Abstract

A new method of green hydrogen (H₂) production by mechanical mixing of aluminum (Al) with water (H₂O) using glass and stainless steel reactors was studied. There was a long induction period for H₂ production by the reaction of Al with H₂O using glass reactor. This induction period was remarkably decreased by increasing revolution rate and the optimal revolution rate was 1250 rpm. Furthermore, the reaction of Al with H₂O using stainless steel reactors was examined in order to get more information about practical use of H₂ production. In this case, the induction period was also observed, but this induction period was decreased by increasing reaction temperature and Al weight.
