Large-scale energy storage technology is crucial to maintaining a high-proportion renewable energy power system stability and addressing the energy crisis
Gravity Battery: A New Innovation for a Sustainable Energy Storage. June 2023. DOI: 10.1109/CEEGE58447.2023.10246686. Conference: 2023 6th International Conference on Electrical Engineering and
Solid gravity energy storage technology has excellent potential for development because of its large energy storage capacity, is hardly restricted by geographical conditions, and low cost. SGES is one of the ideal alternatives for wind power and photovoltaic energy storage in areas lacking PHES construction conditions.
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.
Energy storage capacity. To analyse the energy storage capacity, the potential energy of the piston can be stated as (1) E = mgh, where m is the mass in kg, g is the gravitational constant (9.81 m/s 2) and h is the height. Converting between Joule (J) and Watt-hour (Wh) is done as in (2). (2) 1 kWh = 3.6 × 10 6 J.
