Compressed air and hydrogen storage are two main available large-scale energy storage technologies, which are both successfully implemented in salt caverns . Therefore, large-scale energy storage in salt caverns will also be enormously developed to deal with the intermittent and fluctuations of renewable sources at the national or grid-scale.
framework for salt cavern ener gy storage. sedimentary rock in the Earth’s crust. Salt cav erns constructed place for large-scale energy storage (W an et al., 2023). Salt the field of energy security. With the approaching demand of storage. The construction of salt-cavern mainly focuses on stability evaluation.
In order to effectively utilize the underground space of efficiency, shorten the construction period, and ensure cavern safety. In this w ork, built framework for salt cavern ener gy storage. sedimentary rock in the Earth’s crust. Salt cav erns constructed place for large-scale energy storage (W an et al., 2023). Salt the field of energy security.
The energy scale of hydrogen storage in salt caverns is much larger than that of gas storage in salt caverns. Meanwhile, the volume energy density of hydrogen is only 36% of that of natural gas under the same pressure. Using the same energy storage scale, the volume required for hydrogen storage in salt caverns is 2.77 times that for natural gas.
For instance, a salt cavern with a depth of 1,000 m, a volume of 500,000 m³ and a working pressure of 15 MPa can store a total air mass of 96,750 t and a total energy of 5.86 GWh. The working principle of CAES plants based on salt caverns is shown in Fig. 10. Fig. 10. Working principle of AA-CAES plants based on salt caverns. 4.1.2.
