Description

Technical Field

[0001] The invention relates to the technical field of pipeline transportation, and in particular to a pipeline transportation system for solid-state storage of hydrogen produced by electrolysis of water. Background Art

[0002] Hydrogen production by water electrolysis and solid-state storage are important links in the hydrogen energy industry chain. Together, they constitute an efficient conversion and storage system from renewable energy to hydrogen energy. Solid-state storage is an important way to store hydrogen energy. It uses solid-state hydrogen storage materials to store hydrogen in a solid form. Compared with traditional gaseous and liquid hydrogen storage, solid-state hydrogen storage has the advantages of high volume hydrogen storage density, good safety, and long storage time.

[0003] Metal hydrides are the mainstream technology route for solid-state hydrogen storage. They combine with hydrogen through chemical reactions to generate metal hydrides, thereby realizing hydrogen storage. When needed, these metal hydrides can be decomposed by heating and other methods to release hydrogen for use. When using metal powder particles for hydrogen storage, hydrogen is directly transported to the inner cavity of the storage tank through a pipeline, and then the metal powder particles are placed in the storage tank. Such storage is likely to cause insufficient reaction between hydrogen and metal particles, resulting in the need to add a stirring device to stir the particles. The stirred particles cannot guarantee full contact with hydrogen, and as the number of metal particles in the storage tank increases, stirring contact becomes increasingly difficult, and the transportation and circulation of hydrogen in the pipeline cannot be fully utilized, affecting the solid-state hydrogen storage effect of water electrolysis to produce hydrogen.
