HYDROGEN SUPPLY SYSTEM AND HYDROGEN SUPPLY/DEMAND MANAGEMENT METHOD

A hydrogen station 10 includes a water electrolysis device 12 that produces hydrogen gas by an electrolytic reaction consuming power supplied from a commercial power network 90, a compressor 14 that compresses the hydrogen gas produced by the water electrolysis device 12, an accumulator 16 that accumulates the hydrogen gas compressed by the compressor 14, a dispenser 18 that fills a fuel cell vehicle 92 with the hydrogen gas accumulated in the accumulator 16, and a control device 20 that controls a power consumption amount of the water electrolysis device 12 on the basis of a command for adjusting supply and demand of power of the commercial power network 90.
