Air energy storage test successful

What is CAES (compressed air energy storage)?

Recently, a major breakthrough has been made in the field of research and development of the Compressed Air Energy Storage (CAES) system in China, which is the completion of integration test on the world-first 300MW expander of advanced CAES system marking the smooth transition from development to production.

How to reuse temperature related exergy of compressed air?

The simplest way to reuse the temperature related part of the exergy of the compressed air is to store the hot air itself inside a combined thermal energy and compressed air storage volume (Fig. 18 a). Due to the high temperatures already reached at rather low pressure ratios these concepts require highly temperature resistant storage volumes.

What is advanced compressed air energy storage (a-CAES)?

The Hydrostor facilities were said to use an updated version of the CAES technology called Advanced Compressed Air Energy Storage (A-CAES) that incorporates components from existing energy systems to produce an advanced, emissions-free storage system.

What are the advantages of compressed air energy storage technology?

Energy storage technologies have been viewed as a key supporting technology for the energy revolution and a national strategic emerging technology. Compressed air energy storage technology holds many advantages such as high capacity, low cost, high efficiency, and environmental friendliness.

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.

When was compressed air energy storage invented?

By then the patent application “Means for Storing Fluids for Power Generation” was submitted by F.W. Gay to the US Patent Office . However, until the late 1960s the development of compressed air energy storage (CAES) was pursued neither in science nor in industry.
