Conclusion: Hydrogen energy models will accelerate after the Winter Olympics
The development of new energy vehicles is one of the current mainstream trends, among which hydrogen energy vehicles have good environmental compatibility, high energy conversion efficiency, low noise, long mileage, short refueling time, no need to charge and other characteristics, and have great development potential.
As we all know, international competitions have always been an important window for hosts to showcase humanities and technology. All new energy models were used in the Winter Olympics, especially hydrogen fuel cell models, which showed that the country attaches great importance to hydrogen energy models.
In important documents such as the "Outline of the National Innovation-driven Development Strategy" previously released, it is clearly mentioned that hydrogen fuel vehicles should be vigorously developed. By 2030, the mainland will achieve the goal of 2 million hydrogen fuel cell vehicles. In addition, the Society of Automotive Engineers of China has predicted that by 2030, the output value of the mainland hydrogen energy vehicle industry is expected to exceed the trillion yuan mark.
During the Winter Olympics, hydrogen fuel cell vehicles will frequently appear in the public eye, I believe that after the Winter Olympics, the society's familiarity with hydrogen fuel cell vehicles will be greatly improved, which will accelerate the large-scale landing of this model in China.
