"Hydrogen"-two-dimensional animation short video series, based on "science and technology, hydrogen energy, life, contact, function, audience and other key words to conceive the content, a total of ten short videos. Explain in detail what hydrogen energy is, how hydrogen energy is produced, and the cold resistance, environmental protection, convenience, safety, etc. of hydrogen energy production, storage, transportation, and hydrogen fuel buses. MG animation is used to publicize the popular science knowledge of hydrogen energy, and dynamic graphics are used to integrate graphic design and animation design to simply and fully push the relevant knowledge of hydrogen energy to the viewer. In order to solve the problems of unfamiliar knowledge in the field of new energy and difficult to understand professional terms. The time length of each short film is controlled at about forty seconds, which conforms to the time length of the audience receiving short video information and the endurance of watching. By condensing and summarizing the title of each short film and using a form of rhetorical question to arouse the public's curiosity and explore the problem, the image design of scientific research assistant "Little Hydrogen" is used to explain to the audience the relevant knowledge of hydrogen energy, the operation of its application in the Winter Olympics, and the development prospect of hydrogen energy in people's lives. The sub-themes of the ten short films are: 1. Hydrogen energy travel for the Winter Olympics of science and technology; 2. Is hydrogen energy equal to direct combustion of hydrogen? 3. Can you breathe hydrogen? 4. Will the carrier that transports hydrogen and stores hydrogen fly? 5. Does hydrogen fuel not burn and explode as vehicle power? Why is hydrogen "green? 7. Will hydrogen energy be exhausted one day? How is hydrogen used in cars? 9. Will the hydrogen battery car be frozen? 10. What is the significance of the" hydrogen energy travel "project?
