6 FAQs about [Cave conditions for compressed air energy storage]
How stable is a lined rock cavern for underground compressed air energy storage?
The long-term stability of a lined rock cavern (LRC) for underground compressed air energy storage is investigated using a thermo-mechanical (TM) damage model. The numerical model is implemented in COMSOL Multiphysics, and TM modeling is verified by the existing analytical solution in the case of no damage.
What is the storage capacity of air exergy in the cavern?
Depending on different CAES systems and operations, storage capacity of air exergy in the cavern varies. In this section, taking the Huntorf CAES plant as a case study, exergy storage capacity of the compressed air in the cavern are evaluated in different operational scenarios and heat transfer conditions.
Are caverns suitable for compressed air storage?
Of these options for air storage, Donader and Schneider pointed out that caverns are particularly suitable for flexible compressed air storage operation with high flow rates and frequent cycles , because caverns have one/serval large open space/spaces compared to porous rock which consists of a large number of pore spaces.
How much air pressure does a storage cavern have?
A storage cavern was located at more than 450 m underground in rock salt, with a storage volume at over 500,000 m3. Air storage pressure is about 7.4 MPa, and at full decompression, air pressure is about 4.5 MPa. Note that these two commercial CAES facilities were always be near an energy source or demand.
Does a cavern have a total exergy capacity and power rating?
Thermodynamic responses of the compressed air in the cavern determine the total exergy capacity and power rating of the CAES system. This investigation considers two cavern operation modes of storing compressed air, including uncompensated isochoric air storage and compensated isobaric air storage.
How can large-scale energy storage be implemented in salt caverns?
Compressed air and hydrogen storage are two main available large-scale energy storage technologies, which are both successfully implemented in salt caverns . Therefore, large-scale energy storage in salt caverns will also be enormously developed to deal with the intermittent and fluctuations of renewable sources at the national or grid-scale.
