6 FAQs about [Coal mine tunnel energy storage system pictures]

Can underground space energy storage technology be used in abandoned coal mines?

The underground space resources of abandoned coal mines in China are quite abundant, and the research and development of underground space energy storage technology in coal mines have many benefits.

What is coal underground thermal energy storage?

Coal underground thermal energy storage (CUTES) is a form of energy storage that makes extensive use of the underground highways in closed mines as a place to store energy and to offer heating and cooling in the winter and summer months, respectively.

Can compressed air energy storage be used in coal mines?

However, the key issues, such as the uneven heat transfer of the system and the corrosion and scaling of the heat transfer medium, need to continue to be addressed. (3) The potential for compressed air energy storage in coal mines' underground spaces is enormous, and it can be used with less costly excavation.

Why is the underground space of a coal mine important?

This is because the underground space of a coal mine has the following advantages: (1) Rich space: the underground coal mine has a vast space, especially underground cavities such as goafs and abandoned roadways, which can be used to store a large amount of energy.
