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).
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 obtained results demonstrate that gravity storage provide sound operating and economic characteristics compared to other storage technologies. 1. Introduction
The review shows that pumped hydro energy storage (PHES) has reached a high maturity level as a technical system and is well covered by economic evaluation methods, whereas solid gravity energy storage (SGES) is still in an initial stage for system design and assessment.
The efficiency of the system is approximately 80% as claimed by developers (Aneke and Wang, 2016). A sketch of this technology is presented in Fig. 1. Gravity energy storage consists of a container filled with a fluid (water) and a heavy piston. The container is linked to a return pipe which allows the flow of water.
Economic analysis is performed. Gravity energy storage delivers a low LCOE. High share of intermittent renewable energy sources disrupts the reliability and the proper operation of the electric grid. Power systems are now on the starting point of a new transformation where high cost requirements have been imposed to secure the supply of energy.

Additionally, this study examines China's current state of energy storage technology based on authorized patents and explores its future development trends across electric energy storage systems (EESS), mechanical energy storage systems (MESS), chemical energy storage systems (CESS), thermal energy storage systems (TESS), and hydrogen-based energy storage systems (HESS).

China is gradually forming an open electricity sales market with diversified competitors. With ancillary services as the main base, the two-part tariff business model is used for electricity price incentives. Due to its flexibility, energy storage should be widely used in competitive models.
However, China's energy storage is developing rapidly. The government requires that some new units must be equipped with energy storage systems. The concept of shared energy storage has been applied in China, which effectively promotes the development of energy storage. 4.3. Explore new models of energy storage development
“The Energy Development Strategic Action Plan (2014∼2020)”, “Made in China 2025”, “Guiding Opinions on Smart Grid Development” and other documents have made plans for China's energy development, they emphasize that the development of energy storage and its application scenarios have become the key goal of system reform .
In October 2017, China's first guiding policy for developing large-scale energy storage technology and applications “Guiding Opinions on Promoting the Development of Energy Storage Industry and Technology” was officially released.
It also introduces the application scenarios of energy storage on the power generation side, transmission and distribution side, user side and microgrid of the power system in detail. Section 3 introduces six business models of energy storage in China and analyzes their practical applications.
In China, generation-side and grid-side energy storage dominate, making up 97% of newly deployed energy storage capacity in 2023.
