From Europe to North America, former coal mines are transforming into renewable energy storage sites. These abandoned shafts now serve as gravity batteries, storing excess energy by lifting and lowering heavy weights. . As Zhongbo Su et al discussed in their research published in the Journal of Energy Storage, many of these mines have complex geological conditions and phased shutdown plans, while research on the development and utilisation of them is somewhat lacking. Underground Gravity Energy Storage system: A schematic of different system sections., Energies, 2023) To have a functional power grid. . Coal mines, whether operating or abandoned, represent a legacy of the Industrial Revolution but also hold transformative potential. With awareness of the need to reduce greenhouse gas (GHG) emissions and the pressing need to meet growing global energy demand, it is vital to explore new directions. . Pumped Storage Hydropower (PSH) provides over 90% of the nation's grid-scale energy storage, playing a critical role in balancing electricity supply and demand. Sounds like sci-fi? Not in China.
