Assessment of the potential for underground hydrogen storage
Estimates based on the developed methodology indicate that the average hydrogen storage potential for the analyzed salt domes ranges from 125.7 TWht after the first filling to 83.8 TWh t after 30 years of operation. The maximum storage potential ranges from 178 to 155 TWh t, respectively. In the case of the largest analyzed salt dome, where
Stability evaluation of the underground gas storage in rock salts based on new partitions of the surrounding rock | Environmental Earth Sciences
Due to the rheology, low permeability, and damage recovery of rock salts, the salt caverns have been widely used for natural gas and compressed air energy storage (Yang et al. 1999). The salt caverns have been used for gas storage for several decades in Europe and America (Bauer et al. 2013 ; Brown et al. 2014 ; Dethlefsen et al. 2014 ).
Numerical Assessment of the Geothermal and Thermal Energy Storage Potential of the Underground
Flooded mines constitute groundwater reservoirs that can be exploited with geothermal heat pump systems. Modelling such a reservoir is challenging because groundwater flow and heat transport equations need to be solved within the complex geometry of mine workings. To address this challenge, we developed a tridimensional
Tightness of an underground energy storage salt cavern with adverse geological conditions
Accurately determining the permeability of rock salt is a critical issue for the tightness assessments of salt caverns used for energy storage, which is also a hot topic in underground energy storage. Stormont [18] found that the permeability of the rock salt disturbed by cavern construction is about 10–10 5 times that of the non-disturbed areas.
Characterizing Hydrogen Storage Potential in U.S.
If all available working gas in UGS facilities (1,282 TWh) were used (Table 1), underground storage could buffer up to 16% of the U.S. natural gas demand. This excess energy storage could help ease

Highlights. •. The bulk of Ontario''s energy supply is provided by wind or nuclear energy. •. The prevalence of these energies result in periods of surplus energy supply. •. This surplus energy can be stored as hydrogen gas to buffer supply and demand. •. Underground storage in geological media is explored for Ontario.
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 ).

Large-scale oil storage needs good storage mediums, the world''s main ways of storing oil include storage tanks, underground rock caverns, and salt caverns [[4], [5], [6]]. The storage tank is built easily due to the metal structure, but it occupies lots of lands and is easy to leak, so the risk of the oil storage tank is high [ 7 ].
The role of underground salt caverns for large-scale energy storage
Large-scale energy storage is so-named to distinguish it from small-scale energy storage (e.g., batteries, capacitors, and small energy tanks). The advantages of large-scale energy storage are its capacity to accommodate many energy carriers, its high security over decades of service time, and its acceptable construction and economic
