Principle of hydrogen solid-state energy storage

Are first principle calculations useful for hydrogen storage materials?

First principle calculations have played a crucial role in advancing the understanding and design of these materials. This comprehensive review critically assesses the state-of-the-art in applying first principle methods to study various hydrogen storage materials, including binary hydrides, intermetallic hydrides, and complex hydrides.

Is hydrogen a viable storage method?

The broad use of hydrogen energy is hampered by concerns about compressed and liquified hydrogen’s safety, cost, and transportation. 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.

What is a solid-state hydrogen storage material?

The most extensively studied and often utilized solid-state hydrogen storage material is metal hydride. Chemically bonded hydrides are divided into three categories: (i) non-reversible complex hydrides, (ii) non-metal hydrides, and (iii) metal hydrides.

Why is solid-state hydrogen storage a key link of hydrogen economy?

Solid-state hydrogen storage, as a key link of hydrogen economy, stands out from HSTs by virtue of unique advantages mainly consisting of high gravimetric and volumetric hydrogen storage densities and safety in practical application such as fuel cell vehicles (FCVs) 4.

What is high-efficient solid-state hydrogen storage materials?

The great breakthrough in the performance of high-efficient solid-state hydrogen storage materials (SHSMs) will be an important support to promote industrial applications such as fuel cell vehicles (FCVs) and hydrogen refueling stations. In recent years, it has become a hot research field and derived a lot of material systems.

How is hydrogen stored?

Several methods of compressed storage, hydrogen liquefaction, chemical absorption, and physical adsorption have been proposed so far for storing hydrogen. The broad use of hydrogen energy is hampered by concerns about compressed and liquified hydrogen’s safety, cost, and transportation.
