Explaining the Process and Technology

The process of harnessing geothermal energy involves advanced methods to capture heat from the Earth and optimize efficiency. These methods include:

• Enhanced Geothermal Systems (EGS): These systems utilize super-hot rock geothermal resources.
• Binary Plants: These plants generate electricity with minimal environmental impact.

By employing these innovative techniques, geothermal heat can be effectively converted into a reliable and sustainable energy source.

Enhanced geothermal systems work by injecting water into deep rock formations. The water is heated by the Earth’s natural geothermal energy and is then pumped back to the surface to generate electricity. Unlike traditional systems that rely on reservoirs of steam or hot water, EGS can be deployed in a wider range of locations, significantly increasing geothermal energy’s potential.

Binary plant technology complements this approach by using a secondary fluid with a lower boiling point. This fluid vaporizes to drive a turbine while preserving the primary geothermal resource. Companies like AltaRock Energy have successfully executed EGS projects, while Fervo Energy is pioneering new methodologies in binary systems. Insights from Halliburton’s geothermal projects illustrate these technologies’ practical applications in transforming energy landscapes.
