Solid materials for hydrogen energy storage

What is solid-state hydrogen storage?

In contrast, solid-state hydrogen storage, utilizing physical or chemical interactions between hydrogen gas and storage materials to form solid solutions or hydrides, offers a compelling alternative.

What are the different types of solid-state hydrogen storage materials?

Nowadays under investigation are metal–organic frameworks (MOFs), metal-doped metal organic frameworks, covalent organic frameworks (COFs), clathrates, nanostructured carbon materials, metal-doped carbon nanotubes, and complex chemical hydrides as solid-state hydrogen storage materials .

Which material is used for solid hydrogen storage?

At present, hydrogen storage alloys are the most applied and studied material for solid hydrogen storage because they usually have high volume density, proper plateau pressure, rapid hydrogen absorption/desorption and good safety.

What are the different types of hydrogen storage?

Within solid-state storage, two primary categories emerge: physical hydrogen storage and chemical hydrogen storage and the principles of the two hydrogen storage methods are illustrated in the Fig. 2 . Physical hydrogen storage entails the adsorption of hydrogen gas onto the pores or surfaces of materials.

Are solid hydrogen storage materials viable?

Due to its superior transit and storage capabilities, solid hydrogen storage materials are viable hydrogen storage technique. There are numerous physical and chemical ways to store hydrogen. Each storage method has benefits and drawbacks of its own.

Why is hydrogen a promising storage method?

The safety, cost, and transportation of compressed and liquified hydrogen hinder the widespread application of hydrogen energy. Chemical absorption of hydrogen in solid hydrogen storage materials is a promising hydrogen storage method due to its high storage and transportation performance.
