For many athletes participating in the Beijing Winter Olympics, the first impression of the "Green Winter Olympics" comes from the hydrogen fuel cell vehicles they ride every day. As the main force of the event service vehicles in Zhangjiakou, hydrogen fuel cell vehicles shuttle between the Winter Olympic Village and the venues, becoming a beautiful landscape outside the venue.
"Hydrogen" forces to ensure the green Olympic Games
The hydrogen fuel cell vehicle used this time is a scientific and technological achievement of independent innovation in the mainland, running smoothly, quietly and noise-free, and more importantly, it "eats" hydrogen, discharges water, clean and efficient. Compared with conventional energy vehicles, hydrogen fuel cell vehicles can reduce carbon dioxide emissions by about 70 kg per 100 kilometers traveled.
According to statistics, during the Beijing Winter Olympics, nearly 2,000 hydrogen fuel cell connecting vehicles were put into the three major competition areas of Beijing, Yanqing and Zhangjiakou, with a cumulative operating mileage of more than 3.2 million kilometers and a carbon reduction of more than 2,600 tons.

"Among them, yihuatong fuel cell engines account for 64% of the models, operating mileage of more than 2.6 million kilometers, accounting for 81%, carbon reduction of more than 2200 tons, accounting for 85%." Yu Min, executive deputy general manager of Beijing Yihuatong Technology Co., Ltd., proudly told reporters.
In the cold climate of Zhangjiakou in winter, in order to meet the connection needs during the Beijing Winter Olympics and adapt to the ultra-low temperature environment, Zhangjiakou Yihuatong Power Technology Co., Ltd. has developed the "key technology of rapid cold start of fuel cell system in -30 °C environment", applying gradient heat transfer technology and electrochemical rapid heat production technology to break through the low temperature starting limit of graphite plate.

"The application of this technology can achieve a rapid start of the rated power in 99 seconds in the environment of -30 °C, solving the problem of rapid start-up of fuel cells in low temperature environments." Yu Min said that with the strong blessing of scientific and technological strength, during the Beijing Winter Olympics, all vehicles equipped with Yihuatong engines successfully completed the connection task, providing strong support for the green Olympic Games.

Due to the high standards and high quality of the winter (paralympic) Olympic Games service guarantee work, on March 18, Yihuatong received a letter of thanks from the Beijing 2022 Winter Olympic and Paralympic Games Organizing Committee. On April 19, the Summary and Commendation Conference of the Hebei Provincial and Beijing Winter Olympic Organizing Committee of the Beijing Winter Olympic and Paralympic Winter Games was held, at which the "Decision of the CPC Hebei Provincial Committee and the People's Government of the Hebei Provincial People's Government and the Beijing Winter Olympic Organizing Committee on Commending the Advanced Collectives and Advanced Individuals of Hebei Province for the Beijing 2022 Winter Olympic and Paralympic Winter Games" was read out, and Yihuatong was commended.
Data empowers smart mobility
"At present, hydrogen fuel cell engines have been widely used in the field of commercial vehicles, and this year, we will promote them in the direction of muck trucks and medium and long-distance tractors." Yu Min believes that hydrogen fuel cell vehicles have the characteristics of long mileage of traditional fuel vehicles, high refueling efficiency and zero emission and no pollution of lithium battery vehicles, and the market prospect is very broad.
Data empowerment, post-Olympic era, hydrogen energy travel will be more intelligent.
Hydrogen sees the future of intelligent big data analysis application platform.
According to reports, with the support of the Hebei Provincial Science and Technology Winter Olympics Project, Yihuatong has independently developed a hydrogen future intelligent big data analysis application platform, which can conduct comprehensive analysis and characteristic working condition extraction based on Zhangjiakou operation data, analyze and simulate and investigate the actual vehicle data of some hydrogen fuel cell vehicles in the high-cold area of Zhangjiakou, and analyze the operating vehicle backhaul working condition data through big data and artificial intelligence and other technical means to help improve the quality of products, and by monitoring the current, voltage, temperature and pressure of the on-board hydrogen system and other parameters , timely identification of abnormal information.
"In the post-Olympic era, with the development of industry and the improvement of technological maturity, hydrogen energy is likely to replace other types of energy in the field of power generation and drive, and play a role in various application scenarios of sea, land, air and space." For the future development of the hydrogen energy industry, Yu Min is full of confidence.
Science and technology support industrial development
Confidence not only comes from good market prospects and the rapid development of technology, but also from the strong support of policies.
According to Shi Tiezhu, deputy director of the High-tech Department of the Science and Technology Department of Hebei Province, in the post-Olympic era, the Provincial Science and Technology Department will implement special projects for new energy science and technology innovation and support the development of key core technologies of new energy. Focus on the major needs of hydrogen energy efficient utilization, photovoltaic power generation, wind and solar storage and transportation and other fields, gather and integrate the advantages of central units, universities, institutes and enterprises in Hebei, organize and carry out key core technology research on wind energy, solar energy and advanced energy storage, break through key technologies such as efficient and low-cost hydrogen production, storage and transportation, refueling and fuel cells, and cultivate the first-mover advantage of new energy industry technology。
At the same time, we will focus on the scientific and technological needs of the "two districts" construction of the capital of Zhangjiakou, integrate and transform a number of high-level scientific and technological achievements inside and outside the province, especially in the Beijing-Tianjin region, and support the construction of Zhangjiakou renewable energy demonstration zone and hydrogen energy demonstration city in the field of new energy.

"Not only in the field of new energy, during the preparation of the Beijing Winter Olympics, the Provincial Department of Science and Technology promoted the work of the Winter Olympics with high standards and high quality, organized the implementation of special projects for the Winter Olympics of science and technology, and supported more than 100 projects in the past three years, and a large number of advanced technological achievements have been practically applied in venue operation and maintenance, meteorological transportation, event guarantee, ice and snow industry development, and smart city construction." Feng Shijun, director of the Science and Technology Winter Olympics Special Class of the Science and Technology Department of Hebei Province, told reporters that among them, 46 independently developed project results successfully guaranteed the operation of the Winter Olympic Games, and 53 projects are injecting new momentum into the development of the ice and snow industry in Hebei Province.
"In the next step, we will continue to do a good job in tracking these projects, and at the same time increase the introduction and docking of the achievements of the Beijing-Tianjin Science and Technology Winter Olympics, accelerate the promotion and industrialization of the results, and provide strong scientific and technological support for the economic and industrial development of the post-Olympic era." Feng Shijun said.
