Abstract
Certain examples present an improved compressed-air energy storage system. The system can include multiple sequential stages, in which accumulators are charged with air, which influences a hydraulic fluid to influence a pump/motor, and vice versa.
Claims11
An apparatus, comprising:
- a vessel defining at least one vessel port extending from an interior of the vessel to an exterior of the vessel;
- a moveable partition disposed in the vessel and sealed around the vessel port, partitioning a vessel interior into a vessel port side and a mandrel side;
- a mandrel disposed in the vessel in the mandrel side of the interior of the vessel and defining at least one mandrel port extending from the interior of the vessel to an exterior of the, wherein the moveable partition is configured to flex against the mandrel;
- and
- cooling channels disposed through the mandrel, sealed from the interior of the vessel.
2 more elements
An apparatus, comprising:
- a shell defining a plurality of interior volumes, with a respective hydraulic port extending from a respective interior of the volume to a respective exterior of the shell, and a respective pneumatic port extending from the respective interior of the volume to the respective exterior of the shell, wherein the plurality of volumes are divided by at least one common dividing wall including a fluid cooling port disposed through the at least one common dividing wall;
- and
- a respective moveable partition disposed in each of the volumes, with each moveable partition sealed around a respective hydraulic port , partitioning the respective volume interior into a respective hydraulic port side and a respective pneumatic port side, wherein a plurality of hydraulic ports are in fluid communication, configured to commute a pressure on one side of the common dividing wall to an opposite side of the common dividing wall.
