3.1.5 Compressed Air Storage. Compressed Air Energy Storage (CAES) is an option in which the pressure energy is stored by compressing a gas, generally air, into a high pressure reservoir. The compressed air is expanded into a turbine to derive mechanical energy and hence run an electrical generator.

World. Total carbon emissions. Although the performance of cooling equipment is continually improving and electricity production is becoming less carbon-intensive, indirect CO 2 emissions from space cooling are increasing rapidly, nearly tripling from 1990 to just over 1 Gt CO 2 in 2022. Emissions were more than 2% higher in 2022 than in 2021.
