Compressed air energy storage environmental assessment public announcement time

What are the environmental impacts of compressed air energy storage?

We model life cycle environmental impacts for compressed air energy storage. Both conventional (CAES) and adiabatic (ACAES) storage options are investigated. Addition of air storage to wind power generation increases impacts moderately. Main impact due to natural gas combustion (CAES) or thermal energy storage (ACAES).

What is compressed air energy storage?

Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.

What are the different types of compressed air energy storage (CAES)?

Figure 1. Various options for compressed air energy storage (CAES). PA-CAES: Porous Aquifer-CAES, DR -CAES: Depleted Reservoir CAES, CW-CAES: Cased Wellbore-CAES. Note: this figure is not scaled. Figure 2. A sealed mine adit as a potential pressure vessel. Note - CA: compressed air, RC: reinforced

What impact does acaes have on the environment?

As a large part of the impacts for ACAES is related to the material intensive thermal energy storage system, which in turn scales with the air storage capacity, there is a significant trade-off between environmental impacts per unit production and the technological possibility to maximize wind baseload power generation.

Can a small compressed air energy storage system integrate with a renewable power plant?

Assessment of design and operating parameters for a small compressed air energy storage system integrated with a stand-alone renewable power plant. Journal of Energy Storage 4, 135-144. energy storage technology cost and performance asse ssment. Energy, 2020. (2019). Inter-seasonal compressed-air energy storage using saline aquifers.

Should compressed air be injected into a depleted oil & gas reservoir?

However, care is required to inject compressed air into depleted oil and gas reservoirs due to the potential for a combustible environment at the surface or in the subsurface (Kim et al., 2023). CAES also offers extended energy storage durations, enabling the storage of electricity for prolonged periods.
