Gravity Storage System Using Earth Materials (EarthPumpStore) Nottingham, United Kingdom, May 19 Academics have patented new concepts on electric power energy storage using gravity The concepts are being promoted by University ofGravity Energy Storage provides a comprehensive analysis of a novel energy storage system that is based on the working principle of wellestablished, pumped hydro energy storage, but that also recognizes the differences and benefits of the new gravity systemPumped Hydro Gravity Energy Storage Energy is used to raise a mass through a height thus storing energy as gravitational potential energy The amount of energy stored is mass times gravitational acceleration times height raised The most common large scale use of gravity energy storage in current use is pumped hydro storage, shown in the diagram Kinetic And Potential Energy Energy Conversions Gravitational energy storage well
