Compressed Air Energy Storage(CAES)is one of the methods that can solve the problems with intermittency and unpredictability of renewable energy sources.A side effect of air compression is a fact that a large amount of heat is generated which is usually *** the development of CAES systems,the main challenge,apart from finding suitable places for storing compressed air,is to store this heat of compression process so that it can be used for heating the air directed to the expander at the discharging *** paper presents the concept of a hybrid compressed air and thermal energy storage(HCATES)system,which may be a beneficial solution in the context of the two mentioned *** novel concept assumes placing the thermal energy storage(TES)system based on the use of solid storage material in the volume of the post-mining shaft forms a sealed air pressure *** of proposed systems within heavily industrialized agglomerations is a potential pathway for the revitalization of post-mine *** potential of energy capacity of such systems for the Upper Silesian region could exceed the value of 10 *** the paper,the main construction challenges related to this concept are *** issues related to the possibility of storing air under high pressure in the shaft from the view of the rock mass strength are *** overall concept of the TES system installation solution in the shaft barrel is *** basic problems related to heat storage in the cylindrical TES system with a non-standard structure of high slenderness are also *** numerical calculations were based on the results of experiments performed on a laboratory stand,the geometry of which is to reflect the construction of a TES tank in a post-mining *** article presents the results of numerical analysis showing the basic aspects related to difficulties that may occur at the construction stage and during the operation of the proposed HCATES *** paper
