Fig. 1 is a schematic diagram of a CAES plant, which is analogous to a natural gas generator in which the compression and expansion stages are separated by a storage stage. In a conventional gas plant, 55–70% of the electricity produced is used to compress air in preparation for combustion and expansion (Gyuk and Eckroad, 2003)
An alternative to this is compressed air energy storage (CAES). Compressed air energy storage systems have been around since the 1940s, but their potential was significantly studied in the 1960s
Compressed Air Energy StorageWhen off-peak power is available or additional load is needed on the grid for balancing, that excess power can be used to compress air and store i. in deep geologic reservoirs. When additional generation is needed, the stored high-pressure air is returned to the surf.
In this paper, a compressed-air energy storage (CAES) system integrated with a natural gas combined-cycle (NGCC) power plant is investigated where air is extracted from the gas turbine compressor or injected back
1. Introduction. The use of renewable energies such as wind and solar power continues to increase in many countries since greenhouse gas emissions from conventional power plants have resulted in severe environmental problems [1, 2].The wind power generation reached 3% (i.e. 435 GW) of global electricity production in 2015 and it

The application analysis reveals that battery energy storage is the most cost-effective choice for durations of <2 h, while thermal energy storage is competitive for durations of 2.3–8 h. Pumped hydro storage and compressed-air energy storage
Many energy storage technologies have been commercialised or are still under research. These include pumped hydro storage (PHS), compressed air energy storage (CAES), batteries, fuel cells
The potential energy of compressed air represents a multi-application source of power. Historically employed to drive certain manufacturing or transportation systems, it became a source of vehicle propulsion in the late 19th century. During the second half of the 20th century, significant efforts were directed towards harnessing

Adiabatic Compressed Air Energy Storage (A-CAES) was proposed to eliminate fossil fuel consumption and CO 2 emission [13], [14], [15]. The main difference between an A-CAES system and a conventional CAES system is that additional heat storage is released in a separate heat storage reservoir during the compression process.
Three energy storage systems are modelled and costed: Pumped Seawater Hydro Storage (PSHS), Compressed Air Energy Storage (CAES), and Thermal Energy Storage (TES). It is found that CAES is the most profitable storage medium, requiring a capital expenditure of A$140 M and generating a rate of return (ROR) of
To address the latter, compressed air energy storage with sub-sea caverns was investigated for the United Kingdom for very long-time storage (inter-seasonal) storage but the roundtrip energy efficiency of 54–59% and the requirement of such long-time storage resulted in a system that was too costly for practical use [12].
