Abstract

The invention discloses an efficient hydrogen storage device. The efficient hydrogen storage device comprises an inner container as well as an outer container and a cold insulation layer which are sequentially coated, wherein the inner container is filled with a filler, and the filler is formed by sintering a composite material of graphene and magnesium and is cylindrical; the inner container is made of an aluminum alloy material; and the composite material of graphene and magnesium is stretched into a filiform structure or a sheet structure, and then prepared into the filler. The novel hydrogen storage device has the advantages of mild operation temperature, low hydrogen storage pressure and the like, a hydrogen storage process is simple and high in automation degree, the adopted equipment is reliable, the preparation cost and liquefaction cost of hydrogen are increased, and remarkable economic benefits are achieved.

Description

technical field [0001] The invention relates to a high-efficiency hydrogen storage device, which belongs to the technical field of hydrogen energy utilization. Background technique [0002] Hydrogen energy is recognized as a clean energy source. Due to its advantages of high energy density and zero carbon emissions, it is considered to be the most potential substitute for fossil fuels in the future. The ultimate solution”, green hydrogen can also be used as a source of hydrogen in the hydrogenation process of fossil resources to achieve carbon emission reduction. As a new secondary energy source, hydrogen energy will play an important role in low-carbon emission reduction and future green energy system. The International Hydrogen Council predicts that hydrogen will account for 18% of energy consumption in 2050. By 2050, the proportion of hydrogen energy in my country's energy structure is expected to reach more than 10%. [0003] The hydrogen energy industry chain is long...
