How much does isothermal deep ocean compressed air energy storage cost?
Herein, we introduce an innovative energy storage proposal based on isothermal air compression/decompression and storage of the compressed air in the deep sea. Isothermal deep ocean compressed air energy storage (IDO-CAES) is estimated to cost from to USD/kW for installed capacity and 1 to 10 USD/kWh for energy storage.
What are ocean energy storage systems?
Ocean energy storage systems use the natural properties of the ocean for energy storage. They are not-so-distant cousins to pumped hydro (PHS) and compressed air energy storage (CAES) systems on land. There are two main types of ocean energy storage: underwater compressed air energy storage (UCAES) and underwater pumped hydro storage (UPHS).
What is underwater compressed air storage?
A similar energy storage proposal that has been receiving substantial attention is underwater compressed air storage. It consists of a fixed storage site on the deep sea and a compressor that sends pressurized air to the storage site .
How does a seawater storage system work?
The system stores energy by pumping superficial seawater into the isothermal air compressor. The compressed air flows to the deep sea storage tanks, where it replaces the seawater inside the tanks.
How does a compressed air energy storage system work?
In an underwater compressed air energy storage (UCAES) system air at pressure is stored inside large pliable bags on the seafloor. Below certain depths, the weight of the water column provides the required pressure to contain the pressurized air inside the bags, preventing them from popping like a balloon.
What is compressed air energy storage (CAES)?
Compressed air energy storage (CAES) is a utility-scale electricity storage solution with a few operational plants today [ 16 ]. While the turbomachinery part of the technology is based on commercial, mature technologies, CAES has not received attention due to a few challenges.
