Feasibility study of Mg Scrap Hydrolysis for Hydrogen Generation using HCl by Energy Cost Analysis

Due to the importance of energy and the tendency to find a renewable source of energy, the energy field has been linked to all studies areas to find the optimal methods for the energy production. The concern about environmental pollution and the needs of human for the clean energy supply have attracted researchers' attention to search about new technology to utilize the solids waste from the electronic and automobiles industries in such a way to produce energy which can be advantageous in two ways; this can manage the solid waste and produce source of energy. In this study, Mg scraps have been used for the hydrogen generation via hydrolysis. The total energy cost has been calculated to predict the performance of the process depending on the cost of chemicals that have been used to generate H₂ gas. Hydrolysis process was conducted with different concentrations of HCl to study the effect on the hydrogen gas generation using Mg scraps. This work optimizes the process of using Mg scraps to produce H₂. The results showed a significant increase in the hydrogen gas generation with the same total cost after increasing the Mg scrap weight from 3.4g to 15g with 50ml amount of HCl.
