Abstract An overview of the importance of and methods available for heat storage in the form of sensible and latent heat is followed by a discussion of the advantages and disadvantages of reversible thermochemical energy storage compared to conventional energy sources such as fuels, i.e. irreversible chemical energy carriers. Of the reversible metal‐hydride–metal systems, the MgH2Mg system is particularly attractive as a hydrogen and a high‐temperature heat storage material because of its high hydrogen content and the high energy content of the Mg–H bond. The advances made in this area over the past few years, namely in catalytic hydrogenation and the doping of magnesium powders, have led to the development of “active MgH2Mg systems” for energy storage. The first experimental results on high‐temperature heat storage (also with cooling) by coupling a MgH2Mg storage system with a low‐temperature metal hydride storage system are presented.
