With renewable energy increasingly being located at sea, its worth asking what offshore energy storage systems could be used alongside the wind farms and tidal and wave arrays. Photo credit: MIT

The renewable energy storage concept announced by the Massachusetts Institute of Technology (MIT) earlier this year is quite literally a load of balls. Aimed at storing excess power from offshore wind farms, says MIT: “The key to this concept is the placement of huge concrete spheres on the seafloor under the turbines.
