Nowadays the use of hydrogen as an energy carrier is rising a large interest, thanks to the development of the renewable energies. Indeed, hydrogen has been enlightened as one of the main actors of the incoming energetic transition, thanks to the possibility to produce it via water electrolysis fed by renewable energies, thus stocking the energy produced. The development of liquid hydrogen allows to resolve some of the main issues of the commonly used compressed gaseous hydrogen, such as its low energetic density and the high compression costs. Nevertheless, the liquefaction of the green hydrogen can have some major issues, when its production come from renewable energies having an intermittent nature, such as solar and wind energy.
