Geologic energy storage | U.S. Geological Survey

Introduction As the United States transitions away from fossil fuels, its economy will rely on more renewable energy. Because current renewable energy sources sometimes produce variable power supplies, it is important to store energy for use when power supply drops below power demand. Battery storage is one method to store power.

6 FAQs about [Geological power storage]

What is geologic energy storage?

Can geologic energy storage reduce electricity costs?

An electrical grid that uses long duration energy storage projects with over 100 hours of stored power could result in the greatest reduction in electricity costs (Sepulveda and others, 2021). Geologic energy storage is a practical solution that can store 100 or more hours of energy.

Why is energy storage important in the geological subsurface?

Does geologic energy storage still exist?

Much of the technol-ogy for geologic energy storage is still undergoing research and development (Crotogino and others, 2017; Matos and others, 2019), although several industrial-sized underground storage projects are already operating in the United States and world-wide (fig. 1).

How can geological formations ensure large-scale energy storage?

One way to ensure large-scale energy storage is to use the storage capacity in underground reservoirs, since geological formations have the potential to store large volumes of fluids with minimal impact to environment and society.

How does a geological subsurface store energy?

The geological subsurface, particularly porous formations, can offer grid-scale energy storage options , , either by storing a chemical energy carrier, such as hydrogen or methane , , or by storing mechanical energy as compressed air , , , or as sensible heat (e.g., , ).
