Patent ID: 8715583

Claim:
A system comprising: a pumpable hydrogen storage slurry, the pumpable hydrogen storage slurry comprising an inert liquid and reversible hydride formers, the reversible hydride formers having a hydrided state and a non-hydrided state, the pumpable hydrogen storage slurry not being subject to significant hydrogen evolution at room temperature and pressure when the reversible hydride formers are in a hydrided state; at least one charging device adapted to put non-hydrided reversible hydride formers of the pumpable hydrogen storage slurry in a hydrided state; at least one storage container, wherein the pumpable hydrogen storage slurry is conveyed from the at least one charging device to one or more storage containers; and at least one discharge device comprising: an inlet configured to covey the pumpable hydrogen storage slurry from one or more storage containers into the at least one discharge device, one or more heating elements adapted to heat the pumpable hydrogen storage slurry to a desorption temperature under anhydrous conditions, a desorption chamber where hydrogen gas desorbs from the pumpable hydrogen storage slurry to release hydrogen from the hydrided reversible hydride formers and form non-hydrided reversible hydride formers, wherein some of the inert liquid volatilizes in the desorption chamber, and a condenser configured to receive the desorbed hydrogen gas and the volatilized inert liquid and configured to condense at least a portion of the volatized inert liquid, and an outlet configured to convey the pumpable hydrogen storage slurry out of the desorption chamber.
