As a kind of clean energy, the carbon dioxide emission of natural gas is only 60% of that of coal and 80% of that of oil, which plays a very important and special role in the transition process of energy utilization from high carbon to low carbon. At present, China attaches great importance to the development of renewable energy such as solar energy and wind energy, and focuses on the transformation of energy structure by expanding the use of natural gas Industry has become an important hand in the transformation and adjustment of energy structure.
