Seawater pumped storage hydropower (PSH) is a type of PSH in which the ocean acts as the lower reservoir and seawater is pumped to an upper reservoir to store energy 260 (see the figure).
Pumped storage hydropower is the world''s largest battery technology, with a global installed capacity of nearly 200 GW – this accounts for over 94% of the world’s long duration energy storage capacity, well ahead of lithium-ion and other battery types. Water in a PSH system can be reused multiple times, making it a rechargeable water battery.
The Fengning Pumped Storage Power Station is the one of largest of its kind in the world, with twelve 300 MW reversible turbines, 40-60 GWh of energy storage and 11 hours of energy storage, their reservoirs are roughly comparable in size to about 20,000 to 40,000 Olympic swimming pools.
These potential services and impacts are discussed in this section. Fig. 4: Economic and environmental factors and impacts. Pumped storage hydropower provides energy storage for power systems, ancillary grid services and water management, but also has economic and environmental impacts. GHG, greenhouse gas; VRE, variable renewable energy.
