In the recent past, LNG has been used as a clean energy source encouraged and promoted by the state and has been used more and more widely in transportation. All automobile manufacturers have also adopted LNG vehicles as a strategic planning product sequence in order to obtain greater sales volume. However, at present, the natural gas industry chain lacks national macro-control, the pricing mechanism for natural gas for vehicles is not yet perfect, and the instability of price fluctuations and gas prices. Many users question whether the use of LNG at this stage can bring stable economics to themselves.
LNG bus
Wonderful drama has started
On August 31, the first batch of Futian Ouhui LNG buses purchased by Beijing Bus Group formally went into operation. It is reported that Beijing Public Transport Group and Foton Motor have signed a sales contract for 3,012 LNG buses, and it is part of the operation of the vehicles. The LNG city buses that were put into operation this time are all new energy bus products developed by Futian Ouhui for the exclusive research and development of Beijing Public Transport and insisting on the technology, green, low-carbon and environmentally-friendly concept of making cars. This action not only marks the further expansion of the scope and number of “green buses†for Beijing residents, but also plays an important role in the improvement of atmospheric environment and the implementation of the “Clean Air Action Plan†in Beijing.
According to industry sources, since LNG passenger cars do not produce harmful toxic substances such as sulfur, lead, and benzene, the emission of “National IV†and above is basically free of PM emissions, and the environmental protection effect is excellent. At the same time, it also takes into account the economy and safety of operations. It is an important direction for the development of public transportation. Previously, the environmental protection department carried out tail gas testing specifically for LNG passenger cars. According to its year-long operation tracking report, the emissions of LNG passenger cars have reduced carbon monoxide by 97%, hydrocarbons by 72%, nitrogen oxides by 80%, and carbon dioxide reduction. 24%, SO2 reduction of 90%, car noise reduction of 40%, benzene, lead, dust, etc., reduced by 100%.

Keep going smoothly
In recent years, the self-ignition and collision accidents of buses have left people with a hard time. How to ensure the safety of public transportation has become one of the topics of concern to everyone. Public transport experts believe that LNG buses have greater advantages in safety compared to fuel buses.
The reporter learned that, like the Ouhui LNG passenger car, it adopts a highly integrated system design. The gas cylinder is in a separate sealed compartment, isolated from all wiring harness appliances, eliminating the occurrence of hidden dangers from the source; at the same time, the leak prevention device of the gas capsule compartment can effectively avoid Leaking gas accumulation will not cause explosion; Ouhui LNG bus also takes the lead in adopting Class A “non-combustible†materials. Compared to the “flame-retardant†materials of ordinary passenger cars, it can be said that “good cars are not afraid of fireâ€. At the same time, the engine room is also equipped with Leakage alarm devices and automatic fire extinguishing devices, and linked with the monitor display at the dashboard, the "passive safety" coefficient has greatly improved.
Promotion
The road twists and turns bright prospects
When LNG was in full swing, the CNPC issued a document a few days ago, requesting that the gas supply prices of LNG plants in various regions be raised to the highest prices for non-residential consumers. In view of the fact that more than 70% of the gas resources of domestic LNG plants have been imported from China National Petroleum Corporation, some analysts have pointed out that once the price of raw gas supplied by CNPC increases, the cost pressure on LNG production companies will increase dramatically, and their ex-factory prices will rise sharply, resulting in lower capacity. The users may gradually fade out of the market, and the domestic LNG downstream market will face a “shuffleâ€.
Industry insiders believe that the future development of LNG industry needs to see the construction progress of gas stations, technical progress of LNG cylinders, and the country's drive for LNG. From this point of view, looking at the 12th Five-Year Plan for natural gas development seems to give us enough confidence. The plan points out that steadily advancing the construction of LNG receiving stations is one of the key tasks. It also proposes to preferentially expand the storage capacity of existing LNG receiving stations and to appropriately develop small LNG liquefaction and gasification stations. Therefore, under the strong support of the policy level, the LNG industry should have sufficient confidence and high expectations for future development.

LNG (LiquefiedNaturalGas), namely liquefied natural gas, is cooled from -162°C by gas cooled natural gas under normal pressure, and has large calorific value and high performance. In recent years, LNG has been listed as the preferred fuel by many countries, and it has grown at a rapid rate of about 12% per year, making it one of the fastest growing energy industries in the world. Due to the very significant overall benefits, the promotion of LNG energy has become a general trend in the transportation industry. First, vehicles using LNG can reduce harmful gas emissions by more than 90% compared with fuel vehicles. Second, LNG's price is lower than that of gasoline and diesel, which can greatly reduce the cost of use. Third, LNG is high in purity and fully burned. Carbon deposition can effectively reduce the wear of parts and prolong the service life of the engine.
