Abstract:
With China's active energy restructuring in recent years.and with the continued growth of the installed capacity of renewable enerey,the problem of absorbing abandoned electricity is becoming increasingly serous.The electrolytic-process-based clean chemical synthesis technology,thanks to its double role in chemical energy storage and clean production,is drawing attention gradually. In this paper,ammonia synthesis by hydro-electrolysis-induced hydrogen producton process is discussed,and comprehenslve comparison of hydrogen production by natural gas cracking and by hydro-electrolysis in ammonia synthesis is conducted in terms of such technical and economic characteristics as the energy consumpton . carbon emission, abandoned electricity absorption, economic production scale and investment conditions.etc.
Keywords: hydrogen production by natural gas cracking / hydrogen production by hydro-electrolysis / synthetic ammonia
