[Explanation] On December 28, the world's first hydrogen energy city train rolled off the assembly line in Chengdu, Sichuan.
It is reported that the train has a built-in "hydrogen power" system, with a maximum speed of 160 kilometers per hour, and a battery life of 600 kilometers can be achieved with one hydrogen refueling.
[Explanation] The front end of the train adopts an all-inclusive design, and the dark blue body matches the hydrogen symbol with "H2" as the core, highlighting its green and low-carbon characteristics.
The train uses a combination of hydrogen fuel cells and supercapacitors for energy supply. The energy is generated by the electrochemical reaction of hydrogen and oxygen in the hydrogen fuel cells. The reaction product is only water without any nitrogen and sulfur by-products.
[Same period] Cui Jianghan, head of hydrogen power system research and development of hydrogen energy city trains
Like the hydrogen-powered city car we are seeing now, its energy is replenished through a hydrogen refueling station.
For example, if this car is applied to a commercial line, we will set up a hydrogen refueling station in the middle or at the starting station or the terminal station. Each car will have one or two hydrogen refueling ports. This depends on the actual situation. design needs.
Each car can be refueled at the same time, basically it takes a short time to fill up a car.
[Explanation] Entering the train compartment, the whole car is dominated by dark blue, embellished with light blue and black, and the design of "hydrogen element" can be seen everywhere.
[Same period] Sun Shijie, designer of hydrogen energy urban trains of CRRC Changchun Co., Ltd.
The interior design of the train mainly embodies the element of hydrogen, for example, there is a logo of hydrogen on the side of the car.
The train uses smart windows, which can inquire about the regional characteristics of Chengdu and can also be inquired about.
[Explanation] It is understood that the hydrogen energy city train also integrates many intelligent cutting-edge technologies.
In terms of intelligent control, the vehicle adopts the highest level of automatic driving technology, endowing the vehicle with intelligent driving functions such as automatic wake-up, automatic start and stop, and automatic return to the warehouse.
[Concurrent] Li Hongwei, Deputy General Manager of CRRC Changchun Rail Vehicle Co., Ltd.
Our car is unmanned (driving), fully automatic start, automatic operation, automatic stop, automatic return, without human intervention in the whole process, the vehicle can realize automatic operation.
Through the provision of hydrogen power, we can guarantee a long-term continuous operation of 600 kilometers.
According to the planning of normal city-area lines, it can meet the requirements of operating mileage in one day.
[Explanation] Because of getting rid of the shackles of catenary operating conditions, hydrogen energy urban trains can be widely used in existing non-electrified line sections, greatly improving the application range of urban vehicles, while avoiding the huge investment in infrastructure and electrification. maintenance costs.
[Concurrent] Li Hongwei, Deputy General Manager of CRRC Changchun Rail Vehicle Co., Ltd.
The equipment outside our car has been reduced a lot, especially the high-voltage system, pantograph and other equipment, and some streamlining has been done.
Taking a 40-kilometer-long line as an example, if the ground length is 30 kilometers and the underground length is 10 kilometers, our entire one-time infrastructure cost will save more than 1 billion yuan.
Therefore, based on the cost of the whole life cycle, the overall cost of our hydrogen energy city car will be reduced by more than 10% compared with the traditional city car.
In the future, we also hope to realize the commercial application of our product in urban railroads in Chengdu.
