Abstract
An underwater energy storage system includes a tank for storing a compressed gas that is adapted to be stored underwater. The tank includes at least one water opening through which water from surrounding environment can flow into and out of the tank, and at least one gas opening through which the compressed gas is received. The underwater energy storage system further includes at least one duct communicating between the at least one opening for gas flow and a source of compressed gas and a compartment constructed over a roof of the tank, wherein said compartment is adapted for receiving weights at a sinking site of the tank.
Claims38
An underwater energy storage system comprising:
- a tank for storing a compressed gas that is adapted to be stored underwater, wherein the tank encloses a constant volume,
- the tank comprising:
- at least one water opening through which water from surrounding environment can flow into and out of the tank;
- at least one gas opening through which the compressed gas is received;
- and
- floating structures housed in the tank and adapted to cover a surface of water contained in the tank;
- at least one duct communicating between the at least one opening for gas flow and a source of compressed gas;
- and
- a compartment constructed over a roof of the tank, wherein said compartment is adapted for receiving weights at a sinking site of the tank.
An underwater energy storage system comprising:
- a plurality of tanks for storing compressed air underwater, wherein each of the tanks include at least one water opening through which water from a surrounding water body freely flows into and out of the tank and at least one air opening for receiving and discharging the compressed air, wherein free flow through the at least one water opening is responsive to air flow into and out of the tank;
- floating structures housed in at least one of the plurality of tanks and adapted to cover a surface of water contained in the at least one of the plurality of tanks;
- a first duct for communicating air flow between the at least one air opening of at least one of the plurality of tanks and a source of compressed air;
- and
- at least one second duct for communicating air flow between the at least one air opening of each tank.
