Referring again to fig. 1, floating platform 100 includes an upper buoy 110, a lower buoy 120 coupled to upper buoy 110, and a deck 130 coupled to upper buoy 110. When floating platform 100 is floating on the sea, lower float 120 is located below the water surface, upper float 110 extends out of the water surface, power generation device 200 is connected to at least one of upper float 110 and lower float 120, and hydrogen generation device is connected to at least one of upper float 110 and lower float 120.

When the power generation device 200 is short of power supply, the hydrogen stored in the hydrogen storage container 300 can be delivered to the hydrogen fuel cell to enable the hydrogen fuel cell to generate electric energy, so as to supply power to the offshore floating hydrogen production and storage system 10 through the hydrogen fuel cell.
