Pumped hydro makes up 152 GW or 96% of worldwide energy storage capacity operating today. Of the remaining 4% of capacity, the largest technology shares are molten salt (33%) and lithium-ion batteries (25%). Flywheels and Compressed Air Energy Storage also make up a large part of the market.
Supplementary combustion compressed air energy storage (SC-CAES) is the earliest developed CAES technology, represented by the Huntorf Power Station (1978) and McIntosh Power Station (1991) [13]. In SC-CAES, the compression heat is not recovered during the compression process, and natural gas combustion is required in
In contrast to compressed air energy storage, the compressed steam coupling system described in this article necessitates a smaller capacity of water storage tanks. Specifically, a 1300m3 water storage tank is sufficient to support uninterrupted deep peak regulation of a 200 MW unit for a duration of 8.58 h.
CAES has a high energy capacity and power rating, making it appropriate to use as a stationary and large-scale energy storage due to its ability to store a large amount of energy. However, CAES''s energy and power density are low [ 25 ], which means that the amount of energy and power stored in a specific volume related to

1.1. Compressed air energy storage concept. CAES, a long-duration energy storage technology, is a key technology that can eliminate the intermittence and fluctuation in renewable energy systems used for generating electric power, which is expected to accelerate renewable energy penetration [7], [11], [12], [13], [14].
Currently, there are only two CAES power stations in commercial operation in the world, namely, the Huntor power station built in Germany and the Mcintosh power station built in America [11]. The two stations were built and put into use in the last century, and both use natural gas to make up for the combustion to boost the system''s power output.

Conceptual design studies have been conducted to identify Compressed Air Energy Storage (CAES) systems which are technically feasible and potentially attractive for future electric utility load-levelling applications. The CAES concept consists of compressing air during off-peak periods and storing it in underground facilities for later use.
The random nature of wind energy is an important reason for the low energy utilization rate of wind farms. The use of a compressed air energy storage system (CAES) can help reduce the random characteristics of wind power generation while also increasing the utilization rate of wind energy.
