Hydraulic storage is significant because it fulfills a variety of roles in reinforcing renewable energy sources (RES) for services with different timeframes of operability: instantaneous, daily, or seasonally.

Context of hydraulic storage problems Two important developments in the energy sector should be considered in the interest of hydraulic storage: on the one hand, the regulatory context and, on the other hand, the context of energy decarbonisation. 1.1. The regulatory context
Hence, hydraulic compressed air energy storage technology has been proposed, which combines the advantages of pumped storage and compressed air energy storage technologies. This technology offers promising applications and thus has garnered considerable attention in the energy storage field.
The energy in the system is stored in (E) hydraulically or pneumatically and extracted from (E) when necessary. Since hydraulic pumps/motors tend to have a higher power density than pneumatic compressors/expanders, the hydraulic path is usually used for high-power transient events, such as gusts or a sudden power demand.
Perry Y. Li et al. first designed a new high-efficiency compressed air energy storage system for hydraulic wind turbines, as shown in Fig. 14. The principle is that the hydraulic power created by the pump in the nacelle drives the hydraulic transformer.
