Which adsorbent materials store hydrogen at room temperature?

Hydrogen storage capacities of different adsorbent materials can be found in Table 1. Carbonaceous materials, MOFs, zeolites, clathrates are some of the materials used for storing hydrogen through an adsorption mechanism. The following sections give an overview of the H2 storage performance of the aforementioned materials at room temperature.

What are the limitations of hydrogen sorbents as H2 storage materials?

In these classes of materials, the hydrogen storage capacity mainly depends on the surface area and pore volume. The main limitation of use of these sorbents as H 2 storage materials is weak van der Waals interaction energy between hydrogen and the surface of the sorbents.

Which hydride is best for hydrogen storage?

Hydrides chosen for storage applications provide low reactivity (high safety) and high hydrogen storage densities. Leading candidates are lithium hydride, sodium borohydride, lithium aluminium hydride and ammonia borane.

Why is hydrogen a good material to store in solid form?

It occurs relatively at (i) low pressures compared to the compressed gas, and (ii) high temperatures compared to the low-temperature liquid . Materials storing hydrogen in solid form should offer good kinetics, reversibility, affordability, and high storage capacity at ambient conditions.

Can organic polymers be used for storing hydrogen?

The hydrogenated polymers released hydrogen in the presence of catalysts at mild conditions. The potential of using organic polymers in the quest for nding new types of hydrogen-carrying and fi -storing materials that are very safe and portable is suggested.

How do porous materials store hydrogen?

Porous materials, such as activated carbon and metal-organic frameworks (MOFs), store hydrogen through physical adsorption on the surfaces of materials. The weak interactions between hydrogen and the material allow reversibility of the hydrogen storage and release, but they also lead to a low hydrogen density in ambient conditions.
