With the acceleration of global warming, the development of low-carbon energy has become an important task of the times. As a clean, low-carbon energy source, hydrogen energy has been valued and supported by the Chinese government. In 2021, the Chinese government's "Guiding Opinions of the State Council on Accelerating the Establishment and Improvement of the Economic System for Green, Low-Carbon and Circular Development" pointed out that it is necessary to establish an economic system for green, Low-carbon circular development, and strive to achieve the goal of "carbon peaking and carbon neutrality". This goal is of great significance for realizing China's high-quality sustainable development, alleviating the greenhouse effect, and building a community with a shared future for mankind. As a representative of clean energy, hydrogen energy will play an important role in the road to climate change and play a great role. However, the utilization of hydrogen energy in my country has just started. Due to the weak industrial foundation and imperfect industrial chain, fossil fuels are usually used in the production of hydrogen, so the consequences are self-evident. Therefore, the author describes in detail a variety of new energy hydrogen production technologies, compares them, and discusses the development status and application improvement directions of new energy hydrogen production technologies.
