Natural zeolites have been used in a wide variety of applications over the world. Among these, its utilization for carrying energy in energy conversation and heat exchanging systems is noteworthy. The main objective of the present study is to investigate potential and utilization opportunities of natural zeolites in energy-related applications. In this regard, the reserve potential of natural zeolites in Turkey is presented, while their worldwide application areas, current, and other utilization opportunities are given. High water adsorption capability and energy storage properties of natural zeolites are studied. The results of experimental studies conducted to determine the physical and chemical properties as well as the thermal conductivity values of the Gordes zeolite (Clinoptilolite type) with highly qualified, about one billion ton of mine deposit as energy storage material, are also presented.
