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.
How can compressed air energy storage improve the stability of China's power grid?
The intermittent nature of renewable energy poses challenges to the stability of the existing power grid. Compressed Air Energy Storage (CAES) that stores energy in the form of high-pressure air has the potential to deal with the unstable supply of renewable energy at large scale in China.
Is underground air storage a viable energy storage option?
Underground air storage is a large-scale energy storage option with relatively low cost (Table 3). The two existing commercial CAES plants, the Huntorf plant the McIntosh plant, both use underground salt cavern for energy storage.
How much does a CAES power station cost?
For a CAES capital cost of 700 $/kW, the lower limit of the electricity price difference becomes 0.04 $/kWh. Moreover, when the capacity cost of CAES is reduced to 400 $/kW, it is economically feasible to construct CAES power station in the most electricity-importing regions of China.
Does Kansas have a compressed air energy storage Act?
For example, the state of Kansas has facilitated these processes with their Compressed Air Energy Storage Act , effective since 2009.
