MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

The key to this Ocean Renewable Energy Storage (ORES) system is the placement of 30-meter-diameter hollow concrete spheres on the seafloor under the wind turbines. These structures would serve both as anchors to moor the floating turbines and as a means of storing the energy they produce. Earlier post.). Slocum, A.H.;
