The technology pathway to deliver renewable fuel gas in natural gas pipeline network is studied to further reduce carbon dioxide emission from consuming natural gas.Considering China's natural gas infrastructure situation and renewable fuel gas resources,adding hydrogen and biogas into China's natural gas pipeline network can increase the proportion of renewable energy delivered in China's natural gas pipeline network.Studies show that natural gas blending hydrogen technology has technical feasibility for large-scale promotion,and at present the volume ratio of hydrogen blended can reach 10％after technical evaluation.Biogas obtained after purification can meet the quality requirements for entering the natural gas pipeline network.By making full use of China's potential renewable fuel gas resources,it is expected that about 71 million tons per year of carbon dioxide emission can be reduced in 2030.Study result provides technical references for the green and low-carbon transition of natural gas use in China.
