A thermal energy storage system includes a container positioned within a surrounding body of water and comprising a container wall. The wall has an interior surface exposed to and defining an internal volume of the container and has an exterior surface opposite the interior surface and exposed to the surrounding body of water. The internal volume is substantially full of water, and the container is configured to thermally separate water within the internal volume along the interior surface from water of the surrounding body of water along the exterior surface. A thermal source in thermal communication with the water within the internal volume is configured to transfer a thermal potential to the water within the internal volume.

1. A thermal energy storage system comprising: a container positioned within a surrounding body of water and comprising a container wall having:an interior surface exposed to and defining an internal volume of the container; andan exterior surface opposite the interior surface and exposed to the surrounding body of water;wherein the internal volume is substantially full of water;wherein the container is configured to thermally separate water within the internal volume along the interior surface from water of the surrounding body of water along the exterior surface;a pump connected to the container so as to be in fluid communication therewith, the pump configured to pump water from the internal volume and pump water to the internal volume;a heat exchanger connected to the pump and in fluid communication with the pump and the container; anda compressor and expander system in thermal communication with the water within the internal volume and configured to transfer a thermal potential to the water within the internal volume via the heat exchanger and the pump. 2. The system of claim 1 wherein the container wall is collapsible. 3. The system of claim 2 wherein the container wall comprises one of a fabric material and a polymer film. 4. The system of claim 2 further comprising an insulation material coupled to and positioned about a first portion of the container so as to increase a thermal insulation of the first portion, with a second portion of the container remaining uncovered by the insulation material so as to remain free to exchange heat with the surrounding body of water. 5. The system of claim 4 wherein the insulation material comprises a polymer material entraining a gas. 6. The system of claim 4 wherein the insulation material comprises a multi-polymer layer material, wherein a space between each polymer layer allows water from the body of water to be positioned between each polymer layer. 7. The system of claim 2 wherein the container comprises a substantially ellipsoidal dome. 8. The system of claim 2 further comprising baffling positioned within the interior volume and configured to impede circulation of the water within the interior volume. 9. The system of claim 2 wherein the thermal storage system further comprises a first pipe positioned within the container and extending a first distance from a top of the container in a first direction, the first pipe having a first end connected to the pump and a second end having an opening configured to fluidly couple an interior volume of the first pipe with an interior volume of the container. 10. The system of claim 9 wherein the thermal storage system further comprises a second pipe positioned within the container and extending a second distance from the top of the container in the first direction, the second distance being greater than the first distance; wherein the second pipe has a first end connected to the pump and a second end having an opening configured to fluidly couple an interior volume of the second pipe with an interior volume of the container. 11. The system of claim 10 wherein the pump is configured to: draw cold water through the second pipe to supply cold water from the container to the heat exchanger, so as to transfer heat into the cold water; andsupply heated water from the heat exchanger and down through the first pipe to the container. 12. The system of claim 2, where the thermal source is a pressure-modifying device. 13. The system of claim 1 wherein the thermal source, in being configured to transfer the thermal potential, is configured to transfer heat to the water within the internal volume to raise the temperature of the water within the internal volume to a temperature exceeding its boiling point at 1 atmosphere. 14. The system of claim 1 further comprising an end flow director coupled to each of the first pipe and the second pipe at the second end thereof adjacent to the opening, the end flow director configured to direct the water to flow from the opening in a direction substantially horizontal to an orientation of the pipe. 15. The system of claim 1 wherein the compressor and expander system is operable in a first mode to compress a fluid and is operable in a second mode to expand a fluid. 16. The system of claim 15 wherein heat generated during the fluid compression performed by the compressor and expander system is stored in the water within the internal volume of the container, via the heat exchanger. 17. The system of claim 15 wherein the compressor and expander system is operated in reverse when expanding fluid in the second mode as compared to when compressing fluid in the first mode.
