SGES includes tower-based, rail-based, and shaft-based gravity storage systems. These innovative approaches aim to expand the application scenarios of energy storage systems and enhance energy utilization efficiency. The second part focuses on liquid gravity energy storage. The third part describes solid gravity energy storage.
Among the prominent types of mechanical energy storage are Pumped Hydroelectric Energy Storage (PHES), Compressed Air Energy Storage (CAES), Flywheel Energy Storage (FES), and Gravity Energy Storage (GES).
The wet energy storage contains specific types of storage technology such as PHES (Pumped Hydroelectricity Energy Storage), GPM (Gravity Power Module), HHS (Hydraulic Hydro Storage) / GBES (Ground-Breaking Energy Storage), and UOSS (Underwater Ocean Storage Systems).
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).
Gravity energy storage (GES) technology relies on the vertical movement of heavy objects in the gravity field to store or release potential energy which can be easily coupled to electricity conversion. GES can be matched with renewable energy such as photovoltaic and wind power.
PGES has low material costs and high efficiency, but has a complex control system that requires high maintenance and poor suitability for large-scale deployment. Table 1. Practical characteristics of gravitational energy storage technologies. Mature, efficient, long-lasting. Requires specific terrain, high costs, environmental impact.
