Can a compressed air energy storage system replicate three critical operational conditions?
Strengths and Limitations This study presents the first integrated experimental platform capable of simultaneously replicating three critical operational conditions of compressed air energy storage (CAES) systems: geo-stress (up to 100 MPa), geological temperature (up to 300 °C), and cyclic gas pressurization (0–70 MPa).
What is compressed air energy storage (CAES) in underground lined rock caverns?
The compressed air energy storage (CAES) in the underground lined rock cavern is a promising long-term energy storage technology, while the mechanical and temperature responses during the cyclic process of gas charging and discharging are highly complicated.
What is compressed air energy storage (CAES)?
As a new type of energy storage, compressed air energy storage (CAES) is considered to be the most promising large-scale energy storage system [12, 13], which can effectively overcome the problems of small energy storage scale, complex site selection, and high construction costs.
What are the different types of underground compressed air energy storage caverns?
The main types of underground compressed air energy storage caverns are salt caverns, artificially excavated hard-rock caverns, and abandoned mineral cavern retrofit caverns. Salt caverns do not require lining due to their tight sealing properties, but the dissolved salt rock creates an irregularly shaped cavern.
Can a laboratory simulation simulate a cavern?
To address these limitations, this study presents a novel laboratory simulation device, which is capable of replicating the coupled thermo-mechanical (T-M) conditions of underground CAES caverns, including geostresses up to 100 MPa, temperatures up to 300 °C, and cyclic gas pressures of 0–70 MPa.
What are the advantages of compressed air energy storage?
Compressed air energy storage has the following advantages: site selection is relatively flexible, and energy storage systems can be built according to existing wind power or photovoltaic power plant sites. The storage efficiency is high, and its conversion efficiency can usually reach 70%–90%.
