Abstract
A hydrogen gas supply method and the hydrogen gas supply system is provided, including a low-pressure compressor 1 and a high-pressure compressor 2 that compress hydrogen gas, in which a necessary pressure at a supply destination includes a low-pressure region and a high-pressure region and the hydrogen gas is supplied to the supply destination in accordance with the necessary pressure. The low-pressure compressor 1 is a piston crank type compressor. The high-pressure compressor 2 is a hydraulic compressor or a diaphragm type compressor. When the necessary pressure at the supply destination is in the low-pressure region, the hydrogen gas compressed by the low-pressure compressor 1 is supplied to the supply destination.
