Storing Power With Falling Weight Systems

Engineers across the world are exploring ways to store renewable energy using gravity instead of chemicals. By lifting and lowering heavy weights, electrical energy can be converted into potential energy and recovered later when demand rises. From Energy Vault’s massive concrete block towers to Gravitricity’s deep shaft experiments, mechanical storage is proving efficient and durable. These systems work without rare materials, require little maintenance, and can last for decades. Gravity-based storage may soon become one of the most stable and sustainable solutions for large-scale clean power.
