Abstract
An energy island system arranged related to a body of water with a seafloor, a surface and a depth over an underground is disclosed. The system comprises a structurally rigid shell (1) extending from the seafloor to above the water surface, inclosing a lagoon of the body of water, material with a negative buoyancy stacked around the shell (1) forming a gravity stabilized wall (2), and a tunnel (5) established in the wall (2), providing for hydraulic communication between the surrounding body of water and the interior of the shell (1). Further, a method for construction of an energy island is disclosed.
Claims18
An energy island construction method, wherein the method comprises:
- selecting a body of water with a seafloor, a water surface and a depth over an underground;
- arranging a structurally rigid shell extending from the seafloor to above the water surface, enclosing a lagoon of the body of water;
- stacking material with a negative buoyancy around the shell forming a gravity stabilized wall;
- establishing a tunnel in the wall, providing for hydraulic communication between a surrounding body of water and an interior of the shell;
- capping the tunnel with a capping structure, and evacuating water from the lagoon;
- the construction method further comprising at least one of:
- excavating a shaft in the underground below the interior of the shell into a permeable substratum;
- excavating at least one branching tunnel, the branching tunnel at least partially located in the permeable substratum, and in hydraulic communication with the shaft;
- and
- arranging a turbine/generator combination in the shaft;
- or
- excavating a shaft in the underground below the lagoon into a salt deposit below an impermeable stratum;
- and
- arranging an input tube structure allowing water to pass from the body of water into the salt deposit establishing a cavity in the salt deposit.
