The hydrogen energy transportation device comprises a transportation pipeline (1), a hydrogen energy mixing device (2) arranged at the input end of the transportation pipeline (1), and a hydrogen energy separation device (3) arranged at the output end of the transportation pipeline (1), wherein the hydrogen energy mixing device (2) comprises a mixing pipeline (21), a hydrogen energy pipeline (22) and other one energy pipeline (23); the mixing pipeline (21) comprises two input ends and one output end; the two input ends of the mixing pipeline (21) separately communicate with the hydrogen energy pipeline (22) and the other one energy pipeline (23); and the output end of the mixing pipeline (21) communicates with the input end of the transportation pipeline (1). According to the hydrogen energy transportation device and the hydrogen energy transportation method, natural gas and hydrogen are mixed through a conventional natural gas transportation pipeline, mixed natural gas and hydrogen are sent into the transportation pipeline (1), and hydrogen is transported; and relative to a transportation method in the prior art, the transportation method has the advantages that hydrogen transportation efficiency is greatly improved, and transportation cost is reduced.

Description

technical field [0001] The invention relates to the technical field of hydrogen transportation and pipeline transportation, in particular to a hydrogen energy transportation device and transportation method. Background technique [0002] Hydrogen is a highly volatile and high-energy energy carrier, fuel and petrochemical raw material. Hydrogen can not only be used in industrial production to produce synthetic ammonia, methanol and hydrogenation reactions in petroleum refining processes, but can also be used in large quantities in Electronics industry, metallurgical industry, food industry, float glass, fine organic synthesis, aerospace and other fields, and because hydrogen fuel has the advantages of no pollution, high efficiency, and recyclability, hydrogen fuel is considered to be the most important fuel in the 21st century. Ideal energy. [0003] Although hydrogen has a high application value and a wide range of applications, since hydrogen is a flammable and explosive g...

AI Technical Summary

Problems solved by technology

[0003] Although hydrogen has a high application value and a wide range of applications, since hydrogen is a flammable and explosive gas, it can explode within a wide explosion limit range of 4%-74.2%, so even a small amount of air mixed in may cause explode

Therefore, there are great potential safety hazards in the storage, transportation and application of hydrogen.

[0004] From the perspective of transportation, whether it is the low-temperature transportation of liquid hydrogen or the transportation of high-pressure tanks, this ultra-low temperature and high-pressure process will cause energy consumption on the one hand, and higher transportation costs on the other hand.

[0005] From the application point of view, large-scale fuel cell power generation technology and hydrogen gas turbine power generation technology are also affected by hydrogen transportation and the lack of cheap and stable hydrogen sources, and the current development is slow
