It is a known fact that renewables suffer from intermittency. This causes fluctuating energy generation which forces grid operators to encounter the problem of unbalanced power and frequency disturbances. Energy storage is always necessary if a high percentage of renewable energy sources are used. Therefore, the current study is quite significant as it introduces a new large-scale storage technique that happens to be sustainable in many ways and also encouraging as it forms an impressive combination of utility-scale renewable energy generation and energy storage. The ability to store power on a large scale will be an essential feature of any sustainable and reliable energy system. This can be accomplished by storing the energy in a local storage system with sufficient capacity. The Hydraulic Rock energy storage system is the solution to this ambitious level of self-sufficiency as it relies primarily on local resources and has an efficiency of over 80%.
