Abstract: 
This study explores a method for hydrogen production via the chemical dissolution of aluminum alloy AK7 in alkaline solutions with NaF and NaCl activators. The optimized electrolyte composition and activator concentrations significantly enhance the aluminum dissolution rate, leading to efficient hydrogen evolution. The proposed method offers advantages in sustainability, economic efficiency, and minimal environmental impact. A comprehensive analysis of the kinetic parameters was conducted, establishing optimal process conditions. The developed technological scheme can be integrated into emergency power supply systems for water supply facilities, providing several hours of autonomous operation of water supply equipment under emergency and extreme conditions.
