Recently, the reporter interviewed in Beijing, Tianjin, Wuhan, Hohhot, and other places found that with the maturity of natural gas use technology, natural gas powered vehicles with environmental protection and conservation effects have been welcomed by some private car owners and manufacturers. However, natural gas vehicles are also experiencing market bottlenecks. The main reason why some vehicle owners are not willing to refit or purchase is because the number of refueling stations is small, and refueling is very inconvenient.
Insiders pointed out that in the short term, it is difficult to build new gas stations and refit gas stations. In the long term, the demand for natural gas has increased rapidly, and the tight supply situation has existed for a long time.
Aerating line
The staff of the Huhhot Huihengli Natural Gas Automotive Refitting Plant told the reporter that although “oil-to-gas†can significantly reduce costs, some manufacturers have also introduced dual-use vehicles, but consumer interest has decreased in the recent period. Because of the small number of filling stations, it is inconvenient to add air.
A few days ago, the reporter saw the first terminal station of compressed natural gas in Tianjin's Xiqing District. At least five or six hundred meters were waiting for the refueling team. Mr. Fang, a taxi driver who was standing in line, told reporters: “Summer has to wait two or three hours, and winter one or two hours.†Another driver, Luo, said: “Every day we must add one gas, one row at a time. Hours of the team, the business has been delayed." Reporter survey found that this situation occurs frequently in Wuhan, Beijing, Hohhot and other places.
“We operate four large gas stations in Tianjin city, which still falls short of supply.†Fan Yuxiang, General Manager of Tianjin CNG Vehicle Fuel Technology Co., Ltd. introduced that it is still very difficult for four gas stations to continue filling at full capacity for 24 hours. Meet the refueling needs of the vehicle. The second terminal is designed to add 100,000 cubic meters of air per day, and it is now added to 200,000 cubic meters per day and is seriously overloaded.
FAN Yuxiang told reporters that he had always hoped to build more gas filling stations in the central city. However, according to the regulations, he must choose commercial land but also away from residential areas and find almost no suitable land.
The existing filling stations in Beijing are basically outside the Fourth Ring and the Fifth Ring, and the number is very limited. The reporter learned that even when the Beijing refueling station reached its peak of nearly 90 seats in 2001, the number of refueling stations was still relatively small compared with the demand. Refueling has always been a difficult problem for drivers. But now, there are few refueling stations in Beijing's urban areas, and refueling has become an obstacle to the promotion of natural gas vehicles.
It is difficult to build a gas and oil mixing station
As the difficulty of building new gas stations is relatively large, some experts suggest that gas stations that are widely spread over and over are being upgraded, natural gas pipeline networks will be introduced, and gas filling functions will be realized. However, the reporter found that due to the involvement of multiple competent authorities, the implementation of this method is relatively difficult.
Beijing's gas sector stated that it is relatively simple to increase natural gas equipment by adding a set of pressurized gas transmission equipment. At present, gas pipeline networks in Beijing are all over the city. Gas stations can be gas-fired nearby without adding large-scale gas storage equipment. Simply carrying out pipe laying and connecting with a nearby gas pipeline network can introduce gas into gas stations.
But when the reporter interviewed a gas station in Beijing's West Third Ring Road, the staff told reporters that the space at the gas station was very tense. If the gasification facilities were to be increased, the biggest difficulty was the space for the installation of gas storage equipment. The current tanker is only four to six, and the space has become very narrow.
In addition, even new oil and gas mixing stations face many difficulties. A staff member of Zhongchuan City Gas Development Co., Ltd. in Huhhot City, who said on condition of anonymity, said that “it is not easy to build oil and gas mixing stations because there are many departments involved and coordination and approval procedures are complex. For example, a review of safety design is required. In order to analyze the environmental impact, we must also make arrangements according to the city's road planning, with as many as a dozen departments involved."
Ma Hui, Operations Manager of Wuhan Jiangyan Natural Gas Company, said that the difficulty in building a new oil and gas mixing station lies in the shortage of land resources. The oil and gas mixing station in the main urban area covers an area of ​​2,000 square meters. Most of the suitable land is used for real estate development. The area is too small to be constructed.
The contradiction between supply and demand persists
In recent years, there have been many natural gas shortages in some cities in China, which have affected both the daily lives of residents and the intensification of natural gas vehicles.
First, there is a strong demand for natural gas and high external dependence. The “12th Five-Year Plan for Natural Gas Development†shows that during the “12th Five-Year Plan†period, it is estimated that China’s annual average new natural gas consumption will exceed 20 billion cubic meters, and China’s dependence on natural gas will continue to increase. The issue of gas supply safety needs high attention. In 2010, China’s dependence on natural gas has exceeded 15%, and it is expected to exceed 35% in 2015.
Huang Zejun, a senior expert in the industry and general manager of West-East Gas Pipeline, said that with the adjustment of China's energy structure and further economic development, the rapid increase in the demand for natural gas will become a long-term trend, and supply shortages cannot be fundamentally alleviated.
Second, the rapid growth in transportation demand has partially aggravated the contradiction between supply and demand. In 2009, there was a large-scale supply of gas in Wuhan, and the taxi’s “oil to gas†progress was too fast. Therefore, filling stations had to suspend taxi refueling for 10 days. All taxis temporarily refueled. The government Each vehicle compensates 100 yuan for fuel.
Third, the lag in infrastructure construction has affected the effective delivery of natural gas.
The 12th Five-Year Plan for Natural Gas Development pointed out that the lag in infrastructure construction has become a bottleneck restricting the application of natural gas in China. For a long time, China's natural gas pipeline network system is not yet complete, and some areas have not yet been covered. The regional transmission and distribution network is underdeveloped, especially the capacity building of gas storage is seriously lagging behind. At present, the gas storage capacity of the gas storage only accounts for 1.7% of the consumption. Far below the world average of 12%.
