Natural gas is a clean and efficient fossil energy source, and the main component is methane. The natural gas industry covers the entire industrial chain from natural gas exploration, development, production, purification, storage, transportation to sales and utilization. It occupies an important position in the global energy structure, and its importance is becoming more and more prominent as the requirements for environmental protection and energy cleaning continue to increase. 

 The natural gas industry is a key industry with the dual attributes of "energy security" and "low-carbon transformation". Its industrial chain is long, technology-intensive and has a wide influence. Under the global "dual carbon" goal, natural gas will play the role of "transitional energy" for a long time, while upgrading to "low-carbon and high-value" through technological innovation. For China, the core task of the natural gas industry is to "ensure supply security" and "promote low-carbon transformation" in parallel to provide support for energy structure optimization and high-quality economic development.
