This paper proposes a new storage concept called Mountain Gravity Energy Storage (MGES) that could fill this gap in storage services. MGES systems move sand or gravel from a lower storage site to an upper elevation.
Hunt and his collaborators have devised a novel system to complement lithium-ion battery use for energy storage over the long run: Mountain Gravity Energy Storage, or MGES for short.
This study aims to introduce slope gravity energy storage principles and structures, specifically focusing on installations based on mountain slopes and inclined mines.

A case study at Al Hada Mountain, Al Taif, Saudi Arabia, demonstrates the integration of OVF2R-MGESS with a grid-connected solar PV system, taking advantage of the region''s high solar irradiance and elevated mountainous terrains.
MGES uses natural elevation changes to store and release energy efficiently and sustainably. How it works: Large masses (like railcars) are moved up a mountain during times of excess energy, then released downhill to generate power during periods of high demand.
This paper argues that this gap can be filled with a novel solution called Mountain Gravity Energy Storage (MGES). MGES is an EES technology that deploys an electric motor for lifting a solid mass to a high elevation in the charging mode and releasing that mass to rotate the electricity generator whenever needed (i.e., discharging).
One researcher proposes using a scheme called a Mountain Gravity Energy Storage (MGES) as a solution. Illustration: IIASA The system is very flexible, says Hunt, because you can easily alter the speed of the cables, increase the load, or change the number of vessels to meet varying energy demands.
Conclusion This paper concludes that mountain gravitation energy storage could be a viable alternative to long-term energy storage, particularly, in isolated micro-grids or small islands demanding storage capacities lower than 20 MW.
A team of European scientists proposes using mountains to build a new type of battery for long-term energy storage. The intermittent nature of energy sources such as solar and wind has made it difficult to incorporate them into grids, which require a steady power supply.
In ESS gravity energy storage systems (GESS) are more advantageous in terms of siting, scale and economics compared to battery energy storage systems (BESS) and compressed air energy storage (CAES) .
Based on the characteristics of gravity energy storage system, the paper presents a time division and piece wise control strategy, in which, gravity energy storage system occupies a dominant position supplemented by vanadium redox batter.
