<p>The water held underground in a geothermal system is under high temperature and pressure.

There are several different types of geothermal systems, dry steam, flash, binary, or even just geothermal heating. each varies in how they use pumps.

The water held underground in a geothermal system is under high temperature and pressure. Are pumps used to raise the very hot underground water to the surface or does the water rise under its own pressure? One source says that the water is pumped up[[1]](https://energy.gov/eere/geothermal/electricity-generation) while another says that it rises on its own[[2]](https://www.youtube.com/watch?v=kjpp2MQffnw). I am not sure if I just misunderstand the wording. Does anyone know which is correct?
