In this paper, three thermodynamic electricity storage technologies, namely CAES, CCES and PTES, are comprehensively reviewed. For each technology, the basic principle is firstly clarified and then system structures and storage devices are summarized. Thereafter, the corresponding demonstrations and costs of different routes are sorted out.

To store the energy, the system uses an injection/production well that extended from the ground surface to a deep aquifer. During the charging process, CO 2 is injected into the target deep aquifer through wellbore. During the discharging process, CO 2 is produced to the ground surface to complete the power generation process.
