Energy storage is one of the central issues of the energy transition due to the natural fluctuations of renewable energies. Solutions for long-term storage are particularly in demand - this is where hydrogen comes into play as a storage medium. Although it can be stored in a variety of ways, hydrogen is usually stored in gaseous form in high-pressure containers that are installed on site at the manufacturer's and user's premises as well as mounted on road and rail vehicles. Thus, hydrogen reaches the various users and H2 refueling stations mainly in a gaseous state.
In order to refuel more efficiently in the future, filling stations are needed that can refuel significantly more vehicles. Filling station concepts for liquid hydrogen storage are best suited for this. These have the advantage that liquid hydrogen (LH2) requires only one seventh of the volume of hydrogen gas (GH2), thus enabling significant space savings.
