Solid gravity energy storage technology (SGES) is a promising mechanical energy storage technology suitable for large-scale applications. However, no systematic summary of this technology research and application progress has been seen.
The decision tree is made for different technical route selections to facilitate engineering applications. Moreover, this paper also proposed the evaluation method of large-scale energy storage technology and conducted a comparative analysis of solid gravity energy storage with other large-scale energy storage technologies.
Abstract: With the grid-connected ratio of renewable energy growing up, the development of energy storage technology has received widespread attention. Gravity energy storage, as one of the new physical energy storage technologies, has outstanding strengths in environmental protection and economy.
In conclusion, solid gravity energy storage systems are emerging alternatives to pumped hydro energy storage systems. They have the means to address issues related to geographical adaptability and scalability. In the recent years, there has a surging interest in studying and building these systems.
Although effective, a primary concern of PHES is the geographical constraint of water and longer term scalability. In this report, I will introduce solid gravity energy storage as an emerging alternative GES and explore a few primary systems.
