Hydrogen compression system

A hydrogen compression system comprising:

• a heat pump part comprising a heat pump line configured to allow a refrigerant to circulate therethrough;
• a hydrogen compression part configured to compress hydrogen by being repeatedly heated and cooled;
• a first circulation line connected to the heat pump line while passing through the hydrogen compression part and configured to allow the refrigerant introduced from the heat pump line to circulate therethrough;
• a second circulation line provided to pass through the hydrogen compression part and configured to allow a cooling fluid to circulate therethrough;
• and
• a cooling unit provided in the second circulation line and configured to cool the cooling fluid,
• wherein the hydrogen compression part is heated by the refrigerant or cooled by the cooling fluid,
• wherein the hydrogen compression part comprises:
• a first compression part configured to compress the hydrogen;
• and
• a second compression part configured to compress hydrogen independently of the first compression part, and
• wherein the first and second compression parts are alternately heated or cooled,
• wherein the hydrogen compression system further comprises:
• a first bypass line having a first end disposed at an upstream side of the first compression part and connected to the first circulation line, and a second end disposed at an upstream side of the second compression part and connected to the second circulation line;
• a second bypass line having a first end disposed at a downstream side of the second compression part and connected to the second circulation line, and a second end disposed at a downstream side of the first compression part and connected to the first circulation line;
• a third bypass line having a first end disposed at the upstream side of the second compression part and connected to the second circulation line, and a second end disposed at the upstream side of the first compression part and connected to the first circulation line;
• and
• a fourth bypass line having a first end disposed at the downstream side of the first compression part and connected to the first circulation line, and a second end disposed at the downstream side of the second compression part and connected to the second circulation line.
