Abstract: Hydrogen energy has the characteristics of high mass energy density, diverse sources, rich application scenarios and zero terminal emissions at the end, etc. It is of great significance in ensuring national energy security, coping with climate change, promoting industrial upgrading and realizing high-quality development. This paper mainly introduced the main types of centralized hydrogen production, including natural gas reforming, coal gasification, industrial by-product hydrogen and electrolytic water, and analyzed the cost of hydrogen production. For hydrogen production from coal and natural gas, the technologies are relatively mature and widely used all over the world. The price of raw materials has a great impact on the cost. For industrial by-product hydrogen, it possesses the most market competitiveness at present. For hydrogen production from water electrolysis, it has the greatest development potential. If combined with renewable energy, the produced hydrogen belongs to “green hydrogen”, which is more in line with future green energy demand.

Key words: hydrogen energy, centralized hydrogen production, hydrogen production cost, hydrogen refueling station
