With the transformation of the global energy structure and the development of a low-carbon economy, the application of hydrogen energy in the field of transportation has been widely concerned. This paper analyzed the existing situation of hydrogen energy in the field of transportation both in China and abroad, shared the research ideas of China’s typical hydrogen energy application cases, and discussed the current situation and future development of hydrogen energy in the transportation field of China. By analyzing the implementation of the “Hydrogen into Ten Thousand Homes” science and technology demonstration project in Shandong Province, the problems faced by hydrogen energy applications in the field of transportation were explored, and the future development trend was predicted.
