Batteries are now being built at grid-scale in countries including the US, Australia and Germany. Thermal energy storage is predicted to triple in size by 2030. Mechanical energy storage harnesses motion or gravity to store electricity.
How is energy stored in a pond?
Energy is stored by pumping water from a surface pond under pressure into the pore spaces of underground rocks at depths of between 300 and 600 meters; electricity is generated by uncapping the well and letting the water gush to the surface and spin a turbine.
