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/m3 for every 1 m3 hydrogen blended.
