5) Gravity-Based Energy Storage. Gravity-based energy storage systems use the potential energy of raised masses, such as heavy blocks or containers of materials, to store energy. During periods of excess energy generation, the mass is lifted. When energy is needed, the mass is lowered, and the potential energy is converted back into electricity.
