6 FAQs about [Coal mine wind shaft energy storage system]

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 coal mining space be used for electrochemical energy storage?

The use of coal mining space for electrochemical energy storage has not yet been commercialized [ 95 ], and four key problems still need to be broken through, namely, site safety evaluation of underground space for coal development, construction of electrochemical energy storage geological bodies.

What is coal underground space electrochemical energy storage?

CUEES concept and technical requirements Coal Underground space Electrochemical Energy Storage (CUEES) makes full use of the underground space of coal mining to store or release electrical energy (various types of batteries) through reversible chemical reactions, so as to achieve efficient use of electrical energy, as shown in Fig. 20 [ 94 ].

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.

Are abandoned mine shafts a key problem in China's Energy Storage Technology?

However, studies on basic theories and key technologies are a pressing issue. Six key scientific problems have been identified in PSH development in abandoned mine shafts that are relevant to China’s national conditions, current resource structure, and relative status of energy storage technologies in China and other countries.
