Hydrogen fuel cell vehicles have become the main force of transportation for the Winter Olympics
"Since the start of the Winter Olympics, a total of 816 hydrogen fuel cell vehicles have provided transportation services for the Winter Olympics, achieving zero carbon emissions in transportation activities."
Wu Zhiquan said that there are three models of hydrogen fuel cell vehicles serving the Winter Olympics, namely Toyota Mirai passenger cars, Toyota Costa minibuses and 12-meter buses jointly developed by Toyota-Foton. Compared with the same class of fuel vehicles, the three hydrogen fuel cell vehicles can reduce carbon dioxide emissions per 100 kilometers by about 18.79 kg, 47.01 kg and 57.86 kg respectively.
In the harsh winter conditions, battery cars may appear "lying down" phenomenon, and hydrogen fuel cell vehicles can withstand the test of severe cold. Wu Zhiquan said that 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.
Talking about the hydrogen fuel cell vehicles used in the Winter Olympics, Kenji Quan, executive deputy general manager of Toyota Motor Research and Development Center (China), told the surging news reporter that there were 140 second-generation Toyota Mirai passenger cars and 107 Toyota Costa minibuses at the Beijing Winter Olympics to provide travel protection for athletes and staff. Among them, toyota Mirai passenger cars are mainly used as VIP reception cars, and minibus Costa is mainly used as a VIP and athletes car between high-speed rail stations, Winter Olympic Villages, Genting stadiums and large jumping stadium groups, and as an auxiliary car in the process of torch relay and awards.
Crustal is developed, assembled and tested in China. Kenji Kwon said that the car has been researched and developed in China since 2019 for the use of the Winter Olympics, developed by Chinese engineers at the Toyota China R&D Center, all vehicles are produced in China, and the vehicle parts are provided by Chinese suppliers. The car has been tested for more than 50 days in Heihe, Yanqing, Zhangjiakou, Hubei Mountain, etc. for more than 50 days.
Kenji Kwon said that at present, hydrogen fuel cell vehicles will have greater application space in the field of commercial vehicles. On the one hand, the volume and weight of commercial vehicles are larger, and the use of hydrogen fuel cell vehicles can reduce the battery weight of the additional burden, and the time for charging hydrogen fuel is significantly shorter than the battery charging time. On the other hand, the driving route of commercial vehicles is relatively certain, and it is easier to lay out hydrogen refueling stations.
For the development of the hydrogen energy industry, Kenji Kwon said that the Chinese government attaches great importance to the development and utilization of hydrogen energy, and has formulated a series of industrial development policies, and the government has given great attention and support to industry enterprises. In the future, all parties in the upstream and downstream of the hydrogen energy industry chain need to further strengthen cooperation and jointly explore the development of hydrogen energy.

"Green electricity to green hydrogen" provides clean hydrogen fuel for the Winter Olympics
Hydrogen fuel cell vehicles work by sucking oxygen from the atmosphere and chemically reacting with hydrogen in a fuel cell reactor to extract electrical ions and then boost the power used for vehicle drives. This process produces only clean water and does not produce any carbon dioxide emissions.
For hydrogen fuel cell vehicles, hydrogen fuel is an essential consumable. According to reports, the 312 hydrogen fuel cell vehicles invested in the two competition areas of beijing at the Winter Olympics have used about 42.04 tons of hydrogen since the opening of the Winter Olympics on February 4 to February 14.
Zhang Yan, deputy general manager of Huanyu Jinghui Jingcheng Gas Technology Co., Ltd., said that as a hydrogen supply guarantee unit for hydrogen fuel cell vehicles in the Winter Olympics of Science and Technology, Huanyu Jinghui cooperated with Jingneng Group to use the "green electricity" generated by photovoltaics and wind energy to produce hydrogen to achieve "green electricity to green hydrogen".
In the electronic grade 500m/h ultrapure hydrogen R&D and production workshop of Huanyu Jinghui, the reporter saw that the workshop was equipped with electrolyzers and purification equipment, and the roof of the workshop was equipped with photovoltaic power generation equipment. Zhang Yan introduced that green electricity is obtained through photovoltaic power generation, in the electrolytic cell, the water will be electrolyzed into oxygen and hydrogen, and after the purification equipment adsorbs impurities and separates oxygen, hydrogen with a purity of 99.999% will be obtained.
Zhang Yan said that Huanyu Jinghui provides 1.5 tons of green hydrogen energy for the Beijing Winter Olympics every day, which is transported through a special trailer, and each trailer can store 4,000m and about 350 kilograms of hydrogen. Huanyu Jinghui has more than 100 trailers, providing hydrogen energy support for the Beijing Winter Olympics 24 hours a day.
In an interview with the surging news reporter, Zhang Yan said that each trailer is equipped with sensors, and the data will be transmitted back to the command center in real time, and the command center is responsible for dispatching: "At the hydrogen refueling station of the Winter Olympics, when the hydrogen energy is almost used up, the big data platform for hydrogen energy production, storage, transportation and vehicle operation and scheduling will show that it will be dispatched in time to ensure the timely supply of hydrogen." ”

The Winter Olympics will promote the further development of Beijing's hydrogen energy industry
While hydrogen energy serves the green Winter Olympics, Beijing's hydrogen energy industry has also been further developed by relying on the opportunity of the Winter Olympics.
Wu Zhiquan said that in order to realize the use of hydrogen fuel cell vehicles at the Winter Olympics, Beijing has further tried to explore the revision of hydrogen energy and hydrogen fuel cell vehicle industry standards, the construction process of hydrogen refueling stations, and the hydrogen energy safety guarantee mechanism, and has achieved certain results.
First of all, promote the revision of the "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" and other standards, and incorporate the relevant technical requirements of fuel cell electric vehicles equipped with 70MPa and III. bottles into the relevant technical requirements of fuel cell electric vehicles; organize Toyota and other enterprises to share technical experience, provide technical support for the formulation of relevant standards, and complete the first domestic IV. bottle standard ("Vehicle compressed hydrogen plastic liner carbon fiber fully wound gas cylinder"). For the first time, it has obtained certification for a 70Mpa hydrogen energy vehicle equipped with an IV-type bottle. The world's first standard for hydrogen fuel cylinders for handheld flares has been formulated, ensuring the reliability, safety and consistency of the industrial production of torch green energy cores.

Secondly, the Beijing Winter Olympics promoted the improvement of the hydrogen refueling station construction process. The safety level of hydrogen refueling stations is relatively high, and the relevant technologies are still in the stage of continuous development and improvement. 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.
In addition, the Beijing Winter Olympics promoted the establishment of a hydrogen energy safety guarantee mechanism. The competent departments of all aspects and fields 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 guarantee for the development of the follow-up hydrogen energy industry and the operation of hydrogen fuel cell vehicles.
Wu Zhiquan also said that at present, Beijing is implementing the development plan of hydrogen energy and hydrogen fuel cell vehicle industry, and actively promoting the construction of the Beijing-Tianjin-Hebei fuel cell vehicle demonstration city cluster. Strive to establish an industrial ecology of "independent technological innovation, sustainable industrial development, and regional integration" at the end of the "14th Five-Year Plan" period, and build an industrial cluster for the manufacture of key components and equipment for fuel cell vehicles.
