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

Green Car Congress

Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. 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. Slocum, A.H.;

To Store or Not to Store: That is the Question

Green Car Congress

“ Why do you need energy storage on the grid, when the grid is full of power plants that generate all the energy that is needed? Due to the inherent capital costs and characteristics of the leading alternative energy mediums: Hydro, Wind and Solar, Solar deployment has started to emerge as the leading candidate of choice.
