Patent number: 8889097Abstract: An on-board hydride storage system and process are described. The system includes a slurry storage system that includes a slurry reactor and a variable concentration slurry. In one preferred configuration, the storage system stores a slurry containing a hydride storage material in a carrier fluid at a first concentration of hydride solids. The slurry reactor receives the slurry containing a second concentration of the hydride storage material and releases hydrogen as a fuel to hydrogen-power devices and vehicles.Type: GrantFiled: January 9, 2012Date of Patent: November 18, 2014Assignee: Battelle Memorial InstituteInventors: Kriston P.
