High-head seawater pumped hydro energy storage. By 1999, the Okinawa Yanbaru SPHS Power Station started operation and became the first PHS facility in the world to use seawater to store energy [32].

Nevertheless, Snowy 2.0 will store 350,000 megawatt-hours—nine times Fengning''s capacity—which means each kilowatt-hour it delivers will be far cheaper than batteries could provide, Blakers says. Yet his atlas shows that Australia has many sites more technically ideal than Snowy 2.0.
The study found the facility could be in operation by 2023, at an optimal size of 225MW with storage of 1,770MWh. It would cost $477 million up front with running costs of $11-12 million per year. This works out to $2.1 million per MW of capacity, or $270 per KWh of storage.

Special issues regarding the use of seawater from the PSS (pumped storage system), such as the use of materials for the construction of the penstock, the construction of the upper reservoir, placing the pump station and the hydro power plant on the coast and the selection of pump and hydro-turbine models are presented thoroughly.
A new form of PSH, called Ground-Level Integrated Diverse Energy Storage (GLIDES) systems, pumps water into vessels full of air or other pressurized gases. As more water fills the vessel, it compresses the gases. When the grid needs electricity, a valve opens and the pressurized gas pushes the water through a turbine, which spins a
