Abstract: A hydrogen station operation method capable of adjusting pressure in a reservoir to the pressure suitable for liquid hydrogen replenishment while cutting hydrogen waste is for replenishing liquid hydrogen into the reservoir in a hydrogen station including: a gasification path partially gasifying liquid hydrogen out of the reservoir and returning it; and a gas delivery path delivering gasified hydrogen in the reservoir into a path between a vaporizer and a compressor or the vaporizer, when the remainder of liquid hydrogen in the reservoir becomes a first threshold or less, by reducing the liquid hydrogen amount flowing through the gasification path by a valve therein, reducing the gasification amount of liquid hydrogen in the reservoir, and increasing the hydrogen gas amount delivered through the gas delivery path from the reservoir by a valve therein, pressure in the reservoir is reduced, thereby performing operation where suction pressure of the compressor is reduced.

Abstract: The present application includes a compressor having a cylinder forming a compression chamber in which gas is compressed, a housing having a peripheral wall forming an internal space in which the compressor is stored, and a supporting member situated above the compressor in the internal space. The peripheral wall includes an opening wall in which a carry-out port is formed through which the cylinder is carried out. The supporting member extends to guide movement of a first lifting device between a position above the compressor and a position above the carry-out port. The cylinder is hung from the first lifting device.

Abstract: A gas supply device includes a first compressor that compresses hydrogen gas, an accumulator disposed downstream of the first compressor and supplying the hydrogen gas to a dispenser that fills the hydrogen gas in a vehicle, and a gas flow passage that connects the first compressor, the accumulator, and the dispenser, and a control device. The gas flow passage includes a lead-in line for leading the hydrogen gas into the accumulator, a lead-out line for leading out the hydrogen gas from the accumulator, a lead-in side valve, and a lead-out side valve. The control device is capable of simultaneously bringing the lead-in side valve and the lead-out side valve into an open state.
