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.
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.
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 ].
Various energy storage technologies and risks in coal mine are analyzed. A significant percentage of renewable energy is connected to the grid but of the time-space imbalance of renewable energy, that raises the need for energy storage technologies.
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.
