Abstract: An open brayton cycle power generation system is enabled and improved by integration of an energy storage system utilizing cryogenic storage of atmospheric gas. A particular improved system is an open brayton cycle power generation system in which the heating source is Concentrating Solar Power. Multiple embodiments are described which permit various modes of operation and improved overall efficiency.

Abstract: Disclosed are a method and system involving pressurizing an atmospheric gas stream to form at least a compressed atmospheric gas stream, directing the compressed atmospheric gas stream to a first regenerator for cooling, pressurizing to above a second predetermined pressure to form at least a supercritical atmospheric gas stream, directing the supercritical atmospheric gas stream to a second regenerator for cooling, reducing pressure to form at least a liquefied atmospheric gas stream, selectively storing the liquefied atmospheric gas stream, pressurizing the liquefied atmospheric gas stream to form at least a pressurized liquefied atmospheric gas stream, heating the pressurized liquefied atmospheric gas stream in the second regenerator to form at least a heated stream, expanding the heated stream to form at least a medium pressure atmospheric gas stream, directing the medium pressure atmospheric gas stream to the first regenerator, and heating the medium pressure atmospheric gas stream in the first regenerat

Abstract: Disclosed is a regenerator, a regeneration process, and a liquid polymer mixture for periodic cooling, storing, and heating of atmospheric gas. The regenerator, the regeneration process, and the liquid polymer mixture involve a liquid polymer that remains in contact with a thermally conductive solid material during a first operational period and a second operational period of a regeneration process.

Abstract: Disclosed is a method and a system. The method and system involve compressing an atmospheric gas stream to form a supercritical atmospheric gas stream, forming at least a first stream from the supercritical atmospheric gas stream, directing the first stream to a regenerator for cooling to form a first cooled stream, directing the first cooled stream from the regenerator, expanding the first cooled stream to form a liquefied atmospheric gas stream, storing at least a portion of the liquefied atmospheric gas stream, pressurizing at least a portion of the stored portion of the liquefied atmospheric gas stream, and heating at least a portion of a pressurized liquefied atmospheric gas stream in the regenerator. In the method and system, refrigeration below the critical temperature of the atmospheric gas is directly or indirectly provided to at least one portion of the system from a non-combustible source.
