Description

technical field [0001] The invention belongs to hydrogen production and storage technology, in particular to a continuous hydrogen production system from aluminum water. Background technique [0002] With the depletion of fossil energy and the increasingly serious environmental pollution, human beings have to pay attention to the development of sustainable energy. Hydrogen has the advantages of wide sources, high combustion calorific value, and cleanliness, so hydrogen energy is the best carrier for conversion between various energy forms. Since the hydrogen energy system is supported by a large number of water cycles, environmental pollution can be avoided, so hydrogen energy can be used to establish an energy system for a sustainable society. The research content of the hydrogen energy system mainly includes the preparation technology of hydrogen, the safe and efficient storage and transportation technology, and the development of application technology. At present, the ...
