The core technology of hydrogen energy is storage bottle

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

How is hydrogen stored in a solid state?

Currently, storing hydrogen through compression and liquefaction methods is the most mature and widely adopted approach. However, the high pressure of gaseous storage and the issue of evaporation loss in liquid storage have driven the continuous development of solid-state storage.

What are material-based technologies for hydrogen storage?

The material-based technologies for hydrogen storage is viewed as a safe method to store a big quantity of hydrogen in materials of smaller volume, under temperatures near ambient temperature and low pressure . Thus, these technologies are more appropriate for on-board application, as well as stationary uses.

Which technology is used to store hydrogen?

Nowadays, the technologies used to store hydrogen are classified as physically or material based. In the physical category, hydrogen might be stored as liquid or gas state while hydrogen is stored as solid form in material based. Several of these technologies have outgrown the laboratory stage and are used in prototype automobile. 2.1.

Why is hydrogen storage important?

There is a significant challenge in ensuring safe, economical, robust, compact, and reliable hydrogen storage methods. This is primarily attributed to hydrogen’s distinctive physical properties and the requirement to store substantial quantities to manage energy demand and supply.

What are the different types of hydrogen storage solutions?

Crucially, the development of compact, lightweight, safe, and cost-effective storage solutions is vital for realizing a hydrogen economy. Various storage methods, including compressed gas, liquefied hydrogen, cryo-compressed storage, underground storage, and solid-state storage (material-based), each present unique advantages and challenges.
