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).
In the energy transition, the promotion of renewable sources entails the development of storage technologies to manage the mismatch between energy production and demand. In this scenario, the use of CAES (Compressed Air Energy Storage) technology enables the efficient and cost-effective storage of l
2.1.2 Historical Development Technology of underground thermal energy storage has a 40-year history, which began with cold storage in aquifers in China. Outside China, the idea of UTES started with more theoretical work in the early 1970s. Interest in UTES systems increased rapidly in the 1980s and several pilot and
Therefore, we have reason to believe that for future large-scale energy storage technology, as well as for short-term energy storage peak-shaving, the construction scale of salt cavern CAES plants will not be smaller than the current PHES at least. 4.2. 4.2.1.

In addition, the comprehensive development and utilization of the legacy resources of abandoned coal mines and the use of abandoned coal mines as a breakthrough point in the industry are bound to provide a unique industry development path for the realization of carbon neutrality goals. 2. The challenge of carbon neutrality to coal
With sustained and rapid development of its economy, China''s external energy dependency increases. The net imports of petroleum products, including crude oil, oil, liquefied petroleum gas, etc., have reached 2.931 × 10 8 tons. The import of liquefied natural gas (LNG) and pipeline gas is 425 × 10 8 m 3, accounting for about 28.9% of
Other mechanical energy sources are also established as mature technology, like underground compressed air storage (CAES), which is a technically viable alternative. In order to increase its competitiveness, it is necessary for the compression system to have an energy storage system or thermal energy management
Energy storage systems are required to increase the share of renewable energy. Closed mines can be used for underground energy storage and geothermal generation. Underground closed mines can be used as lower water reservoir for UPHES. CAES systems store energy in the form of compressed air in an underground reservoir.
It is anticipated that utilizing the underground space in abandoned mines to build and operate pumped-storage hydroelectricity (PSH) plants can reduce capital investment and geological constraints
