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 do we need a large storage system for hydrogen?

application impractical. Hydrogen is frequently liquefied or compacted to improve its density since it has a low volumetric energy density (0.0899 kg/m 3) under atmospheric circumstances. However, these technologies have enormous prices, and safety concerns, and call for large storage systems.

Which materials are suitable for hydrogen storage by physical adsorption?

The materials which are candidates for the hydrogen storage by physical adsorption include microporous carbon structures, metal organic frameworks, and zeolites. These adsorbent materials are mostly well developed and have high surface area. As adsorption is a surface phenomenon, high surface area is undoubtedly a requirement.

What is chemical hydrogen storage materials research?

Chemical hydrogen storage materials research focuses on improving volumetric and gravimetric capacity, improving transient performance, reducing release of volatile impurities, and developing efficient regeneration processes for the spent storage material.

What are the challenges and opportunities facing hydrogen storage technologies?

In addition, this paper highlights the key challenges and opportunities facing the development and commercialization of hydrogen storage technologies, including the need for improved materials, enhanced system integration, increased awareness, and acceptance.
