The use of energy storage technologies has become one of the promising methods in the sense of its high reliability, economic feasibility, and low environmental impact. The deep reinforced concrete (RC) pile foundation with the compressed air energy storage (CAES) technology was proposed as an efficient solution to optimize a power distribution during peak and non-peak periods. The main characteristic of this technique is that the compressed energy obtained from solar panels or wind turbines can be kept inside the deep pile foundation. This paper presents the preliminary analytical investigation results on the maximum compressed air pressure from thermodynamic cycles and corresponding structural responses of a deep pile foundation under various combined loading scenarios. The study identifies the critical tensile stresses of the proposed pile system using finite element analysis, and some recommendations were made for the proper practical design of a deep energy storage pile foundation system.
