Abstract
A subterranean energy storage and retrieval system, having a wellbore; an energy storage cell placed in the wellbore; and an electrical connection attached to the energy storage cell to a surface of the wellbore. The energy storage system is managed and regulated by a power management system coupled to rechargeable power cells. A bypass circuit is utilized to remove specific energy storage cells from the circuit. Temperature regulation is managed geothermally through the energy storage housing.
Claims19
A subterranean energy storage and retrieval system, the system comprising:
- a wellbore including a wellbore casing and a hydraulic seal disposed within the wellbore casing to form a sealed interval of the wellbore;
- an energy storage cell disposed in the wellbore casing within the sealed interval of the wellbore;
- and
- an electrical connection extending from the energy storage cell to a surface of the wellbore.
A method for subterranean energy storage and retrieval, the method comprising:
- deploying an energy storage cell placed in a sealed interval of a casing of a wellbore, the casing including a hydraulic seal to define the sealed interval within the wellbore;
- and
- extending an electrical connection attached to the energy storage cell to a surface of the wellbore.
A method, the method comprising:
- sealing an interval of a casing within a wellbore;
- placing a plurality of energy storage cells within the sealed interval of the casing in the wellbore;
- extending an electrical connection from the plurality of energy storage cells to a surface of the wellbore;
- and
- extracting electrical energy from the energy storage cells at the surface of the wellbore via the electrical connection.
