar la calidad de vida y el desarrollo económico-ambiental sost...

The rise of hybrid electric vehicles on the roads is a reality. The European Green Deal reflects this trend and proposes a series of measures to achieve the necessary decarbonisation of Europe. A large increase in these vehicles is expected, so it is necessary to increase the refueling stations, as well as improve their operation. So, in addition t...

This paper presents a prominent e-learning tool that is part of the Hy2Green Project (Ref. 2017-1-ES01-KA203-038302). According to the European energy transition, this project offers an online training program aimed to the new professionals that will be needed. To undertake such challenge, the training module is completed with the development of a...

The main novelty lies in developing a general control-oriented model that, taking into accou...

The progressive increase in hydrogen technologies' role in transport, mobility, electrical microgrids, and even in residential applications, as well as in other sectors is expected. However, to achieve it, it is necessary to focus efforts on improving features of hydrogen-based systems, such as efficiency, start-up time, lifespan, and operating pow...
