They can be summarized into two aspects: principle and equipment. As for the principle, although each technological route lifts heavy objects in different ways (e.g., using ropes, carriers, or water currents), they all do so by lifting heavy objects to store electrical energy. This is the reason why they are all called solid gravity energy storage.
