In the past two years, as natural gas vehicles have been favored by the market and users, various related forums and summits have been held one after another. This shows that the application of natural gas in the transportation field has made more and more people realize that natural gas The development of clean energy is promising.
Not long ago, at the "2014 Second China Natural Gas Automobile Industry Forum" held in Beijing, many domestic and foreign experts expressed their opinions and views on the application and prospects of natural gas in the commercial vehicle sector, drawing attention from many media. .

Shaanxi Steam LNG heavy truck
Natural gas heavy trucks are easy to commercialize and popularize
At the forum, Liang Wei, Deputy Minister of Technical Quality of Chengdu Yunnei Power Co., Ltd. expressed great interest in the prospects for the development of liquefied natural gas (LNG) in the commercial vehicle sector. He believes that China's natural gas resources are abundant. If conventional and unconventional (hydrates) are used as resources, they 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 big orders signed recently with foreign countries are all related to natural gas, and it also shows that the government attaches great importance to the application of natural gas,†Liang said.

However, at the national policy level, Liu Guibin, secretary general of the Gas Vehicle Sub-Technical Committee of the National Automotive Standardization Technical Committee, said that the State Council has recently introduced new energy automobile policies, and there are few policies on the application of natural gas vehicles. “The state has been paying close attention to pure electric power as a breakthrough that is likely to catch up with Western developed countries. This is at the national strategic level.â€
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 even if there is not much support from national policies. In the commercial vehicle sector, Shaanxi Automobile Group now has a market holding of 20,000 to 30,000 LNG heavy trucks. The rapid development of LNG heavy trucks shows that this market segment can be fully driven by demand and the outlook is optimistic."
As a representative of a production company, Sun Xia, director of the New Energy Institute of the Power Design Institute of China National Heavy Duty Truck Group Technology Development Center, explained the advantages of natural gas heavy trucks. She said that heavy trucks account for less than 10% of the vehicle market, but fuel consumption accounts for 70% of the total. Therefore, the development of natural gas heavy trucks has a certain role in adjusting China's energy structure.
"Moreover, the development of natural gas heavy trucks will help reduce the operating costs of transportation companies. According to the long-term price adjustment plan of the National Energy Administration, natural gas prices are 70% of the prices of gasoline and diesel, and the price advantage is obvious. At present, natural gas heavy truck technology is already 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 transport industry in developed countries
At the forum, Brenda Smith, Vice President of the International Natural Gas Vehicle Association, introduced the development of LNG applications in the transportation sector in other countries.
“China has already led many countries in the application of natural gas vehicles. In other parts of the world, LNG is also one of the main fuels, but all of them are just beginning to use LNG in the transportation industry and the development is also faster.†According to BrendaSmith, “The United States is Advocates the use of LNG in the field of commercial vehicles. Many projects are also being promoted, but the amount is still not as good as China. The growth in non-road areas is relatively fast. New York has some marine transportation that has begun to use LNG, and the demand for marine transportation is very promising. The oil transportation industry has begun to use LNG. The mining industry will be a little later, and will start to use it in 2015 or 2016. At present, there are some natural gas production plants and liquefaction plants in the United States that are set up specifically for the transportation industry. It will become the second largest country in LNG transportation applications."
British Gas Refueling Station
In Europe, many countries such as Spain, the United Kingdom, and the Netherlands also use LNG in the transportation sector. “Since 1997, the United Kingdom has used LNG as a fuel in public transport, but only in the past few years has been a long-term development. Britain has a very good refueling station system that can refuel anywhere. Their Refueling stations are very unique and very simple, do not use any pumps, and are mainly used for refueling with gravity, and these refueling stations can be moved or sent to many places and can be loaded in one day. The efficiency is not very high, but it is very good in many aspects such as cost control, and the entire market is using this convenient way of refueling,†said BrendaSmith.
She also mentioned Belgium. "The production of LNG there is very high. There are about 210,000 cubic meters of production each year. We can also see a substantial increase in demand. At present, there are three major large-scale LNG refueling stations in the region, with 26 LNGs added. Air trucks can be open to the public at any time."
US LNG Refueling Station
In addition, BrendaSmith 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 terms of LNG production technology.
After that, BrendaSmith also introduced foreign new technologies on natural gas production and application. "First, V-type LNG production, this technology can be produced according to demand, without the need to store large amounts of LNG in advance, which also means that it can reduce the loss of evaporation. Moreover, LNG can be produced using biogas, you can use landfill gas or Exhaust gas production, which can be used as raw materials for natural gas liquefaction plants. Another technology is the mobile gas station technology. In relatively remote areas, there is not enough demand, you need to move the gas station to provide gas for vehicles."
