Hydrogen energy will play an important role in China''s industrial structure layout, energy structure adjustment, and new energy development and utilization. During the two sessions in March 2021, hydrogen energy was officially included in the "14th Five-Year Plan" and the long-term goal of 2035.
Driven by China''s long-term energy transition strategies, the construction of large-scale clean energy power stations, such as wind, solar, and hydropower, is advancing rapidly.
Other storage methods like solid-state and chemical hydrogen storage, metal hydrides, etc. are still in the early stages of development. Each of the storage methods of hydrogen comes with specific pros and cons, and a suitable storage method for hydrogen depends on the specific application, energy density requirements, safety
Energy is essential in our daily lives to increase human development, which leads to economic growth and productivity.
