Gravity energy storage system is an innovative energy storage concept based on the same principle as PHES. This system has attracted attention lately due to the many benefits it provides as it does not require any special geographical requirement [ 39 ].
This system stores electricity in the form of gravitational potential energy. This work presents an approach to size gravity storage technically and economically. It performs an economic analysis to determine the levelized cost of energy (LCOE) for this technology, and then compares it to other storage alternatives.
The results reveal that GES has resulted in good performance metrics including IRR and NPV of project and Equity, as well as ADSCR, and LLCR. In addition, for a 1 GW power capacity and 125 MWh energy capacity system, gravity energy storage has an attractive LCOS of 202 $/MWh.
This case study makes use of gravity energy storage which is considered suitable to be used in large scale applications. The technical and economic parameters of this storage system are used as inputs. The system operation and maintenance cost is equal to 0.4 €/kWh with a storage efficiency of 80% (Aneke and Wang, 2016).
Solid gravity energy storage systems may have transmission failures or control errors, and intelligent fault diagnosis systems, such as deep learning-based anomaly detection algorithms, can improve the reliability and safety of the system [38, 39]. 4.2.4.
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.
This study highlights the potential of GESS as a key component in future low-carbon power systems, offering both technical and economic advantages over traditional energy storage technologies.
