Storing and transporting energy

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.
