Green Hydrogen Production by Mechanical Mixing of Aluminum with Water

A novel, green method for hydrogen (H2) production was studied; the method involves the mechanical mixing of aluminum (Al) with water (H2O). We examined the use of glass and stainless steel reactors. When the glass reactor was used, the induction period of the reaction of Al with H2O was long. The induction period decreased remarkably upon increasing the revolution rate; the optimal revolution rate was 1250 rpm. Furthermore, the reaction of Al with H2O in the stainless steel reactor was examined to investigate the practical feasibility of this H2 production method. In this case too an induction period was observed, and the induction period decreased upon increasing the reaction temperature and Al weight.
