·Easy to commercialize the application of Chinese and foreign natural gas commercial vehicles

Natural gas heavy trucks are easy to commercialize and popularize at the forum. Liang Hao, deputy director of technical quality department of Chengdu Yunnei Power Co., Ltd., said that he is very optimistic about the development prospects of liquefied natural gas (LNG) in the commercial vehicle field. He believes that China's natural gas resources are abundant. If conventional and unconventional (hydrates) are used as resources, it can be used for at least two or three hundred years.
"In the past two years, the country has been paying more and more attention to the development of natural gas. Several large orders recently signed with foreign countries are related to natural gas, which also shows the government's emphasis on natural gas applications," Liang said.
However, at the national policy level, Liu Guibin, secretary general of the National Automotive Standardization Technical Committee Gas Vehicle Sub-Technical Committee, said that the State Council has recently introduced new energy vehicle policies, while the policies on natural gas vehicle applications are not many. “The country has been paying close attention to pure electric power as a breakthrough that is likely to catch up with Western developed countries. This is a demand at the national strategic level.”
According to Liu Guibin, in fact, China's current pure electric vehicles have been at a loss. “Looking at natural gas vehicles, enterprises and users are profitable in the absence of much support from national policies. In the field of commercial vehicles, Shaanxi Automobile Group now has a market share of 20,000 or 30,000 LNG heavy trucks. The rapid development of LNG heavy trucks shows that the market segment can be driven by demand and the outlook is optimistic."
As a representative of the production company, Sun Xia, director of the New Energy Institute of the Power Design Institute of China National Heavy Duty Truck Group Co., Ltd., explained the advantages of natural gas heavy trucks. She said that heavy trucks accounted for less than 10% of the auto market share, but fuel consumption accounted for 70% of the total. Therefore, the development of natural gas heavy trucks has a certain effect on the adjustment of China's energy structure.
“In addition, the development of natural gas heavy trucks will help reduce the operating costs of transportation companies. According to the National Energy Administration’s long-term price adjustment plan, natural gas prices are 70% of gasoline and diesel prices, and the price advantage is obvious. At present, natural gas heavy truck technology is very mature (including engines). Technology) is the most easily promoted and popularized technology in the world.” Sun Xia believes that natural gas vehicles are superior to pure electric vehicles in terms of economy and resources.
LNG applications in the transportation sector in developed countries At the forum, Brenda Smith, vice president of the International Gas Vehicle Association, introduced the development of LNG applications in other countries' transportation sectors.
“China has been ahead of many countries in natural gas vehicle applications. In other parts of the world, LNG is also one of the main fuels, but it is just beginning to apply LNG in the transportation industry, and it is also developing rapidly.” According to Brenda Smith, “USA Advocating the use of LNG in the commercial vehicle sector, many projects are also being promoted, but the quantity is not as good as China; the non-road growth is faster, some sea transportation in New York has begun to use LNG, and the demand for marine transportation is very large. The oil transportation industry has started to use LNG, and the mining industry will start later. It will be used in 2015 or 2016. At present, some natural gas production plants and liquefaction plants in the United States have been set up specifically for the transportation industry. The United States can become the second largest country in LNG transportation applications."
In Europe, many countries such as Spain, the United Kingdom and the Netherlands also use LNG in the transportation sector. “Since 1997, the UK has used LNG as a fuel in the public transport sector, but it has only grown in the past few years. The UK has a very good filling station system that can refuel anywhere. Their The filling station is very unique and very simple. It does not use any pumps and is mainly filled with gravity. Moreover, these filling stations can be moved or sent to many places and can be loaded in one day. However, (gas filling) The efficiency is not too high, but it is very good in many aspects such as cost control, and the whole market is using this convenient refueling method," Brenda Smith said.
She also mentioned Belgium, “The LNG production there is very high, with an annual output of about 210,000 cubic meters. It can also see a significant increase in demand. There are currently three major large LNG filling stations with 26 LNG plus. Gas trucks can be opened to the public at any time."
In addition, Brenda Smith believes that Australia's LNG market is also developing very well, and many projects and plans are underway; Australia is the world's leading country in LNG production technology.
Later, Brenda Smith also introduced foreign new technologies for natural gas production and applications. “One is V-type LNG production, which can be produced on demand without the need to store large amounts of LNG in advance, which means that evaporation loss can be reduced. Moreover, using biogas to produce LNG, landfill gas or Exhaust gas production, which can be used as a feedstock for natural gas liquefaction plants. Another technology is mobile gas station technology. In more remote areas, there is not enough demand, and mobile stations need to be supplied with gas."
