From an environmental point of view, the use of hydrogen as a carbon-free energy source certainly has its advantages and will play a central role in future energy supply. In view of the globally rising energy demand and the limited availability of fossil ressources, as well as increasing environmental pollution caused by the emission of pollutants, it makes perfect sense to consider hydrogen as a possible alternative. Hydrogen can be produced virtually emission-free with the help of electrolysis and renewable energy sources such as hydropower, wind energy and solar power, and thus has the potential to be a major energy store. In addition to the challenge of producing hydrogen in an energy-efficient manner, the storage and distribution of hydrogen will play an important role. Hydrogen can be stored in many ways. Due to its low volumetric density under standard conditions, the handling of hydrogen differs from the previously used energy sources. The volumetric energy density of hydrogen at atmospheric pressure and room temperature is so low that it is in any cas necessary to increase this energy density by increasing the pressure, liquefying or by chemical or physical bonding to another substance. In this work, based on data known from the literature, various existing and potential storage technologies of hydrogen are presented and partly compared with each other depending on the field of application.
