摘要:

风电、光电的波动性是其发展的重要制约因素之一。国际上普遍认为,可再生能源制氢结合在役天然气管网掺氢输送的技术是解决大规模风光电消纳问题的有效途径之一。本文介绍了掺氢天然气管道输送应用示范项目,综述了管材氢相容性、设备掺氢适应性、管道运行安全保障以及标准体系建设4个方面的研究进展,并指出了目前发展掺氢天然气管道输送面临的问题与挑战。结合我国掺氢天然气管道输送发展现状,本文建议统筹规划掺氢天然气管道输送网络,因地制宜有序推进掺氢天然气基础设施建设,加强管材氢相容性、管网设备和部件掺氢适应性以及管道运行安全保障技术研究,逐步开展掺氢天然气输送技术应用示范,加快制定掺氢天然气管道输送规范标准,促进氢能产业发展。

Abstract:

The fluctuation of wind and solar power is one of the important constraints on their development. It is generally believed that hydrogen production using renewable energy and applying the in-service natural gas pipelines to transport hydrogen-natural gas mixtures is one of the effective ways to absorb large-scale wind and solar electricity. In this review, the demonstration projects of hydrogen-mixed natural gas pipeline transportation were introduced. The technical research and development status of hydrogen-natural gas mixture pipeline transportation were expounded from such 4 aspects as hydrogen-compatibility of pipeline materials, hydrogen-suitability of equipment, operation and safety, and construction of standard system, and the problems and challenges faced by the development of hydrogen-mixed natural gas pipeline transportation at present were concluded. Considering the current situation of hydrogen-natural gas mixture pipeline transportation in China, it is recommended to deploy hydrogen-natural gas mixture supply network as a whole, promote the construction of hydrogen-blended natural gas infrastructure in an orderly manner according to local conditions, and strengthen the research on hydrogen-compatibility of pipe materials, hydrogen-suitability of equipment and components, and operation safety security techniques. Furthermore, it is advisable to carry out application demonstration projects, and establish the standard system as soon as possible, so as to promote the development of the hydrogen energy industry effectively.
