摘　　要：从能量计量、体积计量以及碳税等方面,对天然气管道掺氢进行经济可行性分析。以能量计量时,氢气成本需为天然气成本的28.6%~37.5%;以体积计量时,上游氢气生产成本需低于天然气。当下游用气费用不变,每掺1%氢气,中游售价需下降0.63%~0.72%;当中游利润不变,掺氢比为5%~20%时,氢气成本应低于天然气成本与0.62~0.63倍天然气利润之和;当两者均不变,氢气价格需低于天然气成本价格的37.1%~38.1%。考虑碳税为50~500元/t时,每掺1 m^(3)氢气,价格应再降低0.029~0.300元/m^(3)。The economic feasibility of hydrogen blending in natural gas pipelines is analyzed from the aspects of energy measurement,volume measurement and carbon tax.The calculation results show that when measured by energy,the cost of hydrogen needs to be 28.6%~37.5%of natural gas;when measured by volume,the upstream hydrogen production cost needs to be lower than natural gas.When the downstream gas consumption cost remains unchanged,the midstream sales price needs to drop by 0.63%~0.72%for every 1%hydrogen blended;when the midstream profit remains unchanged and the hydrogen blending ratio is 5%~20%,the hydrogen cost should be lower than the sum of the natural gas cost and 0.62~0.63 times the profit of natural gas;when both remain unchanged,the hydrogen cost needs to be lower than 37.1%~38.1%of natural gas.Considering that carbon tax is 50-500 Yuan/t,the price should be further reduced by 0.029-0.38 Yuan/m^(3) for every 1 m^(3) hydrogen blended.
