How can large-scale power storage be realized?

In addition to PHS, compressed air energy storage (CAES) is another feasible way to realize large-scale power storage. Since 1949 when Stal Laval proposed to store compressed air using underground caverns, the research in CAES has been progressing.

How do compressed air energy storage systems work?

In compressed air energy storage systems, electricity runs a compressor on land to produce compressed air. During this process, waste heat is captured and can be used to increase the round-trip efficiency from about 60 percent to as high as 80 percent. The compressed air is then pressurized to match the pressure at the ocean floor where the balloons are located.

How do energy storage systems work?

As fluctuating renewables become increasingly prevalent, power systems will face the situation where more electricity is produced than it is needed to cover the demand. The solution: Effective energy storage systems store this excess energy, allowing operators to draw on it as needed.
