Ocean energy storage is a broad category of a whole heap of different methods of generating and/or storing energy in the open ocean. It’s an area that has recently experienced a huge surge of interest, with probably dozens of new startups in the space in recent years, mostly still at very low technology maturity.

The companies that I’ve seen developing ocean energy storage systems pretty much all use one of three operating principles: pumped hydro, gravity and buoyancy.

In this video I'll talk about how each of these energy storage principles works, and mention some of the companies who are trying to commercialise each type of ocean energy storage.
