Repurposing a deep geothermal exploration well for borehole

UTES technology operates by storing heat in subsurface fluid and solid (aquifer thermal energy storage) (e.g., [27]) or in solid rocks only (via borehole thermal energy storage (BTES)) (e.g., [34]). This study focuses on deep BTES, where limited research evaluating the potential of deeper systems has been conducted.

The temperature gradient of injection well V 2 and production well V 3 was about 1.25 °C/m, indicating that after the two injection wells adjacent to the middle of Fig. 6 became the injection

Geothermal Power Production, Hybridization and Storage

Geothermal energy storage systems can be classified into various categories according to their design and functioning. An example of such a system is the Advanced Geothermal Energy Storage (AGES) system (Bokelman et al., 2020). It works by transferring heat from different sources into a subsurface well with low temperatures.

Repurposing abandoned wells for geothermal energy: Current

A debate rages as to whether abandoned oil and gas wells have to be sealed to prevent methane leakage – a potent greenhouse gas – or whether the valuable infrastructure can be repurposed for environmental benefit. One viable solution is to repurpose such wells for the recovery of low-grade geothermal energy and simultaneously produce a revenue stream,

Geothermal battery energy storage

The Geothermal Battery Energy Storage concept (GB) has been proposed as a large-scale renewable energy storage method. This is particularly important as solar and wind power are being introduced into electric grids, and economical utility-scale storage has not yet become available to handle the variable nature of solar and wind.
