Energy storage in underground coal mines in NW Spain: assessment of an underground lower water reservoir and preliminary energy balance Renew. Energy., 134 ( 2019 ), pp. 1381 - 1391, 10.1016/j.renene.2018.09.042
Hard coal mines in Poland are very large, making them suitable for CAES technology. However, in order to apply the CAES technology in abandoned coal mines in Poland, further studies on the impact of this technology on the underground and above-ground environment are necessary. 4. Underground Gas Energy Storage.
Technical feasibility of abandoned coal mine goafs used as reservoirs is analyzed.. The pumped-hydro energy storage system using one goaf has an efficiency of 82.8%. • For a typical mining area, the effective storage capacity can reach 1.58 × 10 6 m 3.. Operating the proposed system in daily regulation mode is viable in China.
