Elements that can store hydrogen

What materials are used for hydrogen storage?

Storage of the hydrogen needs metallic materials that have the ability to absorb and desorb the hydrogen. In this chapter, we will discuss the characteristics of different types of alloys that are used in the hydrogen storage; also, we will show the suitable industrial applications for each alloy type.

How is hydrogen stored?

In physical storage, hydrogen is stored through compression and liquefaction. In chemical storage, hydrogen is stored through storing hydrides [ 4 ]. Metal hydrides are metals which have the ability to make a bond with hydrogen to produce new compound [ 5 ].

What is hydrogen storage based on?

Hydrogen storage can be divided according to whether it is based on physical or material storage (see Figure 1). Under physical storage, it is stored as a gas or liquid as a pure molecular compound with no significant physical or chemical bonding to other 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.

What are the advantages of using hydrogen storage materials?

Hydrogen storage materials can safely store the higher density of hydrogen compared to the gaseous and liquid hydrogen storage systems. Therefore, the systems using the hydrogen storage materials are considered as the most suitable for not only on-board application but also stationary uses [1,3–6].

What are the technologies for hydrogen storage?

Technologies for hydrogen storage can be divided into physical storage and chemical storage. In physical storage, hydrogen is stored through compression and liquefaction. In chemical storage, hydrogen is stored through storing hydrides [ 4 ].
