Hydrogen Storage

Abstract

Translate Article

Most hydrogen is used locally where it is produced or generated, and it is, generally speaking, technically difficult and expensive to not only store but also transport hydrogen safely other than by pipeline. At the present time, hydrogen storage, especially at large scale or using “bulk” storage approaches, needs further development and investment before they are ready for broad deployment. Storage of materials, particularly gases and liquids, requires the use of tanks and reaction vessels for a wide variation of temperature and pressure conditions. This chapter presents a few principles employed in industrial settings, particularly in chemical process industries. Methods for storage currently available or under study are: high-pressure gas tanks; cryogenic liquid tanks; underground storage salt caverns; adsorption in metal hydrides; and bonding with liquid organic hydrogen carries. The most common method to store hydrogen in gaseous form is in steel tanks.
