Title: System for exchange of hydrogen between liquid and solid phases

Patent ·
OSTI ID:6540112

This patent describes the process of selectively storing and releasing hydrogen in metal hydride formers that reversibly react with hydrogen to form hydrides and release hydrogen, comprising in combination the steps of: (a) suspending particles of a metal hydride former that can reversible absorb and desorb hydrogen in an inert liquid selecting from the group consisting of silicone base liquids, saturated organic liquids which may be fluorinated, kerosene, and water, to form a slurry; (b) agitating the slurry in the presence of hydrogen gas at a pressure above the equilibrium absorption pressure of the metal hydride former so that the metal hydride former absorbs the hydrogen to form the metal hydride and establish the H/sub 2/ storage mode of operation of the process; and (c) agitating the slurry, containing the previously formed metal hydride, in the presence of hydrogen gas at a pressure below the equilibrium desorption pressure of the metal hydride to decompose the metal hydride into H/sub 2/ gas and the metal hydride former.
