Modularized hydrogen energy ship electric transmission power system and method

Abstract

The invention discloses a modularized hydrogen energy ship electric transmission power system and method. The system is provided with a methanol reforming hydrogen production module, a fuel cell module, a power motor module and a low-pressure adsorption hydrogen storage module, the first feeding end of the fuel cell module is connected with the methanol reforming hydrogen production module, the second feeding end of the fuel cell module is connected with the low-pressure adsorption hydrogen storage module, and the feeding end of the low-pressure adsorption hydrogen storage module is connected with the methanol reforming hydrogen production module; and the output end of the fuel cell module is connected with the direct current transformation module, and the output end of the direct current transformation module is connected with the power motor module. Existing high-pressure hydrogen storage is generally 70 MPa, a fuel cell has potential safety hazards, and low-pressure adsorption storage is adopted in the method, so that the method is safe and reliable; and methanol water reforming hydrogen production heating needs about 10 minutes, when the ship is started, the low-pressure adsorption hydrogen storage module is used for providing hydrogen, meanwhile, the storage battery module provides supplementary electric power, and the requirement for high-power power in the initial starting stage of the ship is met.

Description

technical field [0001] The present invention relates to the technical field of ship power, in particular to a modular hydrogen-energy ship electric transmission power system and method. Background technique [0002] my country is a big ocean shipping country, a big inland shipping country, and a big ship manufacturing country. There are 172,600 ships registered in the country, with a displacement of 244 million tons, accounting for 1 / 10 of the world; there are 1,052 shipbuilding enterprises above designated size in the country. All shipping ships are fuel oils extracted from "energy-containing energy" petroleum products, and are powered by internal combustion engines. [0003] At present, the new energy lithium battery application technology for ships has just started, mainly represented by China Shipbuilding Industry Corporation, Chongqing University, Wuhan University of Technology and other units. There is still a long way to go in the future. The application of lithium b...
