[EN] Nowadays, there is an increasing concern about how different energy systems impact on the environment and affect society. Accordingly, the search for alternative solutions to achieve a clean and sustainable energy system is becoming imperative. Specifically, for the transport sector, many technologies are being developed aiming at decarbonising the industry, and hydrogen is among them. The present work focuses on the technical design of a hydrogen refuelling station (HRS) located at the Polytechnic University of Valencia (UPV). The study deals with the selection of the components that form the hydrogen chain, from its production by Proton Exchange Membrane (PEM) electrolysis, through storage and compression stages, to the point of consumption where hydrogen is supplied to different fuel cell electric vehicles (FCEV). Through the use of this facility, greenhouse effect emissions are expected to be reduced, since the use of hydrogen as a fuel produces water vapor as its main emission by-product. TFGM
