Energy storage is one of the central issues of energy system transformation due to the natural fluctuations of renewable energies. Solutions for long-term storage are particularly in demand. This is where hydrogen as a storage medium comes into play. Although it can be stored in a variety of ways, hydrogen is usually kept in gaseous form in high-pressure containers, which are installed on site of the manufacturer or user's premises as well as on road and rail vehicles. In this way, the hydrogen mainly reaches the various consumers and H2 filling stations in a gaseous state.
In order to refuel more efficiently, filling stations will be needed in the future that can refuel considerably more vehicles at the same time than before. For this purpose, filling station concepts for liquid hydrogen storage are best suited. These have the advantage that liquid hydrogen (LH2) requires only one seventh of the volume of hydrogen gas (GH2), thus allowing significant space savings.
