Storing And Transporting Energy

Abstract

Among other things, hydrogen is released from water at a first location using energy from a first energy source; the released hydrogen is stored in a metal hydride slurry; and the metal hydride slurry is transported to a second location remote from the first location.

1 . (canceled) 
     
     
         2 . A hydrogen storage slurry comprising an inert liquid and a hydride, wherein the hydride comprises reversible hydride formers having a non-hydrided state and a hydrided state, and wherein the reversible hydride formers have a particle size from about 1 micron to about 50 microns. 
     
     
         3 . The hydrogen storage slurry of  claim 2 , wherein in the non-hydrided state, the reversible hydride formers comprise a metal or a metal alloy. 
     
     
         4 . The hydrogen storage slurry of  claim 2 , wherein in the non-hydrided state, the reversible hydride formers are magnesium metal. 
     
     
         5 . The hydrogen storage slurry of  claim 2 , wherein in the hydrided state, the reversible hydride formers are metal hydrides. 
     
     
         6 . The hydrogen storage slurry of  claim 2 , wherein the hydride is made solely of magnesium hydride. 
     
     
         7 . The hydrogen storage slurry of  claim 2 , wherein the inert liquid comprises mineral oil. 
     
     
         8 . The hydrogen storage slurry of  claim 2 , wherein the hydrogen storage slurry further comprises magnesium, mineral oil, and a dispersant. 
     
     
         9 . The hydrogen storage slurry of  claim 8 , wherein the dispersant comprises a triglyceride, a polymeric dispersant, or a combination thereof. 
     
     
         10 . The hydrogen storage slurry of  claim 2 , wherein the reversible hydride former is in powder form, and wherein the powder further comprises mineral oil and a dispersant. 
     
     
         11 . The hydrogen storage slurry of  claim 10 , wherein the powder has been milled. 
     
     
         12 . The hydrogen storage slurry of  claim 2 , wherein the hydrogen storage slurry is not subject to significant hydrogen evolution at room temperature and pressure when the reversible hydride formers are in a hydrided state. 
     
     
         13 . The hydrogen storage slurry of  claim 2 , wherein the pumpable hydrogen storage fluid includes a concentration of between 40 weight percent and 80 weight percent of the reversible hydride formers.
