Global Compressed Air Energy Storage (CAES) Market - Growth, Trends, and Forecast (Outlook to 2028)

The global compressed air energy storage (CAES) market growth is driven by implementing onshore and offshore renewable energy sources (MW-GW) demonstrating projects. These, coupled with technological developments in the compressed air energy storage systems (adiabatic systems), are expected to drive the market.

Increasing the use of energy storage technologies in T&D because a small amount of energy storage can delay or avoid a costly T&D upgrade is called T&D deferral.

A compressed air energy storage system can support the normal operations as a peak load supplier, frequency regulation, contingency services, and black start.

The market for air-compressed systems is still undeveloped due to the lack of investment, technology, and competition from other energy storage technologies affecting the compressed air energy storage (CAES) market.

Compressed air energy storage (CAES) is a way to store massive amounts of renewable power (MW-GW) by compressing air at very high pressures and storing it in large underground caverns, depleted wells, or aquifers. The compressed air can be released and run through turbines to generate power when wind turbines and solar plants reduce output and necessary power.

Benefits of compressed air energy storage (CAES):

• It offers a long cycle of life or lifetime (approx 30 years).
• The supply will be continuous for 36 to 48 hours.
• Low self-discharge

Operational necessities of Compressed Air Energy Storage System:

• There are clutches on both ends of the motor/generator (to engage or disengage the compressor and expander train ).
• Compressors with multiple stages and intercoolers to reduce the power requirements during the compression cycle, and aftercoolers to reduce the storage capacity requirements.
• Expander train with high and low pressure turboexpanders with combustors between stages.
• To regulate and control the off-peak energy storage and peak power supply, switch from the compressed air storage mode to the electric power generation mode, or operate the plant as a synchronous condenser to regulate VARS on the grid).
• Auxiliary equipment (fuel storage and handling, cooling, mechanical, electrical, and heat exchangers).
• Underground or aboveground compressed air storage, including piping and fittings. Underground storage is often performed in aquifers or mined caverns, while aboveground air storage is executed within specially designed holding tanks.

During the forecast period, the Adiabatic CAES system will remain the leading type among the various CAES types.

Demand for CAES from the USA, China, Japan, and Europe is robust due to the increase in T&D deferral systems.

The global compressed air energy storage (CAES) market comprises sales of compressed air energy storage operational necessities and EPC for power transmission and distribution, industrial applications, construction, and agriculture.

Some of the Opportunities:

• There is a growing need for long-duration energy storage to enable the low carbon energy transition.
• Non-reversible grid trends, including aging and up-gradation of power infrastructure and the variability introduced by growing penetrations of renewable energy.
• Markets with growth potential are North America, France, Spain, China.

Some of the Restraints:

• Only a few R&D institutes worldwide specialize in CAES research and its applications.
• Storage capacity and fixed costs are inversely proportional to each other.
• High costs of operation and installation.

Some of the Drivers:

• Low Cost, Long life
• Ability to site where needed
• Customized system design
• Ancillary services
