Hydrogen is considered to be a clean and versatile energy carrier and occupies an important position in the sustainable development of human energy system. It is understood that the national key research and development plan "Science and Technology Winter Olympics" led by Tsinghua University - the "Hydrogen Energy Travel" key technology research and development and application demonstration scientific research project team has developed three models to serve the 2022 Beijing Winter Olympics. How exactly will hydrogen buses help the Winter Olympics and achieve green zero-carbon travel? Recently, Yang Fuyuan, head of the project team, introduced in the guest program of the People's Network "People's Ice and Snow Ice and Snow Science and Technology Talk" that hydrogen fuel cell buses can carry high energy density, so the mileage is relatively long, and the hydrogen energy fuel produced by electrolyzed water does not involve any petrochemical energy and does not produce carbon emissions, so it is 100% green energy.
"In cold weather of minus 35 degrees, hydrogen fuel cell buses provide rapid thermal management, and the cabin temperature can rise to 10 degrees Celsius within 25 minutes." Yang Fuyuan said that the key technologies and safety assurance technologies of the whole industry chain of "hydrogen energy travel" production-storage-transportation-addition-use will be the demonstration projects of hydrogen fuel cell vehicles and hydrogen energy infrastructure in the world so far, which is of great significance in the history of hydrogen energy development in China and even in the world.
For how to ensure the safety of hydrogen energy in the use of the process, Yang Fuyuan introduced that the project team has taken three measures, one is the container and pipeline of hydrogen energy, in the structure to be able to withstand enough strength, so that it will not leak; the second is to prevent leakage, anti-agglomeration, anti-ignition, strict control of hydrogen energy quality, strict process management; third, once hydrogen energy leakage occurs, to avoid explosion and so on. In addition, in order to prevent hydrogen energy leakage problems in the use of winter Olympic project vehicles, the project team also specially did a 70 megapascal cylinder side crash test on the hydrogen fuel cell bus, and the test results showed that the gas cylinder structure was designed safely, and the gas cylinder was not damaged in any way.
Yang Fuyuan introduced that fuel cell vehicles are a scenario and application of hydrogen energy development, and the key technologies, products and other products in the industrial chain developed for the Winter Olympics can be used continuously after the Winter Olympics. (Wang Lianxiang)
