Types of Geothermal Power Plants

Making Electricity Using Geothermal Energy

There are three main types of geothermal power plant technologies: dry steam, flash steam, and binary cycle. The mechanism for converting the geothermal heat into electricity is part of the power plant design and generally depends on the state of the subsurface fluid (steam or water) and its temperature.1U.S. Dept. of Energy.

Let’s take a look at an introductory video from the U.S. Department of Energy that focuses on high temperature geothermal systems and power production.
