Description

technical field [0001] The invention belongs to the technical field of bioenergy utilization, and in particular relates to a Hangjin 2 # Soil hydrogen storage molecular sieve hydrogen storage device. [0002] The present invention also relates to the above-mentioned Hang Jin 2 # Preparation method of soil hydrogen storage molecular sieve. [0003] The present invention also relates to a method of using the above-mentioned hydrogen storage device. Background technique [0004] The increasing depletion of global non-renewable energy and environmental pollution pose a serious threat to human survival and sustainable development. The development of clean energy with high added value has become a research hotspot. As an efficient, clean and renewable energy, hydrogen has attracted increasing attention. [0005] The hydrogen energy system mainly includes three links: hydrogen production, storage and transportation, and application. Among them, the storage of hydrogen is the ke...

AI Technical Summary

Problems solved by technology

[0006] (1) Gas hydrogen storage technology, that is, compressing hydrogen and storing it in a high-pressure container, but the volume of hydrogen stored in the cylinder is small, the hydrogen storage capacity is small, and there is a danger of explosion;

[0007] (2) Liquid hydrogen storage technology, that is, hydrogen gas is liquefied and stored in an insulated container. The disadvantage is that the liquid storage tank is very large, requires excellent heat insulation devices to insulate heat, and is prone to leakage;

[0009] However, the current research on solid hydrogen storage technology mainly focuses on the discovery of new materials or the modification of original materials, and there are few reports on large-scale or industrialized high-adsorption solid hydrogen storage devices.
