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].
Pumped hydro, discussed in more detail elsewhere in this publication, also uses gravity as the motive force. In this case water stored at a high level can be discharged through a turbine at a lower level when energy is needed and the turbine may be reversed and used to pump water back to a high level when surplus electricity is available (or
