Sizable Energy addresses electricity storage through an offshore pumped-hydro design using saturated brine and ocean depth. Its public site identifies a single named system and describes the engineering components that work together within it.
Potential locations in more than fifty countries describe prospective siting opportunities for the company’s storage architecture.

Sizable Energy’s offshore pumped-hydro system connects a floating brine reservoir with a reservoir on the seabed. Reversible pump-turbines move saturated sea-salt brine between them, using ocean depth to provide the elevation difference needed for storage.
The company presents a modular architecture intended for long-duration electricity storage.

Sizable Energy addresses the long-duration energy storage market, where power grids need storage that can bridge renewable-energy intermittency over longer periods than conventional short-duration batteries. The company cites a need for up to 120 terawatt-hours of long-duration storage by 2040.
Its market thesis is that onshore pumped hydro remains reliable but is constrained by geography, development timelines, and environmental concerns. Sizable Energy argues that offshore pumped hydro can expand deployment potential by using ocean depth and maritime infrastructure.

Sizable Energy’s design places the storage reservoirs offshore, so the company emphasizes avoiding land consumption associated with onshore reservoirs. Its use of reversible pump-turbines draws on established pumped-hydro machinery.
The company also describes modular construction and potential integration with floating wind and solar generation as design benefits.
