摘要
分析和比较了煤制氢、天然气制氢、电解水制氢和焦炉煤气制氢几种常见制氢方法的生产成本.基于平准化氢气成本模型的研究结果表明,煤制氢在目前条件下经济性最好,电解水制氢在目前平均电力价格下经济性不及煤制氢;原料价格和电力价格是制氢成本的关键影响因素;若使用可再生电力,2030 年左右电解水制氢在经济性方面将具有竞争力.研究结果可为降低生产成本、提高经济效益和推动氢能产业发展提供决策依据.
Abstract
The costs of several common hydrogen production routes,including coal gasification,natural gas reforming,water electrolysis and recovery of by-product hydrogen from coke oven gas are analyzed.According to the levelized cost of hydrogen model,hydrogen production coal gasification has the best economic efficiency currently.Producing hydrogen by water electrolysis is not economical under current electricity prices.Feedstock price and electricity price are the key factors influencing the cost of hydrogen production.If renewable electricity use is considered,hydrogen from water electrolysis will be economically competitive around 2030.These findings serve as a foundation for decision-making basis to reduce hydrogen production costs,improve economic efficiency,and promote hydrogen industry development.
