PROBLEM TO BE SOLVED: To provide a high pressure gas accumulation system capable of reducing a load of a high pressure stage compressor immediately after start of pressure accumulation.SOLUTION: A high pressure gas accumulation system 1 includes: a gas supply source 2; an accumulator 3; a supply gas line L1; a low pressure-stage compressor 4 disposed in the supply gas line L1; a high pressure-stage compressor 5 disposed at a secondary side of the low pressure-stage compressor 4; a first driving gas line L2 for supplying a first driving gas to the low pressure-stage compressor 4; a second driving gas line L3 supplying a second driving gas to the high pressure stage compressor 5; a bypass line L4 disposed to communicate the first driving gas line L2 with the second driving gas line L3; a first opening/closing valve 7 disposed in the second driving gas line L3; and a second opening/closing valve 8 disposed in the bypass line L4. A supply pressure of the second driving gas is lower than a supply pressure of the first driving gas.SELECTED DRAWING: Figure 1 |
