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.
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.
Gravity energy storage (GES) is one of those innovative storage technologies that is still under development. Hence, this study proposes a new methodology which aims to optimally design and deploy a large-scale GES system in a hybrid PV-Wind plant to make it more competitive technically and economically.
3. Optimal sizing model of gravity energy storage GES is a hydro-mechanical energy storage system which stores energy in gravitational potential form. Therefore, this study aims to determine the optimal size of GES components to ensure a required robustness while minimizing the cost of the whole system.
This paper conducts a comparative analysis of four primary gravity energy storage forms in terms of technical principles, application practices, and potentials. These forms include Tower Gravity Energy Storage (TGES), Mountain Gravity Energy Storage (MGES), Advanced Rail Energy Storage (ARES), and Shaft Gravity Energy Storage (SGES).
