where m i is the mass of the i th object in kg, h i is its height in m, and g = 9.81 m/s 2 is the acceleration due to gravity.. As of 2022, 90.3% of the world energy storage capacity is pumped hydro energy storage (PHES). [1] Although effective, a primary concern of PHES is the geographical constraint of water and longer term scalability.
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. Proceedings of OSES 2016 Offshore Energy and Storage Symposium
