Compressed air energy storage underground stone chamber

Why is split lining structure used in underground compressed air storage caverns?

Split-lining structure was applied for the airtight lining of the underground compressed air storage cavern, to assure the safety and economic efficiency of pressurized air storage under the various geological conditions. In-situ tests were performed in actual caverns, to verify the design of split lining structure in practice.

What is the airtight lining structure of underground compressed air storage cavern?

To ensure pressure resistance and air-tightness, the airtight lining structure of the underground compressed air storage cavern is of composite construction comprising split lining and airtight sealing material. Fig. 1 is a general view of the structure.

Can compressed air be stored in rock caverns?

A pilot plant for the adiabatic storage of compressed air is currently being constructed in Switzerland (Section 4.7). Compressed air storage in rock caverns—particularly in lined rock caverns—could be interesting in future for countries which are not able to construct salt caverns but have adequate hard-rock potential.

What is compressed air energy storage (CAES)?

Currently, the expansion of renewable energies requires the development of fast and flexible energy storage systems. Electricity storage will play a crucial role in enabling the next phase of the energy transition. Compressed Air Energy Storage (CAES) is one of the systems that can contribute to the penetration of renewable energy sources.

Is compressed air energy storage in aquifers a potential large-scale energy storage technology?

Compressed air energy storage in aquifers (CAESA) has been considered a potential large-scale energy storage technology. However, due to the lack of actual field tests, research on the underground processes is still in the stage of theoretical analysis and requires further understanding.

Does Mount Simon Sandstone have compressed air energy storage?
