The present disclosure relates to a natural gas hydrate tank container loading system for transporting natural gas hydrate, and the present disclosure provides a natural gas hydrate tank container loading system, enabling self-powered power generation and boil-off (BOG) gas treatment, includes: a refrigerator for inhibiting the generation of boil-off gas which naturally generates in a natural gas hydrate tank container during transportation; and a solar cell, a battery, and a generator, which operates by means of the boil-off gas, for supplying electric power to the refrigerator, thereby ensuring a generation capacity sufficient to operate the refrigerator by means of the solar cell, the generator, and the battery, and thus always maintaining a stable phase equilibrium (self-preservation) in the natural gas hydrate tank container even during long-distance transportation and solving problems of fire, environmental pollution, or the like which occur when the boil-off gas (BOG) is discharged to the outside.

A system for storing air at high pressure underground or underwater includes a plurality of arrays of air tanks, each tank configured to store compressed air at a pressure of at least 40 bar. A piping system connects between an outlet of each air tank, the piping system further including at least one central port for delivering compressed air to and from a respective array. A storage receptacle surrounds the arrays and piping system, protecting the arrays and piping system from an external environment, and thermally insulating the arrays and piping system. A liquid bath is arranged within the storage receptacle. A heat exchanger is configured to maintain a temperature of the liquid bath substantially constant. The storage receptacle may be comprised of plastic pieces welded together in a modular fashion. Each piece may be a cylindrical tube configured to receive therein one or more of the arrays.
