In cooperation with OEMs and H2 initiatives, the topic of storage solutions for hydrogen has been intensively pursued at SAG for some time. Thus, various scenarios are being investigated for which the use of H2 could be interesting. The focus is on the development of efficient solutions for cryogenic storage of LH2. The use of liquid hydrogen as a fuel brings significant advantages. Among others: a higher range and payload, shorter refueling times, more transport volume.
Hydrogen is a chemical element, at standard conditions (20 °C and atmospheric pressure) it is a light gas (7 % air density). 1,000 liters have only 0.09 kg.
However, it can be compressed (350 or 700 bar) or liquefied (-253°C) to increase density.
