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).
The Energy Storage System (ESS) for marine or sea vehicles is a combination of dissimilar energy storage technologies that have different characteristics with regard to energy capacity, cycle life, charging and discharging rates, energy and power density, response rate, shelf life, and so on.
There is also the Stored Energy in the Sea (StEnSEA) project that is being supported by a consortium of German companies, which is also in the process of a small-scale pilot project over the next couple of years. In an underwater compressed air energy storage (UCAES) system air at pressure is stored inside large pliable bags on the seafloor.

The paper shows that deep ocean gravitational energy storage technologies are particularly interesting for storing energy for offshore wind power, on coasts and islands without mountains, and as an effective approach for compressing hydrogen.
The use of seawater batteries exceeds the application for energy storage. The electrochemical immobilization of ions intrinsic to the operation of seawater batteries is also an effective mechanism for direct seawater desalination.
