Hydrogen-powered power generation device and method for driving power system on ship

Abstract

The invention discloses a hydrogen-powered power generation device and method for driving a power system on a ship and provides a hydrogen-powder device ship taking tidal current energy to electrolyzeand desalinate seawater to produce hydrogen. The device comprises a tidal current energy power generation system, an electrolysis hydrogen production subsystem and a hydrogen power generator, a freshwater outlet of a seawater desalination system is connected to a water inlet of the electrolysis hydrogen production subsystem, a hydrogen outlet of the electrolysis hydrogen production subsystem is connected with the hydrogen power generator, and an electric energy output end of the hydrogen power generator is connected with a power system which drives the ship to travel; the tidal current energypower generation system provides a power source to the electrolysis hydrogen production subsystem. The device can obtain raw materials (desalinated seawater) continuously and can perform electrolysisat any time to generate hydrogen to meet requirements on continuous traveling of the ship, and traveling mileage is increased. A parking for refueling link is omitted, so that time is saved, and an emergency that traveling cannot be realized without power fuel is avoided; the device is simple in principle and can be used in an unlimited manner for a long time, and repeated purchasing of diesel oil or coal-fired power raw materials is not needed, so that cost is saved.

Description

technical field [0001] The invention belongs to the application field of hydrogen production by electrolysis, and in particular relates to a hydrogen power generation device and method for driving a power system on a ship hull. Background technique [0002] China is one of the first countries in the world to manufacture canoes, and it has taken an important step in the history of ship technology development. Then, in the practice of long-term sailing, people created a ship that uses the wind to drive—a sailboat. As long as the sail and the wind direction are at a certain angle, the sail can be pushed forward by the wind that pushes the boat forward. After thousands of years of development, with the invention of the steam engine and the advancement of science and technology, the sail was finally replaced by machinery, and the sailboat gradually developed into a ship equipped with an engine. The steam engine was the first to replace the sail. The first steamboats were propell...
