Abstract

In isolated or weakly connected power systems, the maximum exploitation of renewable intermittent energy sources can be obtained by means of cost-effective storage technologies. In this paper hydroelectric gravity storage is extended to the deep ocean context. A sturdy cavity full of water is submerged at great depth and the hydraulic work carried out when emptying it and recovered when filling it, constitutes the storage system. The possibility of using this technique, named DOGES: Deep Ocean Gravitational Energy Storage, as well as its costs and technical aspects are discussed. Atolls and oil platforms supplied with floating Photovoltaic (PV) or wind systems connected to DOGES are also discussed.
