Compressed Air Energy Storage (CAES) is an emerging mechanical energy storage technology with great promise in supporting renewable energy development and
CAES (Compressed air energy storage) system is a potential method for energy storage especially in large scale, with the high reliability and relative low specific investment cost , . Conventional CAES systems originate from the basic gas turbine technology.
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).
When storing renewable energy, compressed air energy storage (CAES) is a better choice. Compared with pumped energy storage, it is much less restricted by geographical location and has less damage to the ecological environment . CAES is divided into land-based and underwater types, among which land-based one is a relatively mature technology.
Once the stored compressed air is needed, the underwater compressed air flexible bag energy storage device will deliver the low-temperature and high-pressure compressed gas to the power generation system on the barge, and the low-temperature and high-pressure compressed air will enter the heat exchanger that stores heat.
The heat exchanger then heats the compressed air, and finally the high-temperature and high-pressure compressed air enters the turbine, making the turbine rotate at a high speed, and the turbine is connected to the generator to generate electricity, which is the working process of the whole adiabatic compressed air energy storage system.
From the above review, the energy release process of underwater compressed air flexible airbag energy storage is approximately isobaric due to the action of water pressure, which is more efficient and has greater energy storage capacity than the current land-based CAES system, and has greater development potential.
