6 FAQs about [The difference between coal mines and new energy storage]

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.

Can abandoned coal mine facilities be used to generate energy?

Thus, the abandoned mine facilities are efficiently used to generate both electrical and thermal renewable energy. Fig. 5. Combined design of underground energy storage systems (UPHES and CAES) and geothermal utilization in an abandoned underground coal mine.

Is a coal mine a suitable place for energy storage?

As a kind of abandoned mine, the coal mine has gradually developed into a more suitable place for energy storage.

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.

Should energy storage be a key issue in mining?

The second place that energy storage emerged as a key issue was less expected: in their vision of “smart” and “sustainable” mines, mining companies see advanced energy storage as a key component of the so-called “future of mining” and their vision of the “mine of the future”.

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.
