For a gravity hydraulic energy storage system, the energy storage density is low and can be improved using CAES technology . As shown in Fig. 25, Berrada et al. introduced CAES equipment into a gravity hydraulic energy storage system and proposed a GCAHPTS system.
(2) Energy storage state. In the energy storage state, the hydraulic pump rotates to pump water to rotate the hydraulic motor. When the absorbed power exceeds the grid demand, the excess rotating mechanical energy is used to drive the compressor for air compression.
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. These storage options are not only essential for developing multiple renewable energy sources, but also for ensuring continuity of supply and increasing energy autonomy.
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 The regulatory context is crucial to understanding the value of storage.
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.
