The use of gas buses in China mainly focuses on the neighboring provinces and cities of the three major gas-producing regions in the central and western regions where gas resources were developed earlier and where reserves are abundant, as well as developed economic regions where gas transportation is well-developed.
As of the end of 2004, the country has identified 16 cities (regions) in Beijing, Shanghai, Chongqing, Tianjin, Sichuan, Hainan, Harbin, Changchun, Xi’an, Urumqi, Guangzhou, Yinchuan, Jinan, Qingdao, Langfang and Xiangyang as the focus of clean vehicles. The promotion of cities (regions) can be broadly divided into: Sichuan-Chongqing region, northeastern region, Yangtze River Delta region, Beijing-Tianjin region, Central Plains region, Guangzhou-Shenzhen region, and Hainan region.
As of the end of 2004, there were approximately 40,000 gas buses in China. The use of gas buses in 16 urban areas is described below.
Beijing: The alternative fuel buses for promotion and application mainly include: compressed natural gas (CNG) buses, liquefied petroleum gas buses (LPG), and liquefied natural gas buses (LNG). Among them, CNG passenger cars and LPG passenger cars have already begun to use and are in the stage of industrialization; LNG passenger cars are still in the demonstration operation stage.
By the end of 2004, Beijing had 2,089 CNG buses (mostly Cummins CNG engines, all produced by vehicle manufacturers, of which 800 diesel-fueled CNG vehicles), and 1712 LPG buses (including diesel LPG vehicles There are 69 LPG refueling stations, 27 CNG refueling stations and 1 LNG refueling station. Beijing has become the city with the largest number of CNG buses in the world. The buses used are mostly produced by Beijing Jinghua Bus Factory.
Beijing plans to use CNG and LPG fuels for 90% of buses operating in urban areas by 2008.
Shanghai: LPG applications are mainly in taxis, and gas buses are mainly CNG vehicles. As of the end of 2004, the city maintained about 175 CNG buses, including 70 single-fuel vehicles and 4 CNG refueling stations. Passenger buses used are Shanghai Shenwo products.
In April of this year, relevant parties in Shanghai held a comprehensive advancement of the “CNG†mobilization meeting. It is planned that by 2007, about 3,000 diesel buses will be converted into CNG vehicles. Change the status quo of only four CNG refueling stations and 175 CNG buses in Shanghai.
Tianjin: As of the end of 2004, the number of CNG vehicles in Tianjin reached 850, and the number of LPG vehicles reached 760, of which taxis were mostly; 12 LPG refueling stations for vehicles and CNG refueling stations have been built. By the end of the year, 40 single-fuel CNG buses produced by the Tianjin Bus Assembly Plant will be put into the Tianjin market.
Chongqing: It is one of the main producing areas for natural gas in China. Its alternative fuel buses are mainly CNG vehicles. As of 2004, 7,369 CNG passenger cars were built in Chongqing, and a total of 46 CNG filling stations were built. Most of the vehicles are produced by Chongqing Yutong.
Sichuan Province: With abundant natural gas resources, the accumulated proven reserves are approximately 818.3 billion m3, the recoverable volume is approximately 480.8 billion m3, and the annual output of natural gas exceeds 10 billion m3, ranking first in the country. The average selling price of CNG in Sichuan is maintained at 1.6~1.8 yuan/m3.
Sichuan Province has natural gas, methanol, ethanol, biodiesel and other alternative fuel buses, but it is mainly based on natural gas. By the end of 2004, there were 7995 natural gas buses, accounting for 20% of the total natural gas vehicles in Sichuan Province. There are 185 CNG filling stations. The products are mainly manufactured by Chongqing Yutong, and Beiqi Foton and Xiamen Golden Dragon products have also entered this market this year.
Hainan Province: Gas buses in Hainan Province are mainly CNG. By the end of 2004, seven CNG refueling stations for vehicles and 235 CNG buses were completed.
Urumqi: Xinjiang's Tarim Basin has abundant natural gas resources. By the end of 2004, Urumqi City had 2362 CNG buses, 770 LPG buses, and gas buses accounted for 65% of the total number of buses. Thirty-four LPG refueling stations and 30 CNG refueling stations have been built.
Changchun: LPG buses are the mainstay for gas buses. By the year 2004, about 1761 buses were LPG buses, accounting for 60.6% of the total number of buses. It has 36 LPG refueling stations and 2 CNG refueling stations. Dandong Yellow Sea products are mostly.
The sales price of LPG in Changchun is 2.6 yuan/L, and CNG sold price is 2.4 yuan/m3. The average monthly sales volume of LPG is about 4100 tons, and CNG's average monthly gas sales volume is 600,000 m3.
Xi'an: Gas buses are mainly CNG vehicles. As of 2004, there were 1,476 gasoline/natural gas dual-use fuel buses, accounting for 23.3% of the total number of buses. CNG filling stations have been built and operated. Mainly the improvement of the original model.
Guangzhou: Gas buses are mainly LPG vehicles. As of 2004, the number of LPG city buses in the city is about 4010, which is more than half of the total number of local buses. At present, Guangzhou LPG single-fuel city bus is the first in the world in terms of quantity. It was built using 14 LPG filling stations. The majority of products are Guangzhou Denway buses.
At present, relevant departments in Guangzhou have conducted research on the development of LNG buses and other aspects; the LNG city buses of the Guangzhou Denway Bus Factory will soon produce prototypes. Industry insiders estimate that with about 20,000 buses in Guangdong, the promotion of the use of natural gas buses will start a large market of over 10 billion yuan.
Harbin: Alternative fuel vehicles mainly include LPG vehicles and methanol trucks. As of 2004, there were 2209 LPG buses and more than 40 M30 methanol gasoline buses. Twenty-seven gas filling stations have been built, of which 90% are oil and gas mixing stations and are distributed in 8 districts of the city. Each district has 3 to 4 gas stations.

Langfang: As of the end of 2004, Langfang City has developed CNG and 260 buses; 5 gas stations have been built.
The gas supply system for gas in Langfang was initially formed. Langfang City is located in the important oil and gas production area of ​​Huabei Oilfield, with an area of ​​more than 400,000 m2 of natural gas. The gas supply capacity of Huabei Oilfield to Langfang City is 380,000 m3/day.
Xiangyang: As of the end of 2004, Fuyang City had cumulatively developed 425 CNG buses; 8 CNG refueling stations have been built, covering a wide area of ​​the city and the suburbs, with a total refueling capacity of 90,000 m3/day.
