Hydrogen energy supply chain

Abstract

A hydrogen energy supply chain comprises a liquefaction factory, a low-temperature storage tank, a pump, a vaporizer, gas cylinders and hydrogen adding mechanisms. The technological process of the hydrogen energy supply chain has the technical characteristics that hydrogen gas produced through hydrogen production by a hydrogen resource place is liquefied into liquid hydrogen by the liquefaction hydrogen factory, then the liquid hydrogen is conveyed to a hydrogen user market place through a low-temperature storage tank transport means, is pressurized through the pump and is vaporized into high-pressure gaseous hydrogen through the vaporizer, the gaseous hydrogen is loaded to the gas cylinders, and then the gas storage cylinders of hydrogen fuel cells are filled completely to the rated pressure through hydrogen adding machines. According to the hydrogen energy supply chain, hydrogen liquefaction, storage, transport and other proven technologies in the aerospace field of China are used and extended to the downstream, pressurization of the pump and vaporization of the vaporizer are added for obtaining the high-pressure hydrogen gas, and the complete hydrogen energy supply chain is formed with combination of personal authorized patent technology of a gas station.

Description

Technical field [0001] The invention relates to a hydrogen supply chain equipment and method, which is a continuous whole process from produced hydrogen to hydrogen energy users, belonging to the field of hydrogen energy. Background technique [0002] Hydrogen is a secondary energy source with high combustion calorific value and zero CO2 emission. The heat produced per kilogram of hydrogen is about 3 times that of gasoline, 3.9 times that of alcohol, and 4.5 times that of coke. [0003] Since hydrogen is the only energy that can provide neither the "greenhouse effect" nor any pollution, it is inexhaustible and inexhaustible. People have gradually realized that hydrogen energy technology will be the most promising and most fundamental in the 21st century. As the ultimate means to solve the human environmental crisis and energy crisis, the corresponding hydrogen fuel cell vehicle is the ultimate version of humanity. The only way to connect hydrogen energy and hydrogen fuel cell vehic...

Problems solved by technology

[0021] Shanghai Anting Hydrogen Refueling Station is an external hydrogen refueling station. The hydrogen transported needs to be repressurized at the hydrogen refueling station. The compression equipment and the gas storage cylinder group in the station occupy a large area, and the operating cost is high, which is obviously economical. Not the best, it was later changed to a joint construction of a charging station and a hydrogen refueling station, obviously from an economic point of view

[0022] 3. The current hydrogen refueling station technology is expensive to build and it is difficult to replicate on a large scale:

[0026] Furthermore, the hydrogen purity required by the hydrogen refueling station must be above 99.99%, and the pressure must be above 70MPa. The gas compressor requirements for each station are very high, and the number of corresponding air refueling guns is limited by the outlet displacement of the compressor. , the number of refueling gun
