Compressed air energy storage (CAES) plants are largely equivalent to pumped-hydro power plants in terms of their applications. But, instead of pumping water from a lower to an upper pond during periods of excess power, in a CAES plant, ambient air or another gas is compressed and stored under pressure in an underground cavern or container.
Compressed air has the ability to store large amounts of energy in a relatively small space, making it an efficient and compact solution for energy storage [10, 11].
What is Compressed Air Energy Storage? Compressed Air Energy Storage, or CAES, is essentially a form of energy storage technology. Ambient air is compressed and stored under pressure in underground caverns using surplus or off-peak power.
