Hydrogen is a clean secondary energy source that plays an important role in promoting the region’s low-carbon mix transition. Currently, most of evaluations hydrogen production technologies terms consumption focus on efficiency, and fewer studies have been conducted at level exergy. In this paper, we use life-cycle approach quality coefficient method to assess discuss exergic efficiency three technology routes, namely from natural gas, propane dehydrogenation, green electricity, which were carried out China. gas was found lowest with losses mainly compression process, high-temperature chemical reactions, reduced catalyst activity. Propane dehydrogenation be about 16% more than hydrogen, compression. wind power has highest due electricity required run electrolyzer. By analyzing changes exergy China’s future supply, paper per unit will decrease 9.2 kg SC/kg H2 9.6 2030. The process China further improved as proportion electrolytic water structure increases.
