1. A hydrogen storage system comprising:
a storage container configured to store liquid hydrogen;
a supply line having a first end portion connected to the storage container and a second end portion connected to a fuel cell system, the supply line being configured to supply gaseous hydrogen to the fuel cell system from the storage container;
a compressor mounted in the supply line and configured to compress the gaseous hydrogen;
a bypass line connecting the supply line and the storage container and configured to allow the gaseous hydrogen to flow from the supply line to the storage container;
a control valve mounted in the bypass line and configured to selectively adjust a bypass flow rate of the gaseous hydrogen;
an orifice provided in the bypass line and positioned at a downstream side of the control valve; and
a controller electrically connected to the control valve and the compressor and configured to control the control valve and the compressor.
