中文摘要：

氢能以清洁、高效的特点被公认为未来最有潜力的能源载体,而天然气作为最清洁的化石能源正处于蓬勃发展的时期,全球已建和拟建的输送管网数量庞大,因此将H2掺入现有天然气管网实现储运和利用是近年来国内外研究和测试的热点。通过对全球天然气掺氢研究现状、典型项目案例、技术问题与应用优势等方面的探讨,认为虽然天然气管网掺氢存在一些问题,但仍是现阶段最好的一种高效储运方式和扩大氢能使用范围的路径。应积极推进天然气管道掺氢相关技术研究与攻关。

英文摘要：

Hydrogen energy is recognized as the most promising energy carrier of the future due to its clean and efficient characteristics. As the cleanest fossil energy resource, natural gas development is currently in its booming period. There are a huge number of pipeline network built and planned around the world, so it has been a hotspot of domestic and overseas research and testing in recent years to blend hydrogen into existing natural gas pipeline network for storage, transportation and utilization. In this paper, after exploring the research status of NCNG, typical project cases, technical issues and application advantages at home and abroad, we have reached the conclusion that HCNG is still the best way for efficient storage & transportation and expanding the unitization of hydrogen energy despite the existing problems. Related technical study and issue tackling shall be pushed forward proactively.
