Abstract:
Systems and methods for improving the efficacy of a wind turbine farm by providing a mechanical compressed air energy storage solution to provide power to the grid when electricity demand requires it. Specifically, a system for storing compressed air energy recovered from a wind turbine driven compressor. The system can include a primary spherical pressure vessel configured for fluid communication with a compressed air source and a secondary spherical pressure vessel in fluid communication with the primary spherical pressure vessel. Air stored in the pressure vessels can then be discharged to a combustion power generator to generate supplemental electrical energy or through a turbo expander to directly generate electricity.

Abstract:
The present disclosure provides pumped heat energy storage systems that can be used to store and/or extract electrical energy. A pumped heat energy storage system of the present disclosure can store energy by operating as a heat pump, whereby net work input can be used to transfer heat from the cold side to the hot side. A working fluid of the system is capable of efficient heat exchange with heat storage fluids on a hot side of the system and on a cold side of the system. Such pumped energy storage systems can be beneficially integrated with steam plants to provided heating to the steam cycle.

Abstract:
Processes, systems, and apparatus are provided for producing a compressed process gas comprising light olefin such as ethylene. The process utilizes a pyrolysis reactor to produce the process gas. A power generator utilizes a turbine operated based on an Allam cycle to produce shaft power for operating one or more compressors involved in processing of the process gas while producing a reduced or minimized amount of CO2 that is released as a low-pressure gas phase product. Examples of using the shaft power for processing of the process gas can include compressing the process gas a process gas compressor powered by the produced shaft power and cooling the process gas using a refrigeration compressor powered by the produced shaft power.
Abstract:
A mounting system for supporting rotating machinery is described. The system corn-prises a base frame (9) having an upper side for mounting the rotating machinery (3, 5, 7), and a lower side. A set of main supporting members (13) are arranged according to a triangular arrangement and forming a three-point mounting arrangement defining a mounting plane. Moreover, a set of auxiliary supporting members (15), having a variable stiffness (S1,S2) in at least one direction, are provided and are configured and arranged such as to increase the stiffness thereof when the base frame (9) is subject to an overload, thus reducing load on the main supporting members (13).
