What technology is needed for geothermal energy?

There are three geothermal power plant technologies being used to convert hydrothermal fluids to electricity—dry steam, flash steam and binary cycle. The type of conversion used (selected in development) depends on the state of the fluid (steam or water) and its temperature.

Why geothermal energy is bad?

Geothermal plants can release small amounts of greenhouse gases such as hydrogen sulfide and carbon dioxide. Water that flows through underground reservoirs can pick up trace amounts of toxic elements such as arsenic, mercury, and selenium.

How deep should geothermal be?

Trenches are normally four to six feet deep and up to 400 feet long, depending on how many pipes are in a trench. One of the advantages of a horizontal loop system is being able to lay the trenches according to the shape of the land. As a rule of thumb, 500-600 feet of pipe is required per ton of system capacity.

What are the three requirements for geothermal energy?

A geothermal resource requires three things to generate electricity:

  • Fluid- sufficient fluid must exist in fractures and pore space within the rocks.
  • Heat- the rocks must be hot. …
  • Permeability- fluids must come into contact with the heated rock via fractures and pore spaces.
