Abstract

A ship hydrogen hybrid power propulsion system and a method thereof are provided. The ship hydrogen hybrid power propulsion system includes a motor, a propeller, a power battery, an external motor controller, an internal motor controller, a hydrogen fuel cell, a hydrogen internal combustion engine, and a hydrogen storage tank. It combine the hydrogen fuel cell with the hydrogen internal combustion engine, and the hydrogen fuel cell is combined with the power battery and dynamically coupled with the internal motor and the external motor. Only a single hydrogen energy is needed, which is conducive to the layout and integration of the power system and achieves zero carbon emissions. Compared to the current dual motor power system, it has high integration, simpler power coupling, and a wider range of power output, making it particularly suitable for the high load and high-power output requirements of heavy-duty ships.
