    Abstract: A hybrid compressed air energy storage system is provided. A heat exchanger 114 extracts thermal energy from a compressed air to generate a cooled compressed air stored in an air storage reservoir 120, e.g., a cavern.

An expander 140 is solely responsive to the heated compressed air by heat exchanger 124 to produce power and generate an expanded air. Expander 140 is effective to reduce a temperature of the expanded air by expander 140, and thus a transfer of thermal energy from an expanded exhaust gas received by a recuperator 146 (used to heat the expanded air by the first expander) is effective for reducing waste of thermal energy in exhaust gas cooled by recuperator 146.

A standardized machinery string consisting of a multi-shaft gas turbine with no more than three compressor bodies, where the compressor bodies are applied to one or more refrigerant compressors employed in one or more refrigerant cycles (e.g., single mixed refrigerant, propane precooled mixed refrigerant, dual mixed refrigerant). The standardized machinery strings and associated standardized refrigerators are designed for a generic range of feed gas composition and ambient temperature conditions and are installed in opportunistic liquefaction plants without substantial reengineering and modifications. The approach captures D1BM (“Design 1 Build Many) cost and schedule efficiencies by allowing for broader variability in liquefaction efficiency with location and feed gas composition.

  • Patent number: 11073125
    Abstract: In one aspect, a system for generating electricity based on water flow is disclosed. The system comprises a first pipe fitting, a turbine, and a second pipe fitting. The first pipe fitting couples to a pipe that supplies a fluid to a building. The turbine is in fluid communication with the first pipe fitting and rotates in response to a kinetic energy of the fluid supplied by the pipe flowing through the turbine, generates electricity in response to rotation of the turbine, and reduces a pressure of the fluid from a first pressure to a second pressure. The second pipe fitting couples the turbine to an input pipe of the building. The turbine further comprises a conversion circuit that conditions the generated electricity for consumption by the building and conveys the generated electricity to the building via one or more conductors.

  • Patent number: 11050322
    Abstract: An integrated flywheel energy storage device includes an inner stator having an interior support component and multiple stator cores connected to the interior support component, each with an associated stator coil arranged in multiple electrical phases. An outer rotor housing supports multiple active rotor poles which each face inward toward the stator cores, the active rotor poles being permanent magnets, copper relining, an induction squirrel cage, or variable reluctance poles. A vacuum containment housing surrounds the outer rotor housing. The outer rotor housing has a rotational moment of inertia that stores kinetic energy as a kinetic battery, allowing the device to deliver multi-phase electrical power when required. High power density is achieved by integrating the flywheel into the outer rotor housing. The device additionally functions as a gyroscope for stabilizing an exterior structure, or as a gyroscopic reference for navigational purposes when supported on a gimballed platform.
