The Impact of Hydrogeological Features on the Performance of Underground Pumped-Storage Hydropower (UPSH)

Underground pumped storage hydropower (UPSH) is an attractive opportunity to manage the production of electricity from renewable energy sources in flat regions, which will contribute to the expansion of their use and, thus, to mitigating the emissions of greenhouse gasses (GHGs) in the atmosphere. A...
