Abstract
Disclosed is a system for storing high-pressure gas on the seabed. A gas compressor is used for continuously compressing gas into a sealed gas tank arranged on the seabed through a gas inlet pipe, so that the storage of the high-pressure gas is achieved. When the high-pressure gas in the sealed gas tank is needed for use, the sealed gas tank releases the high-pressure gas outwards through an exhaust pipe for energy conversion. The differential between inside pressure and outside pressure borne by a shell of the sealed gas tank is within the pressure range capable of being borne by the shell of the sealed gas tank when the sealed gas tank stores or exhausts the high-pressure gas. The system for storing the high-pressure gas on the seabed can effectively reduce the resultant force borne by the sealed gas tank, namely more high-pressure gas can be injected into the sealed gas tank, a thicker tank wall is not needed for supporting, and therefore the manufacturing cost of the sealed gas tank is lower. In addition, the sealed gas tank placed on the seabed is safer.
