碳中和背景下天然气掺氢技术现状及展望

Current Status and Prospects of Natural Gas Hydrogenation Technology under Carbon Neutrality

随着气候变化对环境保护的重视越来越高,各国纷纷进行碳中和的目标设定。在这样的政策背景下,天然气掺氢技术逐渐成为了一种清洁、环保的低碳技术。综述了天然气掺氢技术的现状和发展前景。掺氢技术主要涉及热解构反应、氢化反应和吸附剂膜等物质媒介吸氢反应等。虽然氢气在燃气领域存在技术成本、安全性、氢气来源等问题,但未来仍可通过技术创新、产业链完善以及政策支持等多种手段推动天然气掺氢技术不断发展和应用,实现能源的可再生及碳排放的减少,助推碳中和背景下能源革命的进程。

With the increasing importance of environmental protection due to climate change,countries have set the goals of carbon neutrality.Against this policy background,natural gas hydrogenation technology has gradually become a clean,environmentally friendly low carbon technology.The present situation and develop-ment prospect of hydrogen blending technology of natural gas are reviewed in this paper.Hydrogenation tech-nology mainly involves thermal decomposition reactions,hydrogenation reactions,and hydrogen adsorption re-actions using material media such as adsorbent membranes.Although hydrogen has technical difficulties in the gas field,Cost,safety,hydrogen source and other issues,hydrogenation technology can be continuously devel-oped and applied through technological innovation,industrial chain improvement,and policy support in the fu-ture,achieving renewable energy and reducing carbon emissions,and promoting the process of energy revolu-tion in the context of carbon neutrality.
