Could reusing oil and gas wells offer green energy storage solution?

Journal of Energy Storage, 2025; 110: 115317 DOI: 10.1016/j.est.2025.115317 Penn State. "Reusing old oil and gas wells may offer green energy storage solution." ScienceDaily. ScienceDaily, 18 March 2025. < / releases / 2025 / 03 / 250318141007.htm>.

What is energy storage?

Energy storage encompasses an array of technologies that enable energy produced at one time, such as during daylight or windy hours, to be stored for later use. LPO can finance commercially ready projects across storage technologies, including flywheels, mechanical technologies, electrochemical technologies, thermal storage, and chemical storage.

What are the five underground large-scale energy storage technologies?

In this work, the characteristics, key scientific problems and engineering challenges of five underground large-scale energy storage technologies are discussed and summarized, including underground oil and gas storage, compressed air storage, hydrogen storage, carbon storage, and pumped storage.

What is the difference between manufacturing and deployment of energy storage systems?

Manufacturing: Projects that manufacture energy storage systems for a variety of residential, commercial, and utility scale clean energy storage end uses. Deployment: Projects that deploy residential, commercial, and utility scale energy storage systems for a variety of clean energy and clean transportation end uses.

Where can I find large-scale underground energy storage technology?

1 China Energy Digital Technology Group Co., Ltd., Beijing 100044, P. R. China 2 Wuhan Institute of Geotechnical Mechanics of Chinese Academy of Sciences, Wuhan 430071, P. R. China Large-scale underground energy storage technology uses underground spaces for renewable energy storage, conversion and usage.

Could reusing oil & gas wells save energy?

Reusing depleted oil and gas wells would allow operators to access geothermal heat in hot rock formations underground, eliminating upfront costs of drilling new wells and potentially making the technology more appealing to industry, the scientists said.
