What is compressed air energy storage (CAES)?

Compressed air energy storage (CAES) systems offer significant potential as large-scale physical energy storage technologies. Given the increasing global emphasis on carbon reduction strategies and the rapid growth of renewable energy sources, CAES has garnered considerable attention.

How do compressed air storage systems use energy?

The modeled compressed air storage systems use both electrical energy (to compress air and possibly to generate hydrogen) and heating energy provided by natural gas (only conventional CAES). We use three metrics to compare their energy use: heat rate, work ratio, and roundtrip exergy efficiency (storage efficiency).

Where will compressed air be stored?

In a Compressed Air Energy Storage system, the compressed air is stored in an underground aquifer. Wind energy is used to compress the air, along with available off-peak power. The plant configuration is for 200MW of CAES generating capacity, with 100MW of wind energy.

How is energy stored in a low demand space?

In low demand periods, energy is stored by compressing air in an air tight space (typically 4.0~8.0 MPa) such as an underground storage cavern. To store energy, air is compressed and sealed in the space. To extract the stored energy, compressed air is drawn from the storage vessel, mixed with fuel, and then combusted. The expanded air is then passed through a turbine.

What is a conventional compressed air energy storage system?

Schematic of a generic conventional compressed air energy storage (CAES) system. The prospects for the conventional CAES technology are poor in low-carbon grids [2,6–8]. Fossil fuel (typically natural gas) combustion is needed to provide heat to prevent freezing of the moisture present in the expanding air .

Can compressed air store electricity at scale?

One of the critiques of using compressed air to store electricity at scale is its low exergy density. Here, we define exergy density of the storage facility as the ratio of the delivered exergy (i.e., expansion work) to the volume of the air storage cavern.
