摘　　要：氢气能源在利用过程中没有任何“碳排放”,环保优势突出,未来具有广阔的发展前景。如果利用现有天然气管道进行掺氢输送,是将来大规模利用氢气的一种有效思路,但由于氢气容易导致管材失效,且氢气相比于天然气更容易扩散且爆炸极限更宽,所以管道掺氢输送也面临若干风险。本文从现有管道、介质泄漏及其火灾爆炸风险等几个方面展开分析,探讨现有天然气掺氢输送的可行性。There is no“carbon emission”in the utilization of hydrogen energy,which has outstanding environmental protection advantages and broad development prospects in the future.If the existing natural gas pipeline is used for hydrogen-doped transportation,it is an effective way to use hydrogen on a large scale in the future.However,because hydrogen is easy to cause pipe failure,and hydrogen is easier to diffuse and has a wider explosion limit than natural gas,the pipeline hydrogen-doped transportation also faces several risks.This paper analyzes the existing pipelines,medium leakage and fire and explosion risks,and discusses the feasibility of hydrogen-mixed transportation of existing natural gas.
