Ocean Battery stores renewable energy at the bottom of the sea

• New Atlas

Developed by Dutch startup Ocean Grazer, the Ocean Battery is designed to be installed on the seafloor near offshore renewable energy generators, like wind turbines, floating solar farms, tidal and wave energy systems. It is made up of three components that together function on a principle similar to that of a hydro dam.
