Various methods are available for the storage of hydrogen (H₂). Compressed storage and cryogenic liquid storage of hydrogen are the most commonly used in industry. Compressed hydrogen storage can take place in steel containers or containers made of a composite material. They are used, for example, for truck transport, vehicles and hydrogen storage in industry or at hydrogen filling stations. The pressure level here is between 20 and 90 bar. To store hydrogen in vehicles, the automotive industry relies on the use of pressure tanks, where the pressure level is up to 70 bar. This means that fuel cell vehicles have a similar range to petrol cars. In addition, it is generally possible to store hydrogen under extremely low overpressure (0.0022 bar) in gasometers.
