  • the refueling stations intended for the distribution of fuels for vehicles need to supply regularly and to store fuels in temporary storage tanks, from which they are taken to supply the customer vehicles.
  • Hydrogen is a highly environmentally friendly solution because, in systems of the Fuel Cell type, in the presence of oxygen there is the production of electricity and the only formation of hot water as waste.
  • the main ways to store hydrogen on a vehicle are:
  • the latest generation cylinders are designed to withstand a nominal pressure of 700 bar and are suitable for small vehicles such as scooters and cars;
  • liquid hydrogen the container is a large thermos, more suitable for large vehicles (trucks, buses).
  • liquid hydrogen delivered by tanker to a refueling station is sold or used within few days, in order to avoid wastefulness.
  • Some refueling stations are instead provided with a hydrogen generator that exploits the electrolysis of water, which is an electrolytic process in which the passage of electricity causes the decomposition of water into oxygen and hydrogen.
  • the main aim of the present invention is to devise a hydrogen refueling station that allows obtaining a supply of hydrogen in a practical, easy and functional way, while significantly reducing the quantity of hydrogen that you need to transport and store.
