WebJan 5, 2024 · Pumped storage hydropower (PSH) represents the bulk of the United States' current energy storage capacity: 23 gigawatts (GW) of the 24 GW national total (Denholm et al. 2024). This capacity was largely built between 1960 and 1990. PSH is a mature and proven method of energy storage with competitive round-trip efficiency and long life spans. WebTypically, closed loop systems have fewer impacts, because after the initial filling of the reservoir, there is no transfer of water from a free flowing source other than the potential need for evaporation make-up water, thereby greatly reducing aquatic issues (fish passage, sediment migration, etc.). The reservoirs may be natural or artificial.
