Current status of aluminium-water reaction for hydrogen production and cogeneration research

Abstract

In recent years, hydrogen production by reacting active metals with water has come to the fore, with aluminum having a high energy density and being stable and non-toxic. It is considered to be one of the suitable hydrogen-producing metals, and the reaction of aluminum metal powder with water can not only produce hydrogen, but also generate heat, which can be used for heating, and the hydrogen produced can be used as fuel for storage, and can also be directly circulated into the turbine, or indirectly circulated into the boiler to generate electricity for heating, and the electricity generated can be used to electrolyze alumina, which theoretically achieves the recycling of aluminum water. In this paper, we will describe three aspects of the aluminum water reaction, the preservation of aluminum nano-powder and the thermoelectric recycling system.
