Embodiment Construction

[0206] The first embodiment of the present invention is in Figure 4A is shown in , and relates to a stand-alone CES system, showing a liquefaction unit (1), a cryogenic tank (2) and a power recovery unit (3), which demonstrates the Figures 5A-5FA power island (33) of any configuration shown in , each of which is also an embodiment of the invention. This stand-alone CES system has compression heat recirculation devices (11, 12, 15, 16, 12A, 16A) and a first separate closed double loop that transfers the cold heat energy embedded in the refrigerant to the process stream of the liquefaction unit ( 130). The thermal energy of the heat supplied to the working fluid of the power recovery unit via at least one power recovery heater may be derived from the heat of compression through a second (11, 12, 12A) and third (15, 16, 16A) separated closed double loop recirculation device. Although it is a self-contained system, it is possible to have an embodiment that not only uses the t...

Abstract

Power recovery sub-systems, cryogenic energy storage systems, and methods of capturing, storing, and re-using thermal energy are disclosed.

Description

technical field [0001] The present invention relates to power recovery subsystems and cryogenic energy storage systems with liquefaction and power recovery subsystems, and in particular to systems and methods for harvesting, storing and reusing thermal thermal energy. Background technique [0002] The electricity transmission and distribution network (or grid) must balance the generation of electricity with the demand from consumers. This is usually achieved by modulating the generation side (supply side) by switching the power plants on and off and operating some power plants at reduced load. Since most existing thermal and nuclear power plants are most efficient when operating continuously at full load, there is an efficiency loss when balancing the supply side in this way. The introduction of significant intermittent renewable generation capacity, such as wind turbines and solar collectors, into the grid is expected to further complicate the balancing of the grid by crea...
