The capital expenditures of the gravity energy storage systems are very high, while the percentage of the round-trip efficiency of mechanical systems can vary from low to 90% for some applications e.g. the "Energy Vault Tower". The economic feasibility of constructing gravity storage systems depends on the widespread of its applications [15].

The Switzerland and California-based company announced that it is entering the first phases of commissioning for its first commercial-scale gravity energy storage system (GESS). Slated to be fully grid-interconnected in Q4 2023, the gravity tower will mark the world''s first non-pumped hydro gravity-based storage facility.
Abstract: Despite the fact that renewable energy resources play a significant role in dealing with the global warming and in achieving carbon neutrality, they cannot be effectively used until they combine with a suitable energy storage technology. Gravity batteries are viewed as promising and sustainable energy storage, they are clean, free, easy accessible,
The ramp rate for Energy Vault''s gravity storage solution is as little as one millisecond, and the storage system can go from zero to 100% power in no more than 2.9 seconds. Furthermore, the system has round-trip power efficiency, i.e. zero to full power to zero, of 90% efficiency, meaning only 10% energy loss.
In Ref.

Gravity energy storage systems operate using similar principles as pumped hydro storage, which is currently the largest source of grid storage. GESS installations use surplus energy to lift heavy blocks, which creates potential energy that can later be converted into electricity when lowered to the ground. Unlike pumped hydro storage facilities
