The sales of fuel cell vehicles are expected to double this year. Academicians and professors from Jiaotong University have released good news on green hydrogen. Ding Wenjiang, an academician and professor of solid-state hydrogen storage at room temperature and pressure
"Academician Ding Wenjiang's team has been tirelessly researching and conquering the solid utilization methods of hydrogen energy for many years. Academician Ding spoke well: the future of solid-state hydrogen storage lies in 'magnesium'. On the 15th, Xu Dingming, former counselor of the State Council and director of the Energy Bureau of the National Development and Reform Commission, connected to the Changning Campus of Shanghai Jiao Tong University via video, paying tribute to the experts who have made contributions in hydrogen energy utilization, believing that 'hydrogen' is on the battlefield and has a bright future.".
How can hydrogen be efficiently and safely loaded into vehicles to unleash the enormous potential of green new energy? On that day, it was the first national ecological day established by the country. From Academician Ding Wenjiang of Materials Science to Professor Yi Peiyun of Battery Science, they released good news about "green hydrogen" at the Shanghai Jiao Tong University Green Hydrogen Production and Finance Development Forum, which was called "Green Hydrogen". It is interesting that before these two people became familiar with driving hydrogen, Ding Wenjiang's team was intentionally planting flowers and unintentionally planting willows, and Yi Peiyun's team was even misunderstood as putting a hydrogen bomb in the car.
"I mainly study light metals. I started studying magnesium in 1983, and today I have been studying it for exactly 40 years. Magnesium, as a structural material, is very light. Perhaps like magnesium hydride, one magnesium atom carries two hydrogen atoms, which becomes the fate between" magnesium "and" hydrogen "and Ding Wenjiang." So, we started studying magnesium+hydrogen again 15 years ago. "
The Jiefang Daily Shangguan News reporter learned that Academician Ding Wenjiang created the National Engineering Research Center for Precision Forming of Light Alloys at Jiaotong University, and his team even made magnesium materials available for China's aerospace projects. Because magnesium has very active properties, when ground very finely, it becomes flammable and explosive. Therefore, the research team attempted to use multiple gases for safety protection, but none of them were successful.
At a time when mountains and rivers were no longer clear, they found hydrogen, which seemed to have the same temper. Unexpectedly, after combining through certain reactions, these two can actually coexist peacefully. As a result, hydrogen can be stored in magnesium alloy materials for long-distance transportation. Compared to traditional gaseous and liquid hydrogen storage, this not only completes storage and transportation at room temperature and pressure, but also has stronger safety, larger capacity, and higher density.
In fact, metal hydride hydrogen storage has entered the demonstration application stage abroad, while China is still in the commercial exploration stage, and the Ding Wenjiang team is in a leading position. Of course, hydrogen storage on solid media is convenient to operate, but it still faces the process and cost optimization of front-end hydrogenation and back-end dehydrogenation. According to the four major links of "production storage transportation refueling", hydrogen, whether solid or gaseous, liquid, etc., enters gas terminals such as hydrogen fuel cell vehicles through refueling stations, and smoothly reaches the downstream of the entire hydrogen industry chain.
Many years ago, many people regarded hydrogen fuel cells as car mounted "bombs". Yi Peiyun, a specially appointed professor at Shanghai Jiao Tong University, assistant dean of the School of Mechanical and Power Engineering, and chairman of Shanghai Hydrogen Chen New Energy Technology Co., Ltd., smiled and said, "We hydrogen workers used to have 'doubts about life' and even worried that the hydrogen era might be a technology scam."
However, it is precisely with zero emission hydrogen fuel cells as the breakthrough point that Yi Peiyun is pleased to say that the current global fuel cell vehicle ownership is about 67000, and China has about 13000. It is expected that the global fuel cell vehicle scale will exceed 10 million by 2030, and China will exceed 2 million. By 2050, the annual production of fuel cell vehicles in China is expected to reach 5.2 million, and with the addition of new energy vehicles such as lithium battery vehicles, traditional fuel vehicles will gradually withdraw from the historical stage. A carbon neutral hydrogen society will be fully built.
In the final dark before dawn, the trillion level new track requires the integration of industry, academia, and research. On the same day, the green hydrogen production and financing research center jointly launched by the school of Jiaotong University with Shanghai Energy and Environment Exchange, Shanghai High Efficiency Energy Internet Innovation Institute, Xinjiang New Energy Group, etc. was officially established. Academician Ding Wenjiang, director of the hydrogen science center of Shanghai Jiaotong University, served as the honorary director of the expert committee, and Hu Jie, a distinguished professor of Shanghai Jiaotong University, president of the School of Lifelong Education, and president of the Global Innovation Institute, served as the director of the special committee. Experts say that in 2022, 5009 fuel cell vehicles will be sold nationwide, and it is expected to exceed 10000 vehicles by 2023, achieving a doubling.
