Disclosed is a paired compress gas energy power system and power method. The paired compress gas energy power system includes: a paired compress gas energy storage device having a high pressure air container and a low pressure air container, the high pressure air container is filled with a high pressure gas, the low pressure air container is filled with a low pressure gas; a paired compress gas energy engine, respectively connected to the low pressure air container and the high pressure air container; and a power device connected to the rotary shaft of the paired compress gas energy engine, the power device is driven by the paired compress gas energy engine. The invention converts the paired compress gas energy into the mechanical torque energy through the paired compress gas energy engine to drive the power device to work, or to drive the generator to generate electric energy.
