Abstract: In recent 10 years, German biogas industry has played an important role in its national strategy and energy system construction, it also has been the leader of the global new energy industry development. Based on German new energy development, the authors researched the development status and successful experience of German biogas engineering, and made a comprehensive introduction from the aspects of legal policy, project distribution, installed capacity, industry regulation and biogas slurry and residue utilization. Through the research and analysis of German biogas engineering system, guidance and reference were provided to the further development, application and promotion of biogas technology in China. At the same time, suggestions that suit the development of new energy in China were proposed combined with the realities of China.
