The Storage Potential of Gravity Wells
An excerpt from our white paper on the storage potential of gravity wells.
As the penetration of variable renewable energy resources increases in the United States, the availability of energy storage becomes more important to maintain grid reliability. Gravity energy storage is a mechanical storage technology that accumulates and releases energy due to an object’s change in height, otherwise known as vertical displacement. Pumped hydro storage is the most popular gravity storage technology yet it requires very specific geographies. This white paper explores the potential for using the massive depth and relative abundance of inactive oil and gas wells for gravity storage–thus converting them into “gravity wells”–and the feasibility of using such technology for large-scale electricity storage.Dante Issac Aleman | 2021
