In the 21st century, the application of hydrogen energy and development of hydrogen energy industry have received extensive attention from the society. From the history of the Earth formation and geophysical data, the Earth's interior is a hydrogen energy reservoir. Data from Continental Science drilling suggest that large earthquakes may generate seismic waves that surround the globe and move fracture zones in the Earth's crust and mantle to release gas from the Earth's interior. After earthquakes, the Earth can release gases such as hydrogen, helium and methane, which will rush up through the mantle fracture zones to the upper crust. If there are rock layers with low permeability in the upper crust covering the upwelling gas, they may become a hydrogen energy reservoir in the deep crystalline rock. In China, there may be such deep hydrogen energy storage in the eastern Qinghai-Tibet Plateau, which deserves further study.
