Utilizing abandoned coal mines fo compressed air energy storage (CAES) presents a promising solution. Considering the widespread occurrence of high water levels in southern China''s coal mines, a novel flooded coal mine roadway compressed air energy storage (FM-CAES) system is proposed.
For example, Wang et al. explored the recovery of thermal energy from water resources in abandoned coal mines using Shandong Province, China, as a case study. Colas et al. examined the operational workflow of using abandoned coal mines for sustainable underground storage.
Significant research progress has been made in using abandoned mines for large-scale energy storage. For example, Wang et al. explored the recovery of thermal energy from water resources in abandoned coal mines using Shandong Province, China, as a case study.
The compressed air is stored in the tunnels of abandoned coal mines. Simultaneously, the heat generated during compression is transferred via intercoolers to a thermal storage tank. At night, when the electricity demand increases and supply tightens, the high-pressure air is reheated and expanded through a turbine to generate electricity.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
