The smooth holding of the Winter Olympic Games and the Winter Paralympic Games has also brought Zhangjiakou's hydrogen energy industry development map into the public eye.
Recently, Bai Yan, chairman of Zhangjiakou Jiaotong New Energy Company, pointed out to the media that the Winter Olympics is the largest commercial vehicle applied to hydrogen fuel in the history of the Olympic Games, and the number of operations previously in the Tokyo Summer Olympics held in 2021 was more than 200.
It is understood that during the Winter Olympics, a total of 710 hydrogen fuel cell vehicles were put into use in Zhangjiakou Racing District, including 623 in Chongli District and 87 in the main urban area. Together with the operating vehicles in beijing, the cumulative number exceeds 1,000.
In fact, as early as 2016, Zhangjiakou launched the hydrogen energy industry layout. Since 2018, the city has put into operation a total of 444 hydrogen fuel cell buses, with a cumulative passenger capacity of more than 62 million passengers and a cumulative operation of more than 21 million kilometers, making it one of the cities with the largest number and most stable fuel cell vehicles in the country.
"I hope that this Winter Olympics can be used as an opportunity to open the curtain on the commercial demonstration operation of hydrogen fuel cell vehicles." This successful service to the Olympic Games has also given the industry greater confidence. On February 19, Yin Xuguang, director of the high-tech division of the Zhangjiakou Development and Reform Commission, said so.
The "low temperature test" of the Winter Olympic Games successfully passed the Olympic Organizing Committee because of concerns about "many field visits"
Although Zhangjiakou has accumulated many years of operational experience before the Winter Olympics, from the government to the Olympic Organizing Committee, it has come here many times to investigate the field because of concerns about technology and stability.
It is worth mentioning that the development of new energy vehicles with lithium-ion batteries as the mainstream for many years is still unable to solve the problem of declining endurance in winter, although the performance of hydrogen fuel cell vehicles performs well at low temperatures, but in the past there was also the problem of "low temperature start difficulty".
At the same time, although Zhangjiakou is only 100 kilometers north of Beijing, the geographical environment such as low temperature, strong wind and large terrain slope is also a big test for hydrogen fuel cell vehicles.
It is understood that the power system and stack of hydrogen energy buses currently operating in the urban area are provided by Yihuatong and Shenli respectively. Yu Min, executive deputy general manager of Beijing Yihuatong Technology Co., Ltd., told Tencent Automobile that the bus of hydrogen fuel cells released in Zhangjiakou has a special feature, that is, the engine is equipped with integrated thermal energy management technology, which can convert the excess heat energy during engine operation into heating energy in the passenger compartment, and there is no need to open the air conditioner at minus 30 degrees.
"In this way, there is no need to consume hydrogen in winter for heating, and in theory, hydrogen fuel cell vehicles will have more endurance in winter than in summer." He pointed out.
Kingston is the more upstream company of Yihuatong, mainly doing air compressors, and Wang Qingfeng, deputy general manager of its fuel cell division, stressed, "In the past, customers who undertook only required a low temperature environment of minus 20 degrees, but when they arrived in Zhangjiakou, they needed minus 30 degrees, so we had to do targeted development." ”
The person in charge of the bus hub station told Tencent Automobile that the hydrogen fuel buses currently running in the city have good performance, the product has been upgraded to the third generation, the daily endurance can reach 400km, the low temperature preheating time takes only 5 minutes, and hydrogen can be added once a day, mainly in two fixed hydrogen refueling stations. At the same time, the government has also implemented preferential electricity price policies, and the cost of use is calculated, which is "equivalent to the cost of fuel vehicles".
The whole industrial chain layout hydrogen energy government specially approved the "first to try" policy
The hydrogen production methods used here are all green energy, that is, "green hydrogen", which can achieve zero emissions, but the cost is also higher.
To this end, Zhangjiakou also strives to enjoy the preferential policies of "spontaneous self-use and surplus internet access" for wind power hydrogen production in the six months before and after the Winter Olympics, and to cancel the preferential policies of capacity electricity charges in the two-part electricity price.
At present, Zhangjiakou has built 4 hydrogen plants such as Haiper, Jiaotou Shell, Hebei Jiantou Guyuan, Hebei Jiantou Chongli, etc., with a total hydrogen production capacity of 17 tons / day.
It is worth mentioning that the Zhangjiakou government also applied for a special approval of the "first to try" policy in the construction of hydrogen plants, which makes it more convenient to build hydrogen plants around the wind farm. In the past, hydrogen was classified as a hazardous chemical, and hydrogen plants could only be built in chemical parks.
Since the early stage, Zhangjiakou has adhered to the layout of the whole industrial chain, and the agglomeration effect of industrial development has gradually emerged. It has cultivated and introduced 18 hydrogen energy industry chain enterprises such as Yihuatong, Haiper and Xiamen Jinlong.
Specifically, the second phase of Yihuatong's annual output of 10,000 fuel cell engine projects have been completed, hydrogen energy technology annual output of 4,000 sets of air-cooled hydrogen fuel cell stack production lines and other projects are steadily advancing, Jutong Technology 150MW fuel cell stack project and test workshop and other projects have been built; Beiqi Foton Ouhui hydrogen energy bus project has been put into production, Zhangjiakou Yilong intelligent hydrogen energy commercial vehicle industry base project and Hydrogen Automobile and other vehicle manufacturing projects are also advancing in an orderly manner.
Significant reduction in vehicle and station construction costs "100% autonomy rate will certainly be achieved within 5 years"
After years of development, the hydrogen energy industry has gradually improved its technical stability, and its costs have also declined rapidly.
An industry insider revealed to Tencent Automobile that we had previously purchased 3 Fuel cell buses from German Mercedes-Benz in 2006 to serve the 2008 Olympic Games, and the purchase price of 1 car was 1.8 million US dollars, and now the same model is enough to buy 1.8 million yuan. "At that time, the car was not mature, there was no technology for low temperature start, and we built a huge greenhouse for this car to start."
Yu Min said that the localization rate of many parts and components is very high, and only a small number of core components still need to be imported. "There are also many foreign companies to build factories in China, but their pace is still slow, domestic air compressors, hydrogen cylinders have a good domestic alternative enterprises, it is expected that within 5 years will certainly be able to achieve 100% autonomy rate."
The increase in the localization rate of parts and components is obvious to the cost reduction. "In 2018, we bought an air compressor at a cost of 180,000-200,000 yuan, and now the domestic stamping press is now 20,000 yuan, and other parts are also in this situation." He pointed out.
According to Yu Min, the manufacturing and production costs of hydrogen fuel cell vehicles in the mainland are decreasing at a rate of 25% per year.
At the same time, Bai Yan revealed that the cost of civil engineering and equipment for the construction of hydrogen refueling stations has also dropped by nearly half compared with 2018. "At present, the annual equipment cost is about 20% reduced, and the government is also encouraging enterprises to invest in construction and commercial operation.
In order to respond to the market more flexibly, Zhangjiakou is also carrying out demonstrations of hydrogenation-refueling, hydrogenation-refueling, hydrogenation-charging and other joint construction stations, and promoting the construction of hydrogen production, hydrogen storage and hydrogenation integrated hydrogen refueling station projects in the station.
At present, the Wanquan Oil Hydrogen Station adjacent to the bus station of Zhangjiakou High-tech Industrial Development Zone is a comprehensive smart energy station integrating oil and hydrogen electricity. According to the "Technical Standard for Automobile Refueling and Refueling Hydrogen Refueling Station" (GB50156-2021), the total storage volume of diesel and gasoline is 120m, providing 0# diesel, 92# gasoline, 95# gasoline; The total hydrogen storage capacity is 960kg, 35MPa daily hydrogen refueling capacity is 1000kg, and there is a 70MPa mobile hydrogen refueling station with a daily refueling capacity of 200kg to provide 70MPa hydrogen refueling services; equipped with 5 fast charging piles to provide electric vehicle charging services.
Urban demonstration application landing hydrogen energy industry development into the next "outlet"
In December last year, the implementation plan of the fuel cell vehicle demonstration application city cluster in Hebei Province led by Zhangjiakou City was approved by the Ministry of Finance and other five departments.
It is understood that the urban agglomeration of Hebei Province is composed of a total of 14 cities with 1 +8+N, of which "1" indicates the lead city of Zhangjiakou, "8" indicates 7 cities in Hebei Province and Wuhai City in Inner Mongolia, including Tangshan City, Baoding City, Handan City, Qinhuangdao City, Dingzhou City, Xinji City, and Xiong'an New District. "N" indicates cities that strengthen the industrial chain of urban agglomerations but do not participate in the task of vehicle promotion, such as Fengxian District of Shanghai, Zhengzhou City of Henan Province, Zibo City of Shandong Province, Liaocheng City of Shandong Province, and Xiamen City of Fujian Province.
According to the implementation plan of Hebei Group, during the 4-year demonstration period, the hydrogen production capacity of Hebei Urban Agglomeration reached 200,000 tons, of which green hydrogen accounted for more than 60%, and the technology breakthrough and industrialization of 8 core components of fuel cell stacks, air compressors, membrane electrodes, bipolar plates, catalysts, proton exchange membranes, hydrogen circulation systems, and carbon paper technology were realized, and large-scale demonstration applications were realized; 7710 fuel cell vehicles of various types were cumulatively promoted and applied, including 1680 fuel cell buses and 5980 fuel cell trucks (1370 logistics vehicles, There are 4320 heavy trucks, 290 special vehicles, 50 fuel cell passenger cars, and 86 hydrogen refueling stations.
Among them, Zhangjiakou City will produce more than 50,000 tons of hydrogen during the "14th Five-Year Plan" period; through policy support, technological upgrading and other measures, the cost of renewable energy electrolyzed water hydrogen production will strive to be reduced from 30 yuan / kg to 14 yuan / kg; 14 hydrogen refueling stations will be built; and 1130 fuel cell buses, commuter buses, logistics vehicles, heavy trucks, and sanitation vehicles will be promoted.
