Abstract

The invention discloses a high-pressure composite metal hydride hydrogen storage tank and a hydrogen storage method thereof. The hydrogen storage tank comprises a base support and a hydrogen storage tank shell with an opening in the bottom, and the hydrogen storage tank shell is installed on the base support in a sealed and buckled mode. A hydrogen inlet and a hydrogen outlet are formed in the hydrogen storage tank shell. A hydrogen storage alloy storage space, a gaseous hydrogen storage gap and a circulating heat exchange system are arranged in the hydrogen storage tank shell. The hydrogen storage alloy storage space is filled with hydrogen storage alloy, and the circulating heat exchange system is used for absorbing heat when the hydrogen storage alloy absorbs hydrogen and heating the hydrogen storage alloy when the hydrogen storage alloy releases hydrogen. According to the high-pressure composite metal hydride hydrogen storage tank and the hydrogen storage method thereof, a gas hydrogen storage gap is formed in the hydrogen storage tank, the size of a reserved gap can be adjusted according to the requirement of hydrogen storage mass density, hydrogen storage of different mass densities is achieved, the advantages of high mass density of high-pressure gas hydrogen storage and high volume density of solid hydrogen storage are fully combined, and the volume of the solid hydrogen storage part is adjusted, the purpose of storing more hydrogen under equal pressure is achieved.

Description

technical field

[0001] The invention relates to the technical field of hydrogen storage, in particular to a high-pressure composite metal hydride hydrogen storage tank and a hydrogen storage method thereof. Background technique

[0002] With the development of society, fossil fuels such as coal, oil, and natural gas can no longer meet the growing needs of human beings. At the same time, the use of fossil fuels has caused the deterioration of the ecological environment, such as the greenhouse effect. In addition, coal, oil, natural gas, etc. are non-renewable resources with limited reserves on the earth, and it is impossible for human beings to depend on them all the time. As a clean and efficient secondary energy source, hydrogen energy is considered to be an ideal energy source to replace traditional fossil fuels. In the hydrogen energy system, the safe storage of hydrogen is the most critical link.

[0003] As a bridge from production to utilization of hydrogen, hydrogen...
