LNG industry, since the birth of China, its main function is peak regulation, supplement and substitution. In the future, its main functions will not change because of its high energy consumption. 1. LNG will become an alternative energy source for gasoline and diesel. Because of its environmental protection and superior price, liquefied natural gas will probably replace gasoline and diesel as the main fuel of automobiles. As I said just now, oil prices may go up. The national gasoline and diesel prices just mentioned on June 20th. Sooner or later, it will be in line with international standards, and there is a lot of room for price increases. According to the current lowest price, diesel is 6.23 yuan per liter, and gasoline is 6.23 yuan per liter. Among vehicle fuels, the highest price for converting LNG into natural gas is 3.5 yuan, and the mileage of 1 m3 natural gas is basically the same as that of 1 m3 gasoline, which shows the price advantage of LNG. Moreover, compared with CNG, LNG as a vehicle fuel has the advantages of longer driving mileage and less exhaust emissions. There is no doubt that LNG is environmentally friendly and will soon become an alternative fuel. After LPG and CNG, LNG is gradually applied to automobile fuel, which greatly promotes the process of changing oil into gas and makes up for the defect that stations cannot be built without pipe network. At present, LNG filling stations that have been built and put into operation in China include Beijing, Urumqi, Changsha, Guiyang, Hangzhou and other places, and Fuzhou, Xiamen and Hainan have also entered the pilot work. The development of LNG vehicles will certainly drive the LNG market. 2. Liquefied natural gas is more widely used in town gas peak shaving than pipeline natural gas. Market development and utilization can be carried out in places where natural gas pipelines have not arrived, and at the same time, it can make up for the problem that pipeline gas is not convenient to be fully laid in cities; As a civil fuel or power generation, with the change of seasons or other conditions, there will inevitably be fluctuations in quantity, which requires peaking devices, and LNG is most conducive to peaking storage. 3. The special industrial fuel replacing LNG has a high methane content, which determines its cleaner combustion. It is precisely because of the clean characteristics of LNG that its application in glass, ceramics, food processing and other industries will greatly improve the yield and increase the added value of products; From the comparison of calorific value of several fuels, LNG can be widely used in cutting, steel and other industries. 4. Liquefied natural gas will become an effective means to make up the national energy gap. Since 2008, the energy shortage in China has been increasing, and natural gas resources have rapidly replaced petroleum energy. However, with the exception of Russia, other neighboring countries have limited natural gas reserves, and pipeline natural gas import has been difficult to achieve, and one-way dependence is too strong. At present, the country is vigorously promoting the construction of LNG receiving stations and making full use of LNG. The gas-liquid ratio is large, which can make up for the demand of gaseous natural gas. At the same time, the country will also vigorously develop the development and utilization of coalbed methane to ensure the demand for natural gas resources, and liquefied natural gas is an effective way to accelerate the development, utilization and sales of coalbed methane.
