What is deep underground energy storage?
Deep underground energy storage is the use of deep underground spaces for large-scale energy storage, which is an important way to provide a stable supply of clean energy, enable a strategic petroleum reserve, and promote the peak shaving of natural gas.
What is underground thermal energy storage?
Underground Thermal Energy Storage (UTES) A thermal energy storage is a system that can store thermal energy by cooling, heating, melting, solidifying or vaporizing a material , such as hot-water, molten-salt or a phase-change material. Sensible heat storage (SHS) relies on the temperature variation of a solid or liquid (e.g. water).
Can deep underground energy storage be developed in China?
The solution to these key scientific and technological problems lies in establishing a theoretical and technical foundation for the development of large-scale deep underground energy storage in China. 1. Introduction China must urgently transition to low-carbon energy consumption in order to meet the challenges of global warming.
What is the future of underground energy storage?
2023: Research directions in UHS and other underground energy storage technologies further expanded, emphasizing enhancing storage efficiency, ensuring safety, and maximizing the renewability of stored energy.
Do Underground Technologies still have room for future improvements?
The described underground technologies still have plenty of room for future improvements, especially in what relates to efficiency and new developments of technologies, their costs and economics aspects. Criteria for selecting underground reservoirs are very important for the success of an energy storage facility.
Why is the underground a good place to store thermal energy?
The underground is suitable for thermal energy storage because it has high thermal inertia, i.e. if undisturbed below 10-15 m depth, the ground temperature is weakly affected by local above ground climate variations and maintains a stable temperature [76, 77, 78].
