Technical FAQs 4

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.

Where can a compressed air energy storage facility be built?

Compressed Air Energy Storage (CAES) facilities can be built in locations that have suitable geological formations for storing compressed air. Ideal sites typically include underground caverns, such as salt domes, depleted natural gas fields, or aquifers, which can effectively contain the high-pressure air.

What is Siemens Energy compressed air energy storage?

Siemens Energy Compressed air energy storage (CAES) is a comprehensive, proven, grid-scale energy storage solution. We support projects from conceptual design through commercial operation and beyond.

Why should you use air as a storage medium?

The use of air as a storage medium is a significant strength, as it is readily available and easy to obtain, eliminating concerns related to resource scarcity. CAES systems can store energy for much longer periods compared to battery storage systems, making them particularly suitable for applications requiring extended energy supply.
