The third type of plant is a binary plant. The vast majority of geothermal plants use this technology.
The now-cooled water is returned underground after passing through a condenser, and injected back underground in order to continue the power cycle.
As the pressure lessens, a good portion of the water is converted into steam, which then powers a turbine and loses its heat Rather than having to go through a series of different actions, these plants utilize the steam which is released through vents directly in order to spin a turbine and power up a generator.įlash steam power plants use high-pressure water from underground, pumped upwards. There are three main types of geothermal energy plants currently in production, each of which has their own advantages and disadvantages.ĭry plants utilize steam from geothermal activity.
