In order to further explore the feasibility of key technologies, related products, markets, and policy measures in the hydrogen energy industry at different time nodes, an analysis framework for the development of the hydrogen energy industry was constructed based on industrial technology road-map. The incoPat patent database was used to clarify the current development status of the hydrogen energy industry through technology patent retrieval and analysis. Adopting questionnaire survey and expert interview afterwards,the development trend of China’s hydrogen energy industry is predicted and depicted from aspects of industrial environment, main products, key technologies, etc. Based on above predictions and depictions,a roadmap for the development of China’s hydrogen energy industry is drawn. In combination with the construction practice of Changping “Energy Valley”, suggestions for industrial development are systematically put forward, such as increasing technological research and development in the field of hydrogen production using renewable energy, actively promoting pilot demonstrations, accelerating the construction of a national hydrogen energy supply system and a whole industry chain system of hydrogen industry with green hydrogen as the core, improving the standard system, and strengthening international cooperation.
