Gaseous Hydrogen Storage

ByS.A. Sherif and Frano Barbir

Because of hydrogen’s low density, its storage always requires relatively large volumes and is associated with either high pressures (thus requiring heavy vessels) or extremely low temperatures and/or a combination with other materials (much heavier than hydrogen itself). Table 16.1 shows achievable storage densities with different types of hydrogen storage methods. Some novel hydrogen storage method may achieve even higher storage densities but have yet to be proven in terms of practicality, cost, and safety.
