Supercritical Compressed Air Energy Storage Power Station

What is a supercritical compressed air energy storage system?

A novel supercritical compressed air energy storage system is proposed. The energy density of SC-CAES is approximately 18 times larger than that of conventional CAES. The characteristic of thermodynamics and exergy destruction is comprehensively analysed.

What is the largest compressed air energy storage power station in the world?

The power station, with a 300MW system, is claimed to be the largest compressed air energy storage power station in the world, with highest efficiency and lowest unit cost as well.

What is a compressed air energy storage station?

"The compressed-air energy storage station offers large capacity, long storage time (over 4 hours), and efficient response, making it comparable to small and medium-sized pumped storage power plants," Liu Yong, Secretary General of Energy Storage Application Branch of China Industrial Association of Power Sources told the Global Times on Wednesday.

What are the transient characteristics of compressed air energy storage systems?

Transient characteristics with control under parameter steps are explored in depth. Both volume effect and thermal inertia are considered for system dynamic study. Compressed air energy storage systems are often in off-design and unsteady operation under the influence of external factors.

How is supercritical air cooled?

The supercritical air is cooled to liquid state by the stored cold energy in the cold storage/heat exchanger and then expanded to atmospheric pressure using the valve or liquid expander.
