Technical FAQs 4

What is underground energy storage?

The underground energy storage system involves not only energy fuels (oil, natural gas, hydrogen, etc.) but also thermal or cold energy storage and electric energy storage, such as compressed air energy storage. Compared with caverns (e.g., salt caverns and rock caverns), underground energy storage in porous media occupies much larger market.

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 large-scale underground energy storage technology?

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. It forms the technological basis of achieving carbon peaking and carbon neutrality goals.

How deep is the underground space for energy storage?

The underground space for energy storage mainly includes porous or fractured porous media (e.g., depleted oil and gas reservoirs, aquifers) and caverns (e.g., salt caverns, rock caves, abandoned mines or pits) (Jannel and Torquet, 2021) (Fig. 3). The depth can range from several hundred meters to several kilometers (Kabuth et al., 2017).
