A thermal energy storage system for comprising a working fluid to store and transfer thermal energy between a heat source and a thermal load and a plurality of vessels to store the working fluid. Each vessel has an interior region and a floating separator piston in the interior region to separate a hot portion from a cold portion of the working fluid. There is a first manifold thermally coupled to an output of the heat source and to an input of the thermal load and fluidly coupled to the interior region of the vessels and a second manifold thermally coupled to an input of the heat source and an output of the thermal load and fluidly coupled to the interior region of the vessels. The vessels are arranged in parallel.

A hybrid geothermal electrical power generation system that utilizes the heat from a deep geothermal reservoir to vaporize a working fluid, such as steam, CO.sub.2 or an organic fluid. The vaporized working fluid is used to turn a turbine connected to an electrical power generator. A solar collector may be used to increase the temperature of the working fluid during sunlight hours and a thermal storage unit may be utilized to increase the temperature of the working fluid during the night. A supercritical CO.sub.2 power generation cycle may be used alone or in combination with a steam turbine power generation cycle to utilize all of the heat energy. A vapor compression cycle, a vapor absorption cycle may be utilized to provide heating and cooling. A low temperature shallow geothermal reservoir may be used as a heat exchanger to regulate or store excess heat.

A system for the generation of mechanical or electrical energy from heat energy, where increasing a height or pressure in a liquid chamber of the system containing a liquid increases an efficiency of the system up to a hundred percent or increases such efficiency until a critical temperature or pressure of the vapor (gas) is reached at the bottom of liquid chamber or in the boiler of the system depending upon the increment in height, pressure and the type of liquid used in the system. An increase in height of the system for such increased efficiency can be adjusted to a smaller height by maintaining a series of liquid and gas chambers where the vapor flows through the series of chambers or by adding pressure valves. The heat energy from high to low temperature sources can be convened to mechanical and electrical energy.

A system for providing electrical power includes a high temperature heat source, an ambient temperature heat sink, an ORC generator, a solar thermal collector, and an SDES device. The ORC generator includes a generator working fluid with a boiling temperature greater than an ambient temperature of the ambient temperature heat sink, and the generator working fluid receives heat from the high temperature heat source and exhausts heat to the ambient temperature heat sink. The solar thermal collector is in thermal communication with the high temperature heat source to heat the high temperature heat source. The solar thermal collector includes a photovoltaic (PV) module, and the solar thermal collector is configured to convert a first portion of sunlight to thermal energy and a second portion of the sunlight to electrical energy. The SDES device receives electrical energy from one of the ORC generator and the PV module.
