Research of Hydrogen Energy Storage under the New Power System
Under the guidance of the"double carbon"goal,new energy will gradually replace fossil energy,and new energy is mainly wind power and solar energy,which is unstable and intermittent,so it is necessary to use energy storage to improve the stability of new energy.At the same time,the global energy use has been developing in a low-carbon direction,from biomass,to coal,oil,natural gas to hydrogen energy,the hydrocarbon ratio has been decreasing.Under the new power system,hydrogen energy storage has unique advantages of ultra-high energy density compared with traditional electrochemical energy storage,thermochemical energy storage,thermal energy storage,compressed air energy storage,flywheel energy storage,pumped storage energy storage,superconducting energy storage,etc.Up to now,the United States,Germany,Japan,China and other countries have released national hydrogen energy development strategies,and hydrogen energy storage can be said to be an important carrier for the terminal to achieve green and low-carbon transformation.Although the advantages are obvious,the development form and development path of the hydrogen energy storage industry need to be further explored.Based on the current situation of energy storage at home and abroad,the development of hydrogen energy industry,and the key technologies of hydrogen energy,this paper discusses the characteristic advantages and key technologies of hydrogen energy storage,so as to provide a valuable direction for the development of hydrogen energy industry.
