Some renewable energy sources, like wind power, are intermittent and any excess energy can be difficult to store. resulting in storage space that is gas-tight and suitable for the storage of natural gas

Supporting the Low-Carbon Energy Transition

These could be stored belowground until energy demand rises, days or months later. We are studying the mechanics, capacity and implications of underground energy storage. We are also currently assessing how much space might be available below the Nation''s surface to store energy resources like natural gas or hydrogen.

power supply drops below power demand. Battery storage is one method to store power. However, geologic (underground) energy storage may be able to retain vastly greater quantities of energy over much longer durations compared to typical bat- R.K., 2021, The design space for long-duration energy storage in decarbonized power systems: Nature

Characterizing Hydrogen Storage Potential in U.S. Underground

Creating hydrogen during periods of energy surplus and storing it underground is one long-duration, low-emission, energy storage option that can balance supply and demand for an entire electric grid. In the United States (U.S.), existing underground gas storage (UGS) facilities are a logical first place to consider subsurface hydrogen storage

Assessing the technical potential for underground thermal energy

Underground thermal energy storage (UTES) can play a role in energy decarbonisation by storing waste heat from space cooling, refrigeration, data processing, industrial processes, harvested summer solar thermal energy or even heat generated by surplus renewable (solar or wind) electricity with fluctuating supply.

Underground Gravity Energy Storage: A Solution for Long-Term

The proposed technology, called Underground Gravity Energy Storage (UGES), can discharge electricity by lowering large volumes of sand into an underground mine through the mine shaft. Newbery, D.
