The status quo and prospect of the alkaline water electrolysis system for hydrogen production are summed up in this paper with the focus on its modeling. Firstly， various ways of water electrolysis for hydrogen production are comparatively analyzed with the status quo of alkaline water electrolysis system for hydrogen production emphatically expounded： the technology of hydrogen production by alkaline water electrolysis has the features of low investment cost， long service life and large scale and is an important means to achieve the carbon peak target at current stage. Then， in the aspect of modeling for the alkaline water electrolysis system for hydrogen production， the influencing mechanisms of the energy consumption and gas purity of electrolytic cell as well as the temperature and system control are quantitatively analyzed. This study provides theoretical and technical supports for the development of hydrogen production technology by alkaline water electrolysis.
