Underground Thermal Energy Storage

Underground thermal energy storage (UTES) is a form of STES useful for long-term purposes owing to its high storage capacity and low cost (IEA I. E. A., 2018).UTES effectively stores the thermal energy of hot and cold seasons, solar energy, or waste heat of industrial processes for a relatively long time and seasonally (Lee, 2012) cause of high thermal inertia, the

Numerical simulation on cavern support of compressed air energy storage

The working principle of compressed air energy storage is: during is used as the support structure and PE-RT is used as the sealing layer structure. In Korea [25], developed a pilot cave for CAES in hard rock (limestone) to monitor long-term energy storage operating data. Based on their field test data, gas temperature in CAES caverns can

Evaluation Methods of Salt Pillar Stability of Salt Cavern Energy Storage

Underground energy storage is essential for the country''s development, and underground salt cavern groups are a productive way to store energy. Safety pillar design is the key to ensuring the safe operation of large salt cavern gas storage groups. Therefore, this paper is based on the salt pillar stability design problem and analyzes three aspects: (1) Three kinds

Compressed air energy storage (CAES) is a promising energy storage technology, mainly proposed for large-scale applications, that uses compressed air as an energy vector. Although

Journal of Energy Storage

The basic principle of hydrogen storage is to produce hydrogen by electrolyzing water from excess renewable energy sources, compressing the hydrogen produced into a storage system to keep it for days to months, and use it as a clean fuel to power batteries or burn it directly during times of high demand [17, 18]. In recent years, major
