Description

technical field [0001] The invention relates to the field of ship manufacturing, in particular to a hydrogen fuel ship capable of reducing NOx emissions. Background technique [0002] At present, more than 95% of ships mainly use internal combustion engines as power generation devices for ship power stations. The internal combustion engine burns the fuel and the oxygen in the air at high temperature to drive the power generation device to convert the fuel into electrical energy, and at the same time the nitrogen in the air reacts with the oxygen to form nitrogen oxides. [0003] If the internal combustion engine is used to drive the power generation device to generate electricity, it will inevitably produce a large amount of nitrogen oxide emissions, pollute the environment, and fail to meet the emission requirements of EU ports for nitrogen oxides. [0004] At present, hydrogen fuel cells for land use can meet the requirements of no nitrogen oxide emissions. Liquid hydroge...

Problems solved by technology

[0003] If the internal combustion engine is used to drive the power generation device to generate electricity, it will inevitably produce a large amount of nitrogen oxide emissions, pollute the environment, and fail to meet the emission requirements of EU ports for nitrogen oxides

[0004] At present, hydrogen fuel cells for land use can meet the requirements of no nitrogen oxide emissions. Liquid hydrogen fuel needs to be kept at an ultra-low temperature of -253°C at normal pressure or at an ultra-high pressure of 73Mpa at normal temperature. Its transportation and storage are difficult and costly; the energy density per unit volume of hydrogen fuel is low. , storage of hydrogen fuel on board needs to occupy a large amount of cargo space, reducing the profit margin of the ship

There is no better solution for the use of hydrogen fuel in ships
