Mist, still a key word this year. The Central Finance Department has allocated 5 billion yuan for the control of air pollution in Beijing, Tianjin, Hebei and the surrounding areas, and once again shows that the air quality problem cannot be delayed.
For the sake of environmental protection, the public transport sector is vigorously implementing the strategy of energy conservation and emission reduction. Purchasing or renewing buses in various regions throughout the country, new energy and clean energy models have undoubtedly become the first choice. Purchasing new energy or clean energy models has become a major trend for future public procurement. "Currently, in the three categories of pure electric, hybrid, and natural gas (including LNG liquid natural gas and CNG gaseous natural gas), which are mainly promoted in the field of buses, natural gas vehicles have the widest range of promotion." Huanghai Bus Brand Communication Lin Chongfu told reporters.
In fact, this is the case. Natural gas buses have a high market share in most regions. It is reported that the implementation of the “Blue Sky Project†in Liaoning Province has made it clear that future bus purchases or updates will use natural gas and new energy vehicles. In the background of “gasification of Liaoningâ€, natural gas buses have won the favor of most regions because of their many advantages such as emission performance, acquisition cost, and safety and reliability.
Yellow Sea natural gas bus: wide spread and mature technology
In the face of PM2.5, automobile exhaust, which is the main source of urban pollution, has attracted much attention. Since emissions of natural gas fuels do not include suspended particulates, the emissions of nitrogen oxides and hydrocarbons also have absolute advantages over gasoline and diesel, so natural gas vehicles are often referred to as “cars in the true sense of environmental protectionâ€.
At present, the most widely promoted range of buses is the natural gas bus. “Compared to traditional energy buses, the acquisition cost of natural gas vehicles will increase slightly,†Lin Chongfu told reporters. “But compared to hybrid vehicles and pure electric vehicles, natural gas buses have advantages in the acquisition cost.†It is understood that Due to the issue of acquisition costs, the promotion of hybrid vehicles and pure electric buses is greatly affected by the new energy subsidy policy.
Natural gas buses are not new, and their safety performance and manufacturing technology are relatively mature. Natural gas vehicles at home and abroad have a history of more than 60 years. It is reported that Huanghai buses started to engage in natural gas buses in 2006 and have many years of research, testing and marketing. Operating experience, its technology is mature, safe and reliable. According to reports, in order to ensure the safety and convenience of its operation, Huanghai Bus has deployed multiple safeguards such as a natural gas parameter display, gas leak alarm, and engine anomaly alarm on the vehicle. In the engine compartment, equipped with automatic sprinkler fire extinguisher, when the local temperature in the engine compartment is too high, the automatic fire extinguisher will blast, generate a lot of inert gas, while spraying a large number of ultrafine fire extinguishing powder, at the same time, the Yellow Sea has a number of national special technology , to ensure the safe operation of the vehicle and the safety of passengers.
Natural gas bus: favored by users, significant energy saving and emission reduction
“At the end of 2011, 100 10m and 11m Yellow Sea LNG buses that were once purchased by Dandong Bus were officially launched. This is the first time that Dandong Public Transport has used LNG buses in the past 60 years.†Wang Chengchun, deputy general manager of Dandong Public Transport Corporation, told reporters “In the past one year, the emission reduction effect has been obvious. Compared with traditional energy sources, the harmful emissions of LNG vehicles can be reduced by 85% and the operating costs can be reduced by 15 to 20%.†Wang Chengchun also added that it has purchased new products this year. 8 meters of Yellow Sea natural gas (LNG) bus models, has formed a different length of public transportation products, to solve the old vehicle in Dandong, black smoke, low capacity and other issues. According to the latest statistical data report, currently Dandong ranks first in space quality in Liaoning Province.
It is reported that as early as 2010, the National Development and Reform Commission has identified Liaoning as one of the first low-carbon pilot provinces in China, and the Ministry of Transport has also identified Liaoning as one of the first pilot provinces for the promotion and use of LNG vehicles in China. To this end, from this year onwards, Liaoning has started to promote the use of LNG liquefied natural gas. In addition, Liaoning Province began to implement the “Blue Sky Project†last year. In the two measures of gasification of Liaoning and the development of green traffic, it also mentioned the need to vigorously promote new energy vehicles. It is clear that “new and updated buses should all use natural gas, etc.†Clean Energy Vehicles.†Not only that, but also in the heavy-duty transport sector, the promotion of LNG applications is also encouraged. Obviously, the purchase of buses in Liaoning Province in the future has been tilted toward natural gas vehicles at the policy level. With the continuous improvement of the province's LNG and liquefied natural gas filling stations at the transport nodes, natural gas vehicles are bound to have considerable development prospects in Liaoning.
The development of natural gas buses has become a good measure for controlling haze and improving air quality in the public transport sector and is worth learning from.
Natural Gas Bus: Future Bus Purchase Trends
Looking at the current situation of the promotion of new energy vehicles in the bus sector: Hybrid power is affected by the subsidy policy, promotion of use is to a certain extent hindered; the purchase cost of pure electric buses is high, limited by the battery technology and other issues, not previously in the country Apply scope. At present, in order to improve the worsening air quality in most regions, more bus companies have turned their attention to clean energy natural gas vehicles. Some experts said that natural gas models will become a trend for the development of buses in the future.
It is understood that the market share of natural gas buses is also rising. In addition to Liaoning Province has such a large promotion efforts, the most worth mentioning are the natural gas buses in various regions of Hebei Province. Such as Shijiazhuang Bus, since 2004 began the introduction of natural gas buses, as of now, has invested 1.362 billion yuan in total, procurement of natural gas buses 3311, greatly improving the conditions of the people's travel, significantly reducing emissions of exhaust pollution. In July of this year, Shijiazhuang City purchased 411 natural gas air-conditioned buses and its brand was the Yellow Sea passenger vehicle. Its emissions all reached the fifth level. During this critical transition, natural gas buses became the absolute “protagonist†of Shijiazhuang public transport and diesel. Compared with vehicles, the major pollutants discharged from natural gas emissions can be reduced by 98%.
The reporter also learned that Shijiazhuang Public Transport Co., Ltd. loves natural gas, and in addition to its green features, it also tasted the sweetness of natural gas in operating costs. It is reported that in the bus company's operating costs, the vehicle's fuel cost is one of the major expenditure items. The 12-meter diesel fuel is used as the bus. The fuel consumption per 100 kilometers is generally more than 30 liters. Bus companies that are under tremendous pressure to withstand the pressure are overwhelmed. After a rough calculation, the fuel cost of natural gas buses accounts for only 23% to 24% of the total cost. Compared with diesel vehicles, it is not only energy-saving and environmentally friendly, but also economically efficient.
It is understood that since the country has proposed “energy saving and emission reductionâ€, new energy buses and clean energy buses have become the symbol of “energy saving and emission reduction†and “green travel†throughout the country, and after years of exploration and practice, China’s natural gas vehicles and new Energy automotive technology is more mature than technology, and its market should be more extensive. In 2013, the introduction of the national new energy subsidy policy, the reduction in the amount of subsidy, to a certain extent, affected the speed of the popularization of new energy vehicles, which means that clean energy is likely to become the preferred product for smog control everywhere.
