How hydrogen fuel cell vehicles can guarantee the Green Winter Olympics

Beijing is the first "double Olympic city" to host the Summer Olympic Games and the Winter Olympic Games, and the two Olympic Games have also formed a deep "hydrogen" relationship with hydrogen fuel cell vehicles. During the 2008 Beijing Summer Olympics, the mainland built the first hydrogen refueling station for vehicles, opening a demonstration of hydrogen fuel cell vehicles "from 0 to 1"; by the 2022 Beijing Winter Olympics, hydrogen fuel cell vehicles have become the main force of transportation.

In order to ensure the transportation of events during the Winter Olympic Games, from the use of models to the production, transportation and supply of hydrogen, behind each link is the support provided by various enterprises. The low emissions and low temperature resistance of hydrogen fuel cell vehicles have become a bright green during the Winter Olympics, showing the world that the Winter Olympics have always adhered to the concept of low carbon and sustainability.

"The Ultimate Eco-Car"

The Olympic athletes in the Winter Olympic Games are competing in full swing, the support work under the field is also advancing in an orderly manner, and the transportation field is the "main play". In the three major competition areas, shuttle transport vehicles transport athletes to the arena safely and with peace of mind every day to ensure the smooth progress of the Winter Olympic Games.

The main force of transportation at the Winter Olympics is the hydrogen fuel cell vehicle that was unveiled at the 2008 Olympic Games. Wu Zhiquan, deputy director of the Automobile Transportation Department of the Beijing Municipal Bureau of Economy and Information Technology, said that a total of 816 hydrogen fuel cell vehicles were put into use at the Beijing Winter Olympics as the main transport capacity to carry out demonstration operation services, which is the largest investment in major international events so far. Among them, the number of buses set a record for the largest number of international sports events in the history of hydrogen fuel cell large buses serving.

The Beijing Winter Olympics adhere to the concept of green, shared, open and clean, while hydrogen fuel cell vehicles only discharge water during the driving process, so they are called "the ultimate environmental protection vehicles", which is the reason why hydrogen fuel cell vehicles have become the main traffic force of the Winter Olympics. At the same time, hydrogen fuel cell vehicles can achieve -30 °C low temperature start, -40 °C low temperature storage and automatic protection of shutdown, and the mileage of the bus can reach more than 400 kilometers. This means that hydrogen fuel cell vehicles have the characteristics of low temperature resistance and long endurance, and can effectively guarantee the transportation work during the Winter Olympics.

The problem of how to ensure the temperature of the athletes in the carriage during the ride at low temperatures is also a concern before the vehicle is released. Liu Jihong, vice president of R&D of Foton Auto Ouhui Bus Division, said: "We have developed a 'U degree' integrated thermal management technology, which can recycle the waste heat generated by hydrogen fuel cells, use the waste heat generated for interior heating and front windshield defrosting and fogging, and achieve full waste heat heating when the fuel cell power reaches 75%, and reduce the energy consumption of the vehicle by 7.6%. ”

Hydrogen is transported 24 hours a day

It is understood that a total of 312 hydrogen fuel cell vehicles have been invested in the two competition areas in Beijing, and about 42.04 tons of hydrogen have been used since the opening of the Winter Olympics on February 4 to February 14. In the process of hydrogen fuel cell vehicles, how to ensure the production, transportation and supply of hydrogen energy has also attracted much attention.

As a hydrogen source supply guarantee unit for hydrogen fuel cell vehicles in the Winter Olympics of Science and Technology, Huanyu Jinghui cooperates with Jingneng Group to use the "green electricity" generated by photovoltaics and wind energy to produce hydrogen and realize "green electricity to green hydrogen". "We are guaranteeing the hydrogen production, storage and transportation links of the Winter Olympics, manufacturing 500 cubic meters per hour and supplying 1.5 tons per day to the Winter Olympics." Zhang Yan, deputy general manager of Huanyu Jinghui Jingcheng Gas Technology Co., Ltd., said that in order to ensure the hydrogen demand for the Winter Olympics, the hydrogen filled every day will be placed in the hydrogen storage area, and after the hydrogen refueling station is contacted, Huanyu Jinghui will be transported to the past, transported throughout the day at any time, and the tank filled with hydrogen will be installed after the hydrogen refueling station, and then the empty jar will be pulled back.

Since hydrogen itself is a flammable gas, how to ensure safe transportation is crucial. Zhang Yan told the Beijing Business Daily reporter: "In our command center, there is a monitoring system, including vehicle location scheduling, etc., and there are potential safety hazards that will communicate with the driver at any time to avoid accidents and ensure the safe and efficient distribution of hydrogen energy during the Winter Olympics." ”

At the same time as the hydrogen source production end and the supply end are guaranteed, the fuel cell engine is also one of the stable operation guarantees of the vehicle. During the Winter Olympics, there were 569 fuel cell vehicles equipped with Yihuatong engines in the closed loop. Yu Min, executive deputy general manager of Beijing Yihuatong Technology Co., Ltd., told Beijing Business Daily reporter: "In order to adapt to the ultra-low temperature environment in the Winter Olympic Games, Yihuatong and Foton Ouhui Bus completed the extreme cold test in Hailar in January 2020. In August last year, we set up the Winter Olympics Service Guarantee Working Group, and during the official competition, the service guarantee team provided service support work for the Winter Olympic traffic vehicles in Yanqing, Chongli and the main beijing areas, and regularly inspected, inspected and maintained the vehicles to ensure that the vehicles had a good operating state. ”

Beijing's "Green Business Card"

Effectively ensure that hydrogen fuel cell vehicles are put into use, so that the background color of "green" for the Beijing Winter Olympics is more bright.

It is understood that hydrogen fuel cell vehicles during the Winter Olympics achieved zero carbon emissions in transportation activities. According to the data, Toyota Mirai passenger cars can reduce carbon dioxide emissions by about 18.79 kg per 100 kilometers, Toyota Costa minibuses can reduce carbon dioxide emissions by about 47.01 kg per 100 kilometers, and Toyota-Foton's 12-meter bus can reduce carbon dioxide emissions by about 57.86 kg per 100 kilometers.

It is worth noting that the Beijing Winter Olympics have also promoted the revision of the industry standards for hydrogen energy and hydrogen fuel cell vehicles. Wu Zhiquan said that in order to realize the use of hydrogen fuel cell vehicles in the Winter Olympics, promote the revision of standards such as "Fuel Cell Electric Vehicle HydrogenAtion Port", "Fuel Cell Electric Vehicle Vehicle On-board Hydrogen System Test Method" and "Fuel Cell Electric Vehicle Vehicle On-board Hydrogen System Technical Conditions".

Not only that, the Beijing Winter Olympics have promoted the improvement of the hydrogen refueling station construction process. In fact, hydrogen refueling stations are a new thing, the safety level requirements are high, and the relevant technology is still in the stage of continuous development and improvement. Wu Zhiquan told the Beijing Business Daily reporter that in order to ensure the safe and stable operation of the hydrogen refueling station, the approval process of the oil-hydrogen joint construction station was clarified, and the working procedures and working methods were innovated to ensure that the four hydrogen refueling stations serving the Winter Olympics, Qingyuan Street, Wang Quanying, Jinlong and Yanhua Xinglong, were legally put into operation, accumulating rich experience for the construction of hydrogen refueling stations in the future.

At the same time, the Beijing Winter Olympics promoted the establishment of a hydrogen energy safety guarantee mechanism. It is understood that the competent departments in all aspects of hydrogen energy have coordinated the establishment of safety guarantee measures and working mechanisms for the whole industrial chain of hydrogen energy production, storage, transportation, addition and use, which ensures the safe operation of hydrogen fuel cell vehicles during the Winter Olympics, and also provides organizational guarantees for the development of the follow-up hydrogen energy industry and the operation of hydrogen fuel cell vehicles.
