What Liquid Is Used in Geothermal Systems

There are two commonly used types of fluids that can be circulated through the ground loop system. The Standard Geothermal uses a mix of water, antifreeze (Propylene Glycol), and refrigerant. While, the Waterless Geothermal System uses R-410A refrigerant.

What chemical is used in geothermal?

Stress corrosion cracking (SCC) is a type of failure promoted by a combination of the action of specific chemicals, such as chloride ion and tensile stress. The presence of oxygen and increased temperatures increases the severity of attack. This is the most dangerous form of corrosion in geothermal environments.

Is geothermal fluid toxic?

Air emissions Geothermal fluids contain dissolved gases which are released into the atmosphere. The main toxic gases are carbon dioxide (CO2) and hydrogen sulfide (H2S). Both are denser than air and can collect in pits, depressions or confined spaces.
