The utilization and development of natural gas are crucial to optimizing our country's energy structure and promoting ecological civilization. Representatives from the National Development and Reform Commission, the Ministry of Environmental Protection, the Ministry of Finance, and other ministries, as well as from State Grid Corporation of China, the five major power groups, the three major oil companies, gas enterprises, the Development Research Center of the State Council, and various research institutions and professional industry associations, among others, engaged in discussions to contribute wisdom to advancing the use and development of natural gas in our country.

One of the advantages of natural gas - safety

The gas density of natural gas is half that of air. Compressed natural gas is lighter than air, highly volatile, and not easily explosive. Methane, ethane, propane, and other components in natural gas are inherently non-toxic. In terms of safety, pipeline gas is superior to bottled gas. This is because pipeline gas utilizes a centralized storage and supply management system at gasification stations, which avoids the safety risks associated with the scattered storage of bottled gas, liquefied natural gas tanks, and self-provided usage. The indoor pressure of pipeline gas is only 1/130 of that of tap water and 1/170 of bottled gas. The storage capacity of the gas pipeline itself is very small, approximately 1/3000 of bottled gas when calculated based on a 12-meter indoor pipeline per household. In case of a leak or fire caused by other reasons, simply closing the main valve or the unit riser valve indoors can cut off the gas supply and eliminate the danger. In contrast, in similar situations, it is difficult to effectively close or remove the oil liquefied gas cylinder, which can easily lead to explosions.

One of the advantages of natural gas – Economic

Economical and cost-effective is one of the advantages of natural gas, which is also a reason for the rapid nationwide adoption of pipeline natural gas. When comparing the market prices of pipeline natural gas with other fuels, using pipeline natural gas can save at least 25% to 35% on monthly costs under the same usage volume (calorific value) compared to bottled LPG. This not only eliminates the expenses of purchasing and regularly inspecting steel cylinders but also the costs associated with transporting and replacing liquefied gas in daily life. The cost of using natural gas is more than 35% cheaper than electricity, and about 25% to 35% cheaper than diesel or heavy oil.  The third advantage of natural gas – environmental friendly  Natural gas is composed of 98% methane, a simple molecule (CH4) made up of one carbon atom and four hydrogen atoms.
