Abstract: A method is provided that generates hydrogen to power a hydrogen consuming device. Hydrogen is stored on-board a motorized vehicle, or the like, in a stabilized slurry of alkali metal borohydride particles and water. Upon demand from the hydrogen consuming device, such as a fuel cell, a portion of the slurry is conveyed to a reactor where borohydride particles are heated so that they hydrolyze to produce hydrogen gas and solid-phase by-products. The reactor includes a mixing element therein where the slurry is mixed and ground to expose unreacted borohydride particles from the solid reaction products. A separate grinding mechanism can be used to further crush and grind by-product particles for reaction efficiency and product transport. The solid-phase by-products are then stored in a by-products storage vessel whereas hydrogen gas is delivered to either a hydrogen buffer container for temporary storage or to the hydrogen consuming device.
