6 FAQs about [Kw-class compressed air energy storage equipment]
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.
Is compressed air energy storage better than other power storage units?
As a large-scale power storage unit with specifications for long-term storage and extended continuation of discharge, the compressed-air energy storage plant can be superior to (less expensive than) other power storage units in terms of the ratio of plant cost to the amount of power (kWh) that can be stored, that is, the unit price of kWh.
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.
