How geothermal power generation works

1
Hot fluid is pumped to the surface from reservoirs found miles below ground.2
The hot fluid passes through a heat exchanger and heats a secondary fluid (working fluid). The fluid is pumped back down to the reservoir through an injection well to be reheated, recharging the reservoir, and beginning the process over (primary cycle).3
The working fluid vaporizes and drives a turbine, which activates a generator and produces electrical power.4
The working fluid is cooled down in a dry cooling system to avoid losses through evaporation, before returning to the heat exchanger for heating (secondary cycle).5
The electric output of the generator is stepped up to a high voltage so power can be transmitted to the grid.6
The electrical power is transmitted via transmission lines.7
Power voltage is later stepped down (decreased) and electricity is delivered to end users through the final distribution system.
Why geothermal power
- The U.S. hosts vast amounts of untapped geothermal resources, supporting domestic energy independence.
- Geothermal power can create tens of thousands of jobs, with highly transferable skills from the oil and gas industry.
- Derived from natural processes, geothermal power is an on-demand, predictable energy source with zero fuel costs.
