HySafe Wiki | BRHS / Storage Introduction

Storage is a challenging issue that cuts across production, delivery and end-use applications of hydrogen as energy carrier. Storage constitutes a key enabling technology for the hydrogen economy, as a main appeal of hydrogen, compared to the already established clean energy vector electricity, is that it is more readily stored and transferred. Hydrogen storage systems will thus be present in both stationary and mobile or portable applications.

There are several “storage options” to choose from: gaseous, liquid, “solid-state” and other novel media. Figures 1 and 2 illustrate the gravimetric and volumetric densities achieved or expected for the various storage options in on-board vehicle applications.
