Pipeline transportation of hydrogen-blended natural gas is an effective means to solve the problems of economical, large-scale, long-distance and cross-regional transportation of hydrogen in the process of its utilization.Herein, the analysis of knowledge graph clustering, co-presenting and highlighting was performed to the references related to pipeline transportation of hydrogen-blended natural gas at home and abroad from 2006 to 2022, so as to sort out the research status and predict the evolution trend in the future. The results show that: great importance is attached by major developed countries in the world to the research on the pipeline transportation of hydrogen-blended natural gas, and the research on pipeline transportation of hydrogen-blended natural gas is relatively mature in foreign countries. The research on pipeline transportation of hydrogen-blended natural gas in China was started relatively late and it is generally in the preliminary stage though some progress has been made. From the perspective of future trends, in China, more attention is paid to the research on hydrogen refueling stations, hydrogen embrittlement, hydrogen energy, and the equipment and environment closely related to pipeline transportation of hydrogen-blended natural gas, while foreign researches mainly focus on the pipeline material, and the systematic and modeled solutions for pipeline transportation of hydrogen-blended natural gas.
