Technical FAQs 4

How does a CAES power generation facility work?

A CAES power generation facility uses electric motor-driven compressors to inject air into an underground storage cavern and later releases the compressed air to turn turbines and generate electricity back onto the grid.

How does a CAES system store energy?

Conventional CAES systems store energy by driving large electric motors that pump compressed air into a mine. This process is done during off-peak energy demand when it is much less expensive. In addition, during the compression process the air is cooled down before injection in order to accommodate more air in the same space.

What does CAES stand for?

The compressed air energy storage project (CAES) project in Hubei, China. Image: China Energy Construction Digital Group and State Grid Hubei Integrated Energy Services. A compressed air energy storage (CAES) project in Hubei, China, has come online, with 300MW/1,500MWh of capacity.

What is compressed air energy storage (CAES)?

In Compressed Air Energy Storage (CAES), the clever management of thermal energy is the wit behind the solution, as it plays a crucial role in the system’s efficiency and overall performance. During the compression process, air is compressed and heated due to the increase in pressure.
