What materials can store hydrogen at room temperature

Which materials are used for storing hydrogen at room temperature?

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 H 2 storage performance of the aforementioned materials at room temperature.

What is the goal of hydrogen storage?

The goal is to pack hydrogen as close as possible, i.e. to reach the highest volumetric density by using as little additional material as possible. Hydrogen storage implies the reduction of an enormous volume of hydrogen gas. At ambient temperature and atmospheric pressure, 1 kg of the gas has a volume of 11 m3.

How can hydrogen be stored?

Hydrogen can be stored in a variety of physical and chemical methods. Each storage technique has its own advantages and disadvantages. It is the subject of this study to review the hydrogen storage strategies and to survey the recent developments in the field. 1. Introduction

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.

Are physical adsorbents suitable for hydrogen storage?

Owing to the low room temperature hydrogen capacities, physical adsorbents are not practically suitable materials for hydrogen storage. Compressed hydrogen in cylinders is a well-established technology and it is the most practical storage method for the stationary purposes such as in hydrogen based power plants.

What are the storage methods of hydrogen?

Besides conventional storage methods, i.e. high pressure gas cylinders and liquid hydrogen, the physisorption of hydrogen on materials with a high specific surface area, hydrogen intercalation in metals and complex hydrides, and storage of hydrogen based on metals and water are reviewed.
