Analysis reveals benefits of hydropower for grid-scale energy storage

Closed-loop pumped storage hydropower systems rank as having the lowest potential to add to the problem of global warming for energy storage when accounting for the full impacts of materials and construction, according to analysis conducted at the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL). These systems rely on water flowing between two reservoirs to generate and store power.
