The proposed gravity-based storage system is considered ideal for residential PV systems located in regions with high solar radiation. A British-Nigerian research team has developed a model to design PV systems coupled to gravity-based energy storage systems.
The utilization of the gravity to store energy of any form is an idea in its infant stage [ 4 ]. Study shows that the pumped hydroelectric storage system (PHES) still remains the current most harnessed form of storage in the world on a long term and on a large scale [ 5 ].
High capacity: Gravity energy storage systems have the ability to store large amounts of energy, making them ideal for grid-scale energy storage. Scalability: Gravity energy storage systems can be scaled up or down depending on the energy storage requirements.
Furthermore, Thomas Morstyn et al., developed the design of Gravity energy storage using suspended weights for abandoned mine shafts. Energy is stored in this system by delivering current from the electrical network to raise the suspended weights along the rail set up in the system.
Some of the aforementioned researches includes pumped hydro gravity storage system, Compressed air gravity storage system, suspended weight in abandoned mine shaft, dynamic modelling of gravity energy storage coupled with a PV energy plant and deep ocean gravity energy storage.
A typical hydro system that rely on gravity to store energy is the dynamic modelling of gravity energy storage coupled with a PV energy plant work by Asmae Berrada et al. The aim of his model is to investigate gravity effect on energy storage.
