Gravitricity energy storage: is a type of energy storage system that has the potential to be used in HRES. It works by using the force of gravity to store and release energy. In this energy storage system, heavy weights are lifted up and down within a deep shaft, using excess electricity generated from renewable sources such as wind or solar.
