In the authors’ previous study, the feasibility of a reinforced concrete (RC) deep pile foundation system with the compressed air energy storage (CAES) technology was examined, from which the limitation of an RC deep energy pile foundation was clearly found in its serviceability performances. To overcome such a limitation, in this study, a concrete-filled tube (CFT) pile foundation system was introduced as a dual functional system for an energy storage media and structural deep foundation. Extensive finite element analyses were conducted to estimate the overall structural responses of the CFT energy pile system considering the combined effects of structural loading, soil conditions, and internal air pressures. The finding obtained from this study indicates that the CFT deep energy foundation can provide improved serviceability performances
