Hydrogen Storage: A Wide Range of Solutions

Hydrogen storage plays a central role in the hydrogen energy value chain. Efficient, economical and safe methods are essential to increase the gas’ volume density and enable the sector’s deployment.

Hydrogen Storage analyzes the various ways of storing hydrogen, whether in a gaseous state in pressurized reservoirs or geological structures, in a liquid state through the formation of ammonia or hydrogen-carrying organic liquids, or in a solid state in hydrogen-containing inorganic compounds such as metal hydrides and regenerable hydrides, or by adsorption into porous materials.

For each method, concepts are presented according to the processes used or the storage materials involved. Their advantages and disadvantages, as well as the main obstacles and challenges to be overcome, are analyzed.

This book provides an overview of the various storage solutions currently available, helping operators to choose the most appropriate method for a given application.
