Mobile WebSiteShanghai and Wuhan have successively opened demonstration lines for hydrogen energy buses, which have drawn the attention of the media and the public. Hydrogen vehicles have once again entered the public eye. Just as 8 years ago, hydrogen vehicles served the Beijing International Olympic Games, Shanghai World Expo and other major international events.
"From the perspective of power-electric safety, the development of hydrogen-fired fuel cell vehicles - including hydrogen-electric hybrid vehicles - is also a good choice for solving the safety problems of electric vehicles. For more than a year, Foshan, Guangdong, Xinbin, Liaoning Hydrogen bus demonstration lines in many cities and towns in China such as Jiangsu Rugao, Chengdu, Shanxi Datong, Hebei Zhangjiakou, Zhengzhou, Shanghai, Wuhan, etc. are all trial operation, indicating that fuel cell vehicles are breaking ice!"
"The fuel cell vehicle - the most strategic breakthrough of new energy vehicles" author, researcher-level senior engineer Cheng Zhenduo revealed to the new energy observation.
Since the summer of this year, there have been frequent fire accidents in domestic electric vehicles. The number of electric vehicle fires that occurred in August and September alone exceeded the total number of electric vehicle fires in 2017. In the context of the rapid growth of domestic electric vehicles, Electric vehicle safety accidents have attracted the attention of industry professionals: they cannot pursue higher energy density to obtain more subsidies, but ignore the most fundamental safety attributes of power batteries.
At the recent global travel conference held recently, Changjiang Motor believes that the biggest problem encountered by electric vehicles in replacing fuel vehicles is mileage anxiety, charging anxiety, and other inconveniences and pain points. This will solve the problem of a power life. The future direction may be hydrogen fuel, which is the extension of electric vehicles. Recently, there have been many problems with the battery, and the media is also very concerned. There is a balance between the energy density and the cruising range of the battery used in electric vehicles. The excessive pursuit of energy density leads to an increase in battery cost and a risk on the other hand. Electric vehicles are electrical products that balance the degree of electrical products, energy density and product safety.
The next step is to solve the problem of how to increase the power of the electric vehicle through hydrogen fuel or other means. If the power problem of an electric vehicle cannot be completely solved, competition for a conventional car cannot be achieved. Fuel cells and lithium batteries go hand in hand to solve many problems in the development of electric vehicles. Because the breakthrough of lithium battery core technology is not possible, and the fuel cell has achieved a stage breakthrough. The Yangtze River electric bus, which is trial run in Foshan, has been equipped with a hydrogen fuel cell, which can be used for a range of up to 600 kilometers. As electric vehicles continue to break through the challenges they face and overcome, becoming mainstream products becomes a natural outcome.
After Foshan took the lead in entering the hydrogen-powered car era a year ago, Wuhan also entered the hydrogen-powered car era a year later. On September 28th, the first batch of hydrogen fuel cell power buses jointly developed by Wuhan Taige Hydrogen Vehicle and Wuhan Kaiwo New Energy Co., Ltd. were trial run on Wuhan Donghu 359 bus line. The first hydrogen refueling station in Wuhan, which was built by Wuhan Zhongji Hydrogen Energy, was also opened at the same time. This indicates that the hydrogen fuel cell power bus in Wuhan has entered the commercial demonstration stage.
The hydrogen refueling station near the terminal of Wuhan No. 359 Road has a daily hydrogenation capacity of 300 kg, which can meet the hydrogenation demand of about 50 buses. The hydrogen fuel cell bus has a cruising range of more than 400 kilometers. The vehicle does not produce any pollutants such as carbon dioxide during driving, and only discharges water of pure water level to achieve true zero pollution.
Hydrogen fuel cell vehicles are one of the important directions for the development of new energy vehicles. The automobile industry is a pillar industry in Wuhan. The development of hydrogen fuel cells has important strategic significance for Wuhan. In the spirit of “promoting the development of hydrogen fuel cell vehicle industry and infrastructure first”, Zhongji Hydrogen can build a new industrial by-product hydrogen high-purity hydrogen plant in Yunmeng and Qianjiang, with a total production capacity of 88 million cubic meters per year, which can meet about 4500. The hydrogenation demand for hydrogen fuel cell buses is the main source of hydrogen fuel cell vehicles operating in Hubei Province in the next 3-5 years. At the terminal of the hydrogen refueling station, Zhongji Hydrogen can cooperate with PetroChina to rebuild and expand the hydrogen refueling station by using the refueling and gas station, effectively utilize the urban land resources and achieve rapid promotion. It plans to build and produce 100 hydrogen refueling stations in the next five years.
Evaluate the technical level of a battery, there are many standards, including: First, the energy density, the same size of the battery who installed more electricity; Second, the cost, can install the same amount of electricity, to see who is cheap; Third, availability, Such as lithium battery charging time, safety, consistency and so on.
In this sense, the next step in the power battery is lithium or fuel cells, or solid-state batteries, or other batteries that are being researched in the laboratory. Further research, experimentation, demonstration, trial, and promotion are needed to find a more balanced More suitable solutions need to be promoted and promoted with scientific attitudes and market means.
