Abstract
Advantages of using hydrogen as a source of energy and silicate materials for its storage, in place of metal hydrides, have been explained. The silicates studied are vermiculites (from France, Spain and artificially prepared), montmorillonite, chlorite (USA) and zeolites (artificially prepared). It has been shown that finely divided metal particles (15–100 Å) can be formed in the interlayer space of clay minerals or in the structural voids of zeolite under suitable conditions and these can serve for storing hydrogen.
