Chemical conversion is a key technology for hydrogen storage. Two basic options exist in this field: reversible storage using organic carrier materials (energy carrying compounds) and irreversible conversion into hydrocarbon fuels (gas‐to‐fuel). It has been shown that reversible storage exhibits significantly higher overall storage efficiency for the electricity‐to‐electricity storage process. The high storage density and existing infrastructure for hydrocarbon fuels are advantages of the Fischer‐Tropsch‐process whereas process complexity favors reversible conversion.
