Abstract

Systems and methods for producing energy from a geothermal formation are disclosed. A heat exchanger can be disposed within a well to absorb heat from a geothermal formation. The heat exchanger can besupported within the well using a high thermal conductivity material. The heat exchanger is connected to an organic Rankine cycle engine including a secondary heat exchanger and a turbine. The primary and secondary heat transfer fluids are chosen to maximize efficiency of the organic Rankine cycle.

Description

Background technique [0001] Conventional systems for generating electrical power for public consumption and utilization include nuclear power, fossil fuel powered steam generation plants, and hydroelectric power. Operation and maintenance of these systems are expensive and use a large amount of natural resources, and in some cases lead to excessive pollution through hydrocarbon burning or disposal of spent nuclear fuel rods. Furthermore, even renewable energy resources such as solar and wind powered systems are only operational in some locations on average for only a few hours per day, while geothermal systems can be operated on an approximately 24 / 7 basis as needed. [0002] Therefore, there is a need in the art for systems and methods for inexpensively generating clean electricity that is available on an approximately 24 / 7 basis and that does not rely on the import of petroleum materials or the construction of multi-billion dollar power plants. There is a further need for s...
