Thermal energy storage is based on sensible and/or latent thermal energy storage methods [14]. With the sensible method, heat is released or stored by lowering or raising the thermal mass material''s temperature. Whereas with the latent method, heat is released or stored as a material''s phase change [15]. The amounts of sensible and

Simply put, energy storage is the ability to capture energy at one time for use at a later time. Storage devices can save energy in many forms (e.g., chemical, kinetic, or thermal) and convert them back to useful forms of energy like electricity. Although almost all current energy storage capacity is in the form of pumped hydro and the

Therefore, the role of the base isolation device isolating the superstructure from the ground motion does not perform properly, which causes amplification of the floor response of the superstructure. In practice, the second hardening of the isolator material might need to be taken into account for designing the base isolation system.
