Overview and prospect of ammonia synthesis with hydrogen produced via water electrolysis
With the rapid development of renewable energy technologies,ammonia synthesis with hydrogen produced via water electrolysis have received increasing attention.Since 1920s,this process has evolved from hydroelectric powered to the current wind/solar powered in over a century.This article comprehensively reviewed the history of ammonia industry,introduced the technological evolution and characteristics of diverse ammonia synthesis routes,e.g.via fossil energy,wind/solar power and grid electricity produced hydrogen.In addition,the current technical situation of ammonia synthesis with hydrogen produced via water electrolysis in China was deeply analyzed,and the future industrial scale of this route was also predicted.It was expected that the output value of the domestic synthetic ammonia industry would reach 317.3 billion CNY by 2030 and 790 billion CNY by 2050.Thoughts on the development of the domestic synthetic ammonia industry were proposed and two viable paths were outlined.Firstly,in regions with abundant and cheap renewable electricity,ammonia can serve as an effective means of power storage and consumption;Secondly,the green transformation of existing ammonia synthesis plants can be achieved by partially substituting fossil feedstocks with green hydrogen,thereby gradually unleashing and expanding the production capacity and environmental benefits of ammonia synthesis.
