Compressed Air Energy Storage Sample Clauses
Compressed Air Energy Storage. A compressed air energy storage (CAES) system stores energy in the form of air at high pressure (typically 50bar) that can be used to drive a gas turbine generator to produce electrical power. The basic system consists of a compressor used to charge or top up a high-pressure storage tank and a gas turbine driven generator, as shown in Figure 59.
