Compressed-air-energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational as of.

Carbon storage involves injecting carbon dioxide into suitable geological formations at depth of 800 meters or more for permanent isolation. Geological energy storage, on the other hand, involves compressing air or other gases using surplus electricity during off-peak hours and temporarily storing them in underground reservoirs.
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.

2.1 Fundamental principle. CAES is an energy storage technology based on gas turbine technology, which uses electricity to compress air and stores the high-pressure air in storage reservoir by means of underground salt cavern, underground mine, expired wells, or gas chamber during energy storage period, and releases the compressed air to drive turbine to
Also, it would introduce a generalized form of compressed gas energy storage (CGES), which would rely on another gas (CO 2, for example) to be the working fluid instead of air in a closed-loop cycle. It should be mentioned that the energy density of compressed-air systems is lower than that of combustion-based processes, and losses due to airflow are particularly
In recent years, engineers'' eyes have been increasingly captured by the compressed CO 2 energy storage since it is a competitive electricity storage technology equipped with massive renewable power plants.

As renewable energy production is intermittent, its application creates uncertainty in the level of supply. As a result, integrating an energy storage system (ESS) into renewable energy systems could be an effective
To the time being, air and CO 2 are the most used working and energy storage medium in compressed gas energy storage [3], [4].For instance, Razmi et al.

Another idea is compressed air energy storage (CAES) that stores energy by pressurizing air into special containers or reservoirs during low demand/high supply cycles, and expanding it in air turbines coupled with electrical generators when the demand peaks The storage cavern can also requires availability be a suitable geographical site such as a depleted
This paper introduces, describes, and compares the energy storage technologies of Compressed Air Energy Storage (CAES) and Liquid Air Energy Storage (LAES).

Global energy storage demands are rising sharply, making the development of sustainable and efficient technologies critical. Compressed carbon dioxide energy storage (CCES) addresses this imperative by utilizing CO2, a major greenhouse gas, thus contributing directly to climate change mitigation.
We presented a new technology for large-scale energy storage by compressing natural gas and injecting it into depleted hydraulically fractured wells and releasing the pressurized gas through an expander as a daily energy arbitrage and/or seasonal energy storage solution. We developed three models to account for the thermodynamic state of the
With pressurized air, the turbine generates electricity using significantly less natural gas. Compressed air energy storage is also suitable for load leveling because it can be developed in capacities of a few hundred MWs and can be discharged over long (4–24 h) periods of time.

In 2015, a novel compressed gas energy storage prototype system was developed at Oak Ridge National Laboratory. In this paper, a near-isothermal modification to the system is proposed. In common with compressed air energy storage, the novel storage technology described in this paper is based on air compression/expansion. However, several
Compressed-air energy storage can also be employed on a smaller scale, such as exploited by air cars and air-driven locomotives, and can use high-strength (e.g., carbon-fiber) air-storage tanks.
Therefore, the electrical energy stored in a single gas storage chamber represents the energy storage density of a compressed gas energy storage system:92
The proposed compressed gas energy storage system will produce electricity upon withdrawal of the high-pressure gas that was previously injected by the electric-drive compressors. The CGES system also includes an aero-derivative gas turbine for a nameplate rating of 35 MWe with a primary energy efficiency of 42.4 percent.

To improve the output electric energy of a compressed gas energy storage system, an additional component of thermal energy is normally provided to heat the high-pressure gas entering the expansion turbine during the energy release phase, to boost the turbine's output work.
As a new type of electric energy storage system, the compressed carbon dioxide energy storage system has a long construction period and an operating income period of more than ten years to several decades, which prolongs the project's break-even period and does not have obvious economic benefits in the short term.
