Claim 0:
1. An energy storage system comprising:
a first container forming a first space to store an initial gas;
a second container connected to one side of the first container and having a second space to store an initial liquid;
when in a first operation mode of the energy storage system, a working fluid is injected into the second space, so that the working fluid drives the initial liquid to flow toward the first space, and further continuously compresses the initial gas in the first space until the initial gas in the first space reaches a predetermined pressure, thereby enabling the first container to store a first pressure energy;
when in a second operation mode, the initial gas continuously expands to drive the initial liquid to discharge, so as to convert the first pressure energy to a second pressure energy for driving a converter to generate electricity;
a first tube providing a first end and a third end, wherein the first end is coupled to the first container and the third end is coupled to the second container.
