In order to ensure energy supply and cope with climate change, a new round of energy transformation must be carried out. Hydrogen can play an important role in energy transformation with its high energy density and clean and low-carbon energy attributes. First of all, it clarified the development position of hydrogen energy in the transformation of energy. It pointed out that hydrogen energy is an energy carrier that promotes the large-scale development and utilization of renewable energy, and it is an energy medium that realizes the interconnection, complementation, and coordinated optimization of multiple energy networks. Secondly, the technical route for the development of the hydrogen energy industry is analyzed. Combining with the characteristics of China’s energy structure and development status, the development of the hydrogen energy industry should focus on the core advantages of clean, low-carbon, flexible and efficient, in the coordinated development of hydrogen and renewable energy, the clean production of industrial hydrogen, and the development of fuel cell technology. In addition, transportation power systems and distributed energy systems can give priority to promoting large-scale development.
