Abstract: Systems and methods for generating hydrogen from water consisting of reacting aluminum alloy powders with steam in the presence of an effective amount of promotor are provided. Aluminum powder is premixed with a dry solid-state promotor mixture before being exposed to high-temperature steam. Steam is introduced into a vessel called reactor, where the aluminum powder premixed with optimal ratio of promotors is contacted at pressure and temperature conditions to help the reaction between aluminum powder and water occurs completely, with 100% conversion in less than 15 minutes. Since the reaction occurs at high temperature condition, the heat released from the exothermic reaction between aluminum and steam is a “high-quality” heat, contributing to excess heat separation and making the most of the reaction heat, producing steam.
