摘要
在当前全球能源转型和碳减排目标的背景下,掺氢天然气输送技术的开发和应用受到了广泛关注。这种技术通过将氢气与天然气混合使用现有的天然气管道基础设施进行输送,不仅有助于提高能源效率,还能促进清洁能源的使用。然而,氢气的引入也给天然气输送系统带来了新的挑战,本文探讨了氢致损伤的主要机理,综述了影响掺氢天然气管道氢致损伤的因素。此外,对当前用于探测和评估掺氢天然气管道损伤的技术进行阐述,通过比较和分析这些检测技术的优势和局限,指出未来研究的方向,包括提高检测技术的灵敏度和准确性,以及开发新的检测方法以应对掺氢天然气输送过程中的特殊挑战。本文旨在为掺氢天然气输送系统的安全运行提供科学依据和技术支持,对于推动氢能及天然气的安全、高效输送具有重要意义。
In the context of the ongoing global energy transition and carbon reduction objectives,there has been significant attention given to the deve-lopment and implementation of hydrogen-doped natural gas transmission technology.By blending hydrogen with natural gas for delivery through existing pipeline infrastructure,this technology not only enhances energy efficiency but also promotes the utilization of clean energy sources.However,the introduction of hydrogen also presents new challenges to the natural gas transmission system.This paper examines the primary mechanisms behind hydrogen-induced damage and summarizes the factors that influence such damage in pipelines carrying hydrogen-doped natural gas.Furthermore,it describes current technologies employed for detecting and evaluating damage in these pipelines.Through a comparative analysis of their advantages and limitations,future research directions are identified including enhancing sensitivity and accuracy of detection technologies as well as developing novel methods to address specific challenges encountered during transportation of hydrogen-doped natural gas.The objective of this paper is to provide a scientific foundation and technical support for ensuring safe operation of hydrogen-doped natural gas transmission systems,which holds great significance in promoting secure and efficient transportation of both hydrogen energy and na-tural gas.
