Design of a Hydrogen Refueling Station with hydrogen production by electrolysis, storage and dispensing for a bus fleet in the city of Valencia

Hydrogen technologies are evolving to decarbonise the transport sector. The present work focuses on the technical design of a Hydrogen Refueling Station to supply hydrogen to five buses in the city of Valencia, Spain. The study deals with the technical selection of the components, from production to consumption, setting an efficient standardisation method. Different calculation are used to size the storage systems for 70.8 kg of hydrogen produced by the elecrolyser daily. For the high-pressure storage system, massive and cascade methods are proposed, being the last one more efficient (1577.53 Nm3 non usable volume compared to 9948.95 Nm3 of the massive method).
