Technical Status and Development Trends of Hydrogen Energy Industry Chain Technology in China
Under the goal of"dual carbon",hydrogen energy has the advantages of rich sources,wide applications,diverse utilization forms,high calorific value of combustion,and clean&environmental protection,and will play an important role in China's energy transformation.China's hydrogen energy industry is still in the early stage of development and strengthening research on the current situation of the hydrogen energy industry chain as well as grasping development trends will help accelerate energy transformation.By reviewing the current status of key technologies in each link of the hydrogen energy industry chain,comparing and analyzing the advantages and disadvantages of various technologies and their development trends.The paper finds that the"coal to hydrogen+CCUS"is the main technology in China in the short term,and electrolytic water coupled renewable energy generation will be the mainstream in the long run,and microbial hydrogen production is expected to be auxiliary.Hydrogen energy storage and transportation is showing a diversified development trend and large-scale,long-distance,and continuous transportation will be carried out through pipelines.The cost of hydrogen generation,storage and transportation will decrease gradually and the use of hydrogen will be gradually expanded to industry,transportation,electricity,construction,and other fields.It is suggested to improve the overall planning and layout of the hydrogen energy industry,strengthen core technology research and development,steadily promoting infrastructure construction,and achieve low-cost production,storage,transportation,and utilization of hydrogen energy.
