An apparatus, method, and system for producing hydrogen gas by mechanical scraping of a surface of an aluminum-containing material, in the presence of an aqueous medium, the apparatus including: (a) a reaction chamber having a discharge port, and adapted to sealably contain the aqueous medium; (b) an aluminum-containing workpiece having a working surface; (c) a scraping mechanism having a brush adapted to contact the working surface, the workpiece and the scraping element disposed within the chamber, the surface and the scraping element adapted to move in a relative motion, whereby, in an operating condition, the scraping element scrapes against the working surface to effect a liberation of aluminum-containing particles from the workpiece, the chamber adapted to be substantially sealed with respect to an ambient environment, up to a superatmospheric pressure threshold, and further adapted whereby, during contacting of the aqueous medium and the particles within the chamber, the hydrogen gas is evolved and selectively discharged through the discharge port, when a pressure in the chamber exceeds the threshold.
