Abstract:

In the current context of "dual carbon", hydrogen energy will gradually develop into an important component of world energy due to its characteristics of cleanliness, zero carbon, high efficiency, and abundant reserves. The long-distance pipeline transportation technology of hydrogen energy is a key technology for its industrial scale application and also a bottleneck technology that restricts its development. Pipeline transportation is considered the best way to transport hydrogen energy over long distances, with the characteristics of safety, efficiency, and energy conservation. This paper provides a comprehensive overview and summary of the latest developments in hydrogen pipeline transportation technology. The analysis shows that in the research of hydrogen energy pipeline transportation technology in China, due to hydrogen blending ratio, safety issues, such as pipe compatibility, leakage and explosion, and incomplete supporting processes and equipment, the technical specifications and risk assessment system for hydrogen energy long-distance pipelines have not been fully established, and the large-scale application of hydrogen energy has not yet been realized. The key to achieve large-scale application of hydrogen energy lies in the breakthrough of core technology for hydrogen pipeline transportation and the establishment and improvement of a standard system for hydrogen pipeline transportation technology.

摘要：

在当前“双碳”背景下，氢能因其清洁、零碳、高效、储量丰富等特点，将逐渐发展成为世界能源的重要组成部分。氢能的长距离管道输送技术是其产业规模化应用的关键技术，亦是制约其发展的瓶颈技术。管道输送被认为是氢能长距离运输的最佳方式，具有安全、高效、节能的特点。本文对氢能管道输送技术最新进展进行全面的概述和总结，分析表明：在国内对于氢能管道输送技术研究中，受限于掺氢比、安全性和相关技术工艺、设备不完善等问题，氢能长输管道技术规范标准和风险评估体系尚未完整建立，氢能的规模化应用尚未实现；实现氢能大规模应用，关键在于氢能管道输送核心技术的突破和氢能管道输送技术标准体系的建立和完善。
