A new system being developed at MIT would store excess energy in concrete spheres on the sea floor
The intermittent nature of wind and solar power generation is one of the biggest challenges facing these renewable energy sources. But this isn’t likely to remain a problem for much longer with everything from flywheels to liquid air systems being developed to provide a cheaper form of energy storage than batteries for times when the wind is blowing or the sun isn’t shining. A new concept out of MIT can now be added to the the list of potential solutions. Aimed specifically at offshore wind turbines, the concept would see energy stored in huge concrete spheres that would sit on the seafloor and also function as anchors for the turbines.
