Preparation of Compressed Air Energy Storage Demonstration Project Proposal

What is compressed air energy storage (CAES)?

Compressed Air Energy Storage (CAES) is a technology that stores excess energy by compressing air in underground caverns. During periods of high energy demand, the stored air is released to generate electricity. This method is advantageous for balancing energy supply and demand.

What is an example of a widespread storage technology deployment?

One example they mention is precisely CAES. The IEA Technology Roadmap states that the key to achieving widespread storage technology deployment is enabling compensation for multiple services delivered across the energy system.

How many mw can a compressed air system produce?

CAES systems are categorized into large-scale compressed air ES systems and small-scale CAES. Large-scale systems are capable of producing >100 MW, while the small-scale systems only produce 10 MW or less . Moreover, the reservoirs for large-scale CAES are underground geological formations such as salt formations, host rocks and porous media.

How are CAES projects data organized?

Detailed CAES projects data from the U.S.A., Canada, and Europe were organized into large or small-scale projects in five tables (as Supplementary material), according to their category: a) general data (Table A.1); b) technical data (Table A.2); c) reservoir data (Table A.3); d) economic data (Table A.4) and e) project status (Table A.5).
