Embodiments disclosed herein enable routine autonomous execution of at least some major phases of aerostat operation in response to commands from human or automated external operators, a built-in decision-making capacity, or both. Various embodiments combine one or more actively controlled tethers, aerodynamic aerostat control surfaces, mechanical assistive devices (e.g., jointed arms attached to a ground station), and/or active propulsors attached to the aerostat to govern aerostat behavior during launch, flight, and landing phases of operation. Some embodiments enable automatic autonomous performance of all phases of routine post-commissioning aerostat operation, including launch, flight, and landing, without any routine need for availability of a human crew.

In various embodiments, foam is compressed to store energy and/or expanded to recover energy.

Systems and methods for efficient two-phase heat transfer in compressed-air energy storage systems

In various embodiments, compressed-gas energy storage and recovery systems include a cylinder assembly for compression and/or expansion of gas, a reservoir for storage and/or supply of compressed gas, and a system for thermally conditioning gas within the reservoir.

Heat exchange with compressed gas in energy-storage systems

In various embodiments, a mechanical assembly and/or storage vessel is fluidly coupled to a circulation apparatus for receiving pressurized heat-transfer fluid from an outlet at a first elevated pressure, boosting a pressure of the heat-transfer fluid to a second pressure larger than the first pressure, and returning heat-transfer fluid to an inlet at a third pressure.

Systems and methods for efficient pumping of high-pressure fluids for energy

The invention relates to systems and methods for rapidly and isothermally expanding and compressing gas in energy storage and recovery systems that use open-air hydraulic-pneumatic cylinder assemblies, such as an accumulator and an intensifier in communication with a high-pressure gas storage reservoir on a gas-side of the circuits and a combination fluid motor/pump, coupled to a combination electric generator/motor on the fluid side of the circuits. The systems use heat transfer subsystems in communication with at least one of the cylinder assemblies or reservoir to thermally condition the gas being expanded or compressed.

Systems and methods for energy storage and recovery using rapid isothermal gas expansion and compression

The invention relates to methods and systems for the storage and recovery of energy using open-air hydraulic-pneumatic accumulator and intensifier arrangements that combine at least one accumulator and at least one intensifier in communication with a high-pressure gas storage reservoir on a gas-side of the circuits and a combination fluid motor/pump, coupled to a combination electric generator/motor on the fluid side of the circuits.

Systems and methods for energy storage and recovery using compressed gas

In various embodiments, heat is exchanged with a gas being compressed or expanded within an energy storage and recovery system without the use of flexible hoses.

Fluid circulation in energy storage and recovery systems

In various embodiments, coupling losses between a cylinder assembly and other components of a gas compression and/or expansion system are reduced or eliminated via valve-timing control.

Dead-volume management in compressed-gas energy storage and recovery systems

In various embodiments, efficiency of energy storage and recovery systems employing compressed air and liquid heat exchange is improved via control of the system operation and/or the properties of the heat-exchange liquid.

High-efficiency heat exchange in compressed-gas energy storage systems

In various embodiments, dead space and associated coupling losses are reduced in energy storage and recovery systems employing compressed air.

Systems and methods for reducing dead volume in compressed-gas energy storage systems

In various embodiments, compressed-gas energy storage and recovery systems feature one or more valves, which may be disposed within end caps of cylinder assemblies in which gas is expanded and/or compressed, for admitting fluid to and/or exhausting fluid from the cylinder assembly.
