New energy hybrid power ship development and trend analysis

In order to respond to the national "double carbon" goal and implementation, the introduction of new energy (solar energy, wind energy, etc.) in the ship power system is one of the main methods to reduce environmental pollution and energy shortage in shipbuilding industry, but only relying on solar energy or wind energy cannot meet the whole ship load demand power, so we must increase the energy storage system to ensure the ship Reliability of power supply. The ship hybrid power system has good handling performance, high power conversion efficiency, low emission cost consumption and other characteristics and become one of the main development directions of the future shipbuilding industry. This paper firstly puts forward the necessity of the development of new energy hybrid ship and introduces the application of traditional ship power system and new energy on the ship; then introduces the hybrid power technology of solar and lithium battery hybrid ship; finally, the future development of new energy hybrid ship is prospected.
