Carry out research and development of compressed air energy storage

What is compressed air energy storage (CAES)?

Among all the ES technologies, Compressed Air Energy Storage (CAES) has demonstrated its unique merit in terms of scale, sustainability, low maintenance and long life time. The paper is to provide an overview of the current research trends in CAES and also update the technology development.

How can compressed air energy storage improve the stability of China's power grid?

The intermittent nature of renewable energy poses challenges to the stability of the existing power grid. Compressed Air Energy Storage (CAES) that stores energy in the form of high-pressure air has the potential to deal with the unstable supply of renewable energy at large scale in China.

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.

Is there a future for compressed air storage?

There are two large scale compressed air storage plants are in operation and their success encourages the technology development. A number of pilot projects in building new generation of CAES are on-going. All the projects have demonstrated the difficulties in financial investment.

What is energy storage & why is it important?

Energy storage (ES) plays a key role in the energy transition to low-carbon economies due to the rising use of intermittent renewable energy in electrical grids. Among the different ES technologies, compressed air energy storage (CAES) can store tens to hundreds of MW of power capacity for long-term applications and utility-scale.

Which energy storage technology is most suitable for large-scale energy storage?

Among the available energy storage technologies, Compressed Air Energy Storage (CAES) has proved to be the most suitable technology for large-scale energy storage, in addition to PHES .
