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, and belongs to the field of hydrogen energy. Background technique [0002] Hydrogen is a secondary energy source with high combustion calorific value and zero CO2 emissions. The heat generated by the combustion of each 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 a "greenhouse effect" nor any pollution, it is inexhaustible and inexhaustible. People gradually realize that hydrogen energy technology will be the most promising and fundamental energy technology in the 21st century. The ultimate means to solve the human environmental crisis and energy crisis. The corresponding hydrogen fuel cell vehicle is the ultimate version of human car. The only channel to connect hydr...

AI Technical Summary

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 guns has not increased much, but the equipment manufacturing cost or investment has increased geometrically, resulting in high construction costs for hydrogen refueling stations, making it difficult to promote them on a large scale;

[0027] Secondly, it is necessary to consider the source of hydrogen and the production cost of hydrogen production. The price of hydrogen sales is related to the benefits of hydrogen refueling stations. At present, the hydrogen production equipment in stations for hydrogen production and supply hydrogen refueling stations has high investment and low gas production. The depreciation of equipment is very high, which affects the sales price. Due to the different resources in different places, that is, the source of hydrogen is different, it is difficult to unify the station construction mode of hydrogen production and supply hydrogen refueling stations in the station, and it is difficult to replicate and promote without a unified model;
