This concept is known as gravity storage, as it stores electricity in the form of gravitational potential energy. This storage option provides better operating characteristics and economically sounds solution over conventional pumped hydro storage, and can be placed almost anywhere electricity storage is needed.
Depending on the considered scenarios and assumptions, the levelized cost of storage of GES varies between 7.5 €ct/kWh and 15 €ct/kWh, while it is between 3.8 €ct/kWh and 7.3 €ct/kWh for gravity energy storage with wire hoisting system (GESH). The LCOS of GES and GESH were then compared to other energy storage systems.
Gravity energy storage is a physical method of storing energy that offers advantages such as system safety, flexibility in location, and environmental friendliness. In addition, it boasts a long lifespan, low cost, zero self-discharge rate, large energy storage capacity, and high discharge depth.
