摘要
氢能具有质量能量密度大、来源多样化、应用场景丰富、终端零排放等特点,在保障国家能源安全、应对气候变化、推动产业升级、实现高质量发展等方面具有重要意义。本文重点介绍集中式制氢的主要类型,包括天然气制氢、煤制氢、工业副产氢和电解水制氢,并分析其制氢成本。对于煤制氢和天然气制氢,技术比较成熟,全球范围内应用广泛,原料价格对成本影响较大;对于工业副产氢,现阶段最具市场竞争力;对于电解水制氢,发展潜力最大,若与可再生能源结合,生产的氢气属于“绿氢”,更符合未来绿色能源需求。
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.
