Hydrogen is considered as a clean and multi energy energy carrier, which is sustainable in human beings It plays an important role in the development of energy system. It is understood that the key special project of the national key research and development plan "Science and Technology Winter Olympics" led by Tsinghua University - "Hydrogen Energy Travel" key technology research and development and application demonstration scientific research project team, took the opportunity of serving the 2022 Beijing Winter Olympics to develop three models. What is the hydrogen bus How to help The Winter Olympics, Realize green zero carbon travel? Recently Yang Fuyuan, the person in charge of the project team, introduced that the hydrogen fuel cell bus can High carrying energy density, therefore Endurance The mileage is relatively long, and the hydrogen energy fuel produced by electrolysis of water does not involve any petrochemical energy and will not produce carbon emissions, so it is 100% green energy.

"In the cold weather of - 35 ℃, the hydrogen fuel cell bus can provide rapid thermal management, and the temperature of the car can rise to 10 ℃ within 25 minutes." Yang Fuyuan said that the key technology and safety assurance technology of the whole industry chain of "hydrogen energy travel", namely, production, storage, transportation, processing and use, will be the demonstration project of global hydrogen fuel cell vehicles and hydrogen energy infrastructure so far, It is of great significance in the history of hydrogen energy development in China and even the world.

Yang Fuyuan introduced how to ensure safety in the use of hydrogen energy, and the project team adopted Three measures ， everything Hydrogen energy Containers and Piping, on The structure shall be able to withstand enough strength to prevent leakage Dew; two It is necessary to prevent leakage, agglomeration, ignition and strict control Hydrogen energy Quality and strict process management; Third Once it happens Hydrogen energy Leakage Try to avoid explosion, etc. In addition, in order to prevent the use of vehicles for the Winter Olympics Hydrogen energy Leakage, The project team also Specifically for hydrogen The fuel cell bus has been completed 70 MPa gas cylinder Side impact test ， test The results show that The cylinder structure design is safe, and the cylinder is not damaged 。

Yang Fuyuan introduced that fuel cell vehicles are a scene of hydrogen energy development and Application: key technologies Products, as well as other products in the industrial chain, can be used continuously after the Winter Olympics. (Wang Lianxiang)
