Deep underground energy storage

What is Geologic Energy Storage?

However, geologic (underground) energy storage may be able to retain vastly greater quantities of energy over much longer durations compared to typical battery storage. Geologic energy storage also has high flexibility; many different types of materials can be used to store chemical, thermal, or mechanical energy in a variety of underground

Overview of Large-Scale Underground Energy Storage

Long-term storage of fluids in underground formations has routinely been conducted by the hydrocarbon industry for several decades, with low quality formation water produced with oil being reinjected in saline formations to minimise environmental impacts, or in acid-gas injection techniques to reduce the H 2 S and CO 2 stripping from natural gas. .

A comprehensive review of geothermal energy storage: Methods

Deeper or deep geothermal sources are often used for seasonal or large-scale energy storage. In a deep geothermal storage system, heat is extracted from rocks several kilometers underground. Aquifer thermal energy storage has the lowest cost compared to other natural forms of underground energy storage [42].
