Design of solar hydrogen refuelling station for hydrogen powered bicycles

Abstract

Nakon izrade prvog hrvatskog bicikla na vodik logičan slijed događaja bila je izgradnja prve hrvatske punionice vodika kako bi se pokrile potrebe bicikla. U ovom je radu predstavljen prijedlog izvedbene projektne dokumentacije samog kućišta punionice koji svojim jedinstvenim izgledom kemijsku formulu vodikove molekule.Ponuđen je i prijedlog povezivanja radnih komponenti sustava u funkcionalnu cjelinu s pozicijama u kućištu. Opisani su načini rada podsustava za proizvodnju električne energije preko fotonaponskih (FN) modula, te podsustava za proizvodnju vodika elektrolizom vode na samoj lokaciji. Punionica tako ispunjava zahtjeve za autonomnim radom. U radu je dan opis testiranja bicikla na vodik s pripadajućim rezultatima koji će se puniti na novoinstaliranoj punionici. Pomoću proračuna FN modula i podataka o potrošnji bicikla predstavljeni su podaci o potencijalu proizvodnje vodika u punionici.After making of the first Croatian hydrogen bicycle, a logical step was the construction of the first Croatian hydrogen refuelling station to meet the needs of the bicycle consumption. This work presents the proposal of the project design documentation of the hydrogen refueling station, with its unique appearance inspired by a molecular scripture of the hydrogen molecule itself. Paper also presents the functional scheme of system components to a functional unit with the positions suggestions of every part in the housing. The subsystem for the production of electricity through the photovoltaic modules and the subsystem for the production of hydrogen by electrolysis of water at the location were described. Hydrogen refueling station thus fulfills the requirements for autonomous work. Finally, there was description of the hydrogen bicycle testing with the corresponding results to be replenished in the newly installed hydrogen refuelling station. The calculation of photovoltaic module power production projections and bicycle consumption data were used to calculate full potential of hydrogen production in the HRS
